Yup All correct, Great Job Kasi! Good job Ssanjinika! Now only waiting for number 5...

For number two...taken a step further is pair-a-dice (paradise)

Q1) What goes up a chimney down, but can't go down a chimney up? the answer is umbrella because it can go down a chimney (when closed) but can't go down a chimney (when it is opened up)

Q6) I walk, but have no legs. I sleep, but never dream. You can rock me in a cradle, but I am not a baby and I can go around the world faster than you can cross a room. What am I?

Yup the answer is yo-yo mentioned are all the tricks you can do with a yo-yo.

Suppose the light bulbs are sufficiently out of the rach of normal subway users. i.e. they cannot accidently come into contact with the bulbs, unless they are consciously attempting to reach it.

In such a case, one could think of pulling out a wire such the one who touches the base of the bulb receives an electric shock. Guess this should be effective and cheap, no pun intended.

In a small town there are four shoe shops of about the same size and each carries a similar line of shoes. Yet one shop loses three times as many shoes to theft as each of the other shops. Why and how did they fix the problem?

The shoe shops put single shoes as display items outside the shops. One shop put out left shoes, the other three shops put out right shoes. Thieves stole the display shoes but had to make pairs, so more shoes were taken from the one displaying left shoes. The manager changed the display to right shoes and thefts dropped significantly.

Subway problem, i dont think that is a proper solution.Normally what will be the mentality of a human being when unscrewing a thing ?Suppose he has to unscrew it anti-clock wise and if he tries and couldn succeed then obviously he will try clockwise also.This is the human nature.So it is not a proper solution i guess.

If getting a dead line means that the telephone number hasn't been assigned yet, they can purchase a new line with that number... This is easier, I guess...

sceptical if any telephone grid can handle 2 million calls at a time. even if 1% of target audience express interest that would amount to 20,000 calls. actually a blessing in disguise imho.

Three Gentlemen

There are three men standing in a row. All are wearing hats. The hats were chosen from a set of three black and two white hats. Nobody knows which color he himself is wearing. The third man knows the colors of first two men's hats and the second man knows the color of first man's hat.
The last man was asked whether he knew the color of his own hat. "No",he said.
The man in the middle was asked the same question and he too said,"No."
Now the first man was asked the same question and he said,"Yes,I know."
Did he really know? If yes, what was the color? and how did he arrive at the answer?

a question somewhat similar

There is a class of strength 60,every student in the class being very honest,very clever,very intellegent.The teacher comes in,and marks either blue or red color on the back of each student,students being unaware of the color behind them,and no one left uncolored and with at least one student being colored either red or blue.
After coloring each student ,the teacher leaves the class.
Now students can roam inside the class,notice the color behind any other student but cannot inform him about his color.
Now-
The teacher walks in every hour and asks "Those who are sure about blue color behind them may come out of class!"
p
So the question is --
How many students will come out at 1st hour

How many at 2nd hour?

ur answer is right but i dont think the reason is bcoz theives will have difficulty unscrewing the bulb. the bigger problem for them wud be to find the sockets where the bulb wud fit in. This solution was actually used in some public place (government funded obviously). such left-handed bulb sockets and screwbases are custom manufactured and DEFINITELY ARENT ECONOMICAL.

I interpret the bold statement as follows: "there is at least one red and one blue in the class".

If so, for a student to be sure that he has blue on his back, he musn't have seen blue on the back of any other student. Even if he sees one blue he will no longer be sure that his back is blue.

Except in the case where we have such a distribution the students cannot identify the colours on their backs.

Am I missing something ?

From: thamizhvaanan on Thu Apr 6 23:00:46 2006. [Full View]

I second ur idea prabhu but still that assumption is a lot optimistic and is highly improbable in case of random colouring.

and shakti, i am also not sure. but the solution definitely doesnt seem to be a time dependent one. i dunno why the questioner says how many in first hr , how many in 2nd hr so on.

rocketboy, my solution roughly follows ur thots. the students must strategize somehow. the question only says that they arent allowed to discuss their colors. so may be they are allowed to arrive at a strategy (further the question says that students are brilliant and even more bizarrely they are very honest, they must be a freaking odd bunch of students really).

in that case the simplest method wud be for each one to count the number of blue heads in the class. ppl who get odd answer form one group and ppl who get even answer form other group. ppl with similar colors will be grouped automatically (bcoz blue-headed fellows will count one less than actuall number of blue-heads, the exception being themselves naturally. so if there are odd no. of blue-heads all blue-heads will arrive at an even number while redheads get an odd answer.) so once they group themselves like this they get to know their headcolor by seeing others in the group.
in that case the entire gang gets out immedly. i am not sure why the questioner complicates this by asking a time-dependent answer.

if no strategy is allowed either, prabhu's answer cud be rite (with a lot of luck, obviously).
From: rocketboy on Thu Apr 6 23:33:32 2006. [Full View]

suppose they are not even allowed to discuss then consider this strategy.
all of them stand together and one by one they seperate from the group to join a line. A person always joins the line in a peculiar fashion.if the person who preceded him has a blue colour on his shirt then he goes and stands in front of that person .if not he stands behind him. so all those people having blue colour on their shirt will come to know their colour when they see someone stepping out to stand in front of them.
From: thamizhvaanan on Fri Apr 7 9:33:16 2006. [Full View]

rocket! u sent me a PM, i replied but no response from u??? anyway back to the problem

without arriving at a strategy how will they stand in a peculiar fashion. i mean, standing in a predetermined fashion is also a group strategy which ought to be discussed. when strategizing is allowed several variations are possible as u pointed out.

is there any method or group strategy such that everyone student will be able to arrive at it independently, using his intellect alone (i.e, that must be the best solution which everyone shud've guessed by their intelligence). in that case that wud be the answer. i am waiting for further ideas!!!
From: rocketboy on Fri Apr 7 10:54:56 2006. [Full View]

tamizh lets consider only three students.
let us call them a.b and c.

the teacher asks a " are you sure that the color on your back is blue ?"

a says yes when he sees that the other two students have red color on their back.(remember there should be one blue and one red atleast)

he says no when he sees one red and one blue.

now b's chance.

he notes down mentally a's answer. if a's anwser was yes then the colour on his back should be red.
if the answer was no he looks at c . he figures out that the colour on his back is blue if the colour on c's back is red and vice versa.

c use the same strategy.

this can be expanded upto 60 students.

and i did not get any reply. maybe some problem with my account. can you send it once again. thank you.

Good thinking rocket.
It seems u used the same strategy that was used for that hat puzzle.

From: Shakthiprabha on Sat Apr 8 5:42:35 2006. [Full View]

I dont understand one thing here.

The question says ATLEAST one blue or read.

Which means it can be ONE OR MORE of same colour.
(it can even be 59 red and JUST 1 blue)

When its 3 students probability theory is easier to conclude.

how can one conclude on his colour when there are 60 students?

What has it to do with 1st and 2nd hour?

(assuming 30 students find out in first hour,
the strength or no. of elements in the set is reduced their by making it easier )

Is there any answer for this?

Rocketboy,

I fail to understand HOW CAN 3 students strategy extend to 60 students

suppose 'a' assumes his colour is red (based on random 3 students where other 'b' and 'c' of the trio has blue) he goes around to another set.... to find 'red'
THAT DOES not mean he has blue OR does not assure him he has red either. IT CAN BE ANYTHING as in a class of 60 students ATLEAST ONE student has blue and ONE STUDENT has red. ............. (as I said before)

in that case the simplest method wud be for each one to count the number of blue heads in the class. ppl who get odd answer form one group and ppl who get even answer form other group. ppl with similar colors will be grouped automatically (bcoz blue-headed fellows will count one less than actuall number of blue-heads, the exception being themselves naturally. so if there are odd no. of blue-heads all blue-heads will arrive at an even number while redheads get an odd answer.) so once they group themselves like this they get to know their headcolor by seeing others in the group.
in that case the entire gang gets out immedly. i am not sure why the questioner complicates this by asking a time-dependent answer.

now, I think ur premise is convincing.

its easy to see how it can be extended to 60 students.

whatever be the number of students if the first student says yes then the rest of the students have to say no.

and next the time factor. the problem is time independent. i.e the teacher can come after every 1 hour or after every 2 hours. still it makes no difference.

but those people who were unable to answer in the very first round will be able to answer it in subsequent rounds if they think wisely.

i am not able to formulate this mathematically . but am sure this could be one of the ways to solve the problem.
From: thamizhvaanan on Sat Apr 8 10:48:27 2006. [Full View]

rocketboy, i think shakthi's doubt is credible. for example consider a slightly bigger example case of 5 students. suppose if one of them is bluehead, he sees red everywhere and hence comes out.

now wat if the teacher had painted two blueheads. none of the students will see everyone else's head being red ( i hope that is the condition based on which u answered). so no one will be sure. a blueheaded boy will see 1 blue out of 4, a redhead will see 2 out of 4 (all these assuming 2 ppl painted blue). infact i dont think ur solution will work if any more than 1 student are painted blue. even if one out of 60 students is painted red, he will know that he is red by seeing his mates, but he cant tell them. so rest of the class will not be sure. i hope u understand, if i am wrong somewhere pls tell

ok guyz enuf time spent on that stupid problem (everything that is beyond our contemplation is stupid ). lemme start with my 2nd puzzle. but this time i know the answer, so it shall not be a worthless exercise for u ppl

Five pirates have come across a treasure of 1000 coins. According to pirate rules the pirate of highest rank must make a suggestion on how to divide the money. If a majority agree to his suggestion then it is to be followed by all the pirates. However, if the suggestion does not get a majority approval then the suggesting pirate is thrown overboard (hmmm... democracy is functional atleast somewhere), after which time the remaining pirate of highest rank then makes a suggestion under the same rules. This process repeats, if necessary, until only the pirate of lowest rank is left, in which case he would get everything. Any pirate may suggest any distribution, rank does not guarantee getting more coins than anybody else. Assume that all pirates are infinitely greedy, infinitely logical, and infintely bloodthirsty, and that each pirate knows this to be true of every other pirate. The highest priority of each pirate is to get as much money for themselves as possible (they are pirates afterall ). The second highest priority is to throw overboard the other pirates (human nature ). A pirate will vote to throw another one over even if they have no monetary gain by doing so, and even if it would cost them their own life, but would not if throwing them over would cost even 1 coin (now this is insane) . How should the first pirate suggest dividing the money?

This was formerly introduced in supermarkets. this was done to prevent the employees from flicking rounded off amounts. everytime a transaction is made, a change has to be given to the consumer, for which an entry has to be made in the billing machine. rite?

The practice originated to ensure that the clerk had to open the till and give change for each transaction. This recorded the sale and prevented the clerk from pocketing the money. (From Sloane and MacHale, 1997.)

I do know that some companies ( DE SHAW )write sophisticated software for predicting share prices. also another way to do this is keep jotting down the share values over a period of time and do some simple regression analysis. I know these can't be answers to the puzzles.

A pirate will vote to throw another one over even if they have no monetary gain by doing so, and even if it would cost them their own life, but would not if throwing them over would cost even 1 coin (now this is insane) . How should the first pirate suggest dividing the money?

ok here is the solution with explanation for the above puzzle. a brilliant one indeed.

Call the pirate of highest rank pirate 1, the pirate of second highest rank pirate 2, and so on. Let (x,y,z,...) denote giving pirate 5 x coins, pirate 4 y coins, and so on.
If only pirate 5 were left he would get everything.

If only pirate 4 and 5 were left then pirate 4 has no hope, regardless of what he suggests pirate 5 will vote to throw him overboard, and overboard he will go. Thus it doesn't make any difference what pirate 4 suggests.

If only pirates 3,4, and 5 were left then pirate 3 has to come up with a scheme and he could count on pirate 4's support as long as pirate 4 got at least 1 coin. This is because if pirate 3 goes overboard pirate 4 knows he will get nothing. So pirate 3 would suggest (0,1,999) to which he and pirate 4 would vote 'yes.' Note that according to the problem pirate 4 would vote 'no' to (0,0,1000), even though a 'yes' vote would save his own life his pleasure of throwing pirate 3 over would be worth his own life.

If only pirates 2,3,4, and 5 were left then pirate 2 could count on pirate 3 voting 'no' unless pirate 3 got more than 999 coins, which would leave everybody else with 0, which obviously wouldn't pass. So pirate 2 should not count on pirate 3's support so he shouldn't waste any coins on him. If pirate 2 goes overboard he knows the money will be distributed (0,1,999). So if he offers 2 coins to pirate 4 and 1 coin to pirate 5 then he will get their support since they will come out better voting 'yes.' Thus pirate 2's suggestion would be (1,2,0,997) to which pirates 2, 4 and 5 would vote 'yes.'

Thus if all five pirates were left pirate 1 could count on pirate 2 voting 'no' since pirate 2 would get 997 if pirate 1 went overboard. So pirate 1 should not waste any coins on pirate 2 since he will vote 'no' anyway and concentrate on winning 2 votes from the other 3. If pirate 1 goes overboard the money will be distributed (1,2,0,997). So it would cost 2 coins to get pirate 5's support, 3 coins to get priate 4's support, and 1 coin to get pirate 3's support. Since he only needs to buy two votes the cheapest two are pirates 5 and 3. Thus pirate 1 would suggest (2,0,1,0,997) to which pirate 1, 3, and 5 would vote 'yes'.
hope it was clear enough!

NOV, wat you are saying is right. the rest of the coins placed will be even numbers but not exactly in the way u elucidated. They need not place the coins in ordered squares. the competitor is after all a devil. it will place the coins randomly. not in regular square plots.

the key here is to mimic the devils movement. if ur opponent starts the game, u can eliminate his chances of winning by repeating watever he is doing in the other half of the table. i.e place the coin in the symmetrically opposite position. by doin this we can ensure that we always place teh last coin. if the opponent can find a space to place a coin, so can we, at a symmetrically opposite position. but if the opponent starts the game by placing the coin at the centre (and if he knows the symmetry rule), we cant help it, coz there is no alternative. the best way to avoid this obvious defeat is to choose to play first and place teh coin in the centre

but unfortunately Devil, being a devil, doesnt know game theory and conceded to his request. Anyway wat rocketboy said was right. symmetry is the key.

Here is a good one. Came across this question in a puzzle contest in our college. Me and my friends cracked it and we thoroughly enjoyed doing tat.

An LCD (Liquid Crystal Display) can represent 0 to 9 digits. If you turn the LCD upside-down, some of the numbers still remain valid numbers for example 16 becomes 91. If you index all positive numbers (>0) that can produce valid numbers when you upside down the display (like 1st one is 1, 2nd one is 2, 3rd one 5... 7th one is 10), what is the 1190th number in this series?

5520.

I used brute force so I may have made a mistake. And I think there's a more elegant way to do it

From: thamizhvaanan on Mon Apr 17 12:55:30 2006. [Full View]

yes the answer is 5520, and there is some other elegant method. i will explain that later. Gud job

here is my logical explanation which i arrived at alone. it is loosely similar to the best method. later i was discussing this at class, one of my class mates came up with a beautiful mathematical analogy to explain my process better. i will post that later. for now the crude explanation

We can see that every 7th no. is a multiple of 10 and it proceeds with tens digit varying from 1,2,5,6,8,9. the required rank is divisible by 7 and hence it ends with 0. So let us forget the zero for the instance and come up with new ranking system, which is equal to the old rank divided by 7. Note that it gives numbers in mulitples of 10. so our new rank is 170. we divide it again by 7 hoping to get a number that ends with double zero. the quotient is 168 which implies that 168th number ends with double zero. follow similar procedure until u get to a rank with which u r comfortable (for which u know the value) and then work backwards.
From: Prabhu Ram on Tue Apr 18 3:33:32 2006. [Full View]

You call this crude This was itself was quite polished too.

I got to 1190 = (168X7) and (2X7)

Then 168 = 24 X 7
7th is 10
14th is 20
21st is 50
24th is 55
168th is 550
1156th is 5500 +14th is 20 so 5520

21 22 25 26 28 29 30

if we see this it resembles something familiar. yes it looks like numbers from decimal system, except that they wrap around every 7th number . that is, these sequence of numbers are analogous to a number system to the base 7.

so if we were to convert this "to-the-base 7" number to decimal system, we wud get the desired rank, becoz thats the system in which we count. but to convert it we need to map these numbers to the number system that we are familiar with. In a normal number system the numbers increment by 1 (like 1,2,3, etc.,) but here they go like 1,2,5,6, et., so let us map teh numbers

0 - 0
1 - 1
2 - 2
5 - 3
6 - 4
8 - 5
9 - 6

the required number would the the heptal equivalent of 1190. for that we need to convert 1190 to 7th base.

7 | 1 1 9 0
|------------
| 1 7 0 - 0
|------------
| 2 4 - 2
|------------
3 - 3

so the required heptal number is 3320, but we need to map this to the LCD number system. from the above table we find that the equivalent is

5520

Hope my explanations were clear . feel free to comment

brilliant answer tamizh. but calling the number system as base 7 is not appropriate. When you say some number is expressed in base 7 system then one expects to find numbers ranging from 0 to 6 alone .

nevertheless superb.

gud point rocketboy. yes you are right, u cant call it heptal system. i think i said, it is just analogous to that system and i made references to normal system also .

but later i did refer to it as "to the base 7". that was outta laziness

There is one more puzzle that deals with working with numbers of different base. This one is ultra-cool. Just think over it!!!

You have got 12 identical looking balls. one among them is different, in the sense, it is either heavier or lighter. You gotta pick the odd one out by using 3 weighings alone, using a simple physical balance. The balance is not graduated, so that u can only find the relative weight of the balls. How do u do that ?

Guess wat this puzzle has got to do with number systems There is one relatively simpler solution but we are techies. we will seek the complicated route instead

Let us denote the balls by B1, B2, ....... , B12 and
the pans (of physical balance) by P1 and P2.

Put B1, B2, B3 and B4 in P1 and B5, B6, B7 and B8 in the other.
We get the following cases.

Case-1: They balance each other.
Now we know that one of B9, B10, B11 and B12 is defective and balls B1 to B8 are non defective.
Remove all the balls.
Put B9 & B10 in P1 and B11 & B1 in P2.

We get following subcases.
Subcase-1: They balance each other.
Now we know that B12 is defective. Compare it with any other normal ball and find its defect (more weight or less weight).

Subcase-2: P1 goes down.
Now we know that either one of B9 and B10 is heavy or B11 is light. Compare B9 and B10 by putting them in P1 and P2. If P1 goes down then B9 is heavy. If P2 goes down then B10 is heavy. If they balance each other then B11 is light.

Subcase-3: P2 goes down.
Now we know that either one of B9 and B10 is light or B11 is heavy. Compare B9 and B10 by putting them in P1 and P2. If P1 goes up then B9 is light. If P2 goes up then B10 is light. If they balance each other then B11 is heavy.

Case-2: P1 goes down.
Now we know that one of B1, B2, B3 and B4 is heavy or one of B5, B6, B7 and B8 is light and balls B9 to B12 are normal. Let us denote balls B1 to B4 by H1 to H4 and balls B5 to B8 by L1 to L4.
Now put H1, H2, L1 and L2 in P1 and L3, B9, B10 and B11 in P2. Keep H3, H4 and L4 aside. Again we get following subcases.

Subcase-1: They balance each other.
Now we know that either one of H3 and H4 is heavy or L4 is light. Compare H3 and H4 by putting them in P1 and P2. If P1 goes down then H3 (B3) is heavy. If P2 goes down then H4 (B4) is heavy. If they balance each other then L4 (B8) is light.

Subcase-2: P1 goes down.
Now we know that either one of H1 and H2 is heavy or L3 is light. Compare H1 and H2 by putting them in P1 and P2. If P1 goes down then H1 (B1) is heavy. If P2 goes down then H2 (B2) is heavy. If they balance each other then L3 (B7) is light.

Subcase-3: P2 goes down.
Now we know that either L1 or L2 is light. Compare L1 and L2 by putting them in P1 and P2. If P1 goes up then L1 (B5) is light. If P2 goes up then L2 (B6) is light.

Case-3: P2 goes down.
Now we know that Either one of B1, B2, B3 and B4 is light or one of B5, B6, B7 and B8 is heavy. Now denote balls B1 to B4 by L1 to L4 and balls B5 to B8 by H1 to H4. Now follow the same procedure as in case-2.

Hope everyone can understand.

Try this one (very simple):

The defective machine
You are given 10 machines.
All the machines (except one) are identical and produce identical coins of 10 grams each. One machine is defective and it produces coins which are heavier or lighter than the other coins by 1 gram. You are given a balance on which the weight can be measured directly. You have to find the defective machine using the balance only once. You should also tell whether the defective coins are lighter or heavier.
From: Fire111999 on Wed Apr 19 2:50:08 2006. [Full View]

Defective machine:

Take 1 coin from 1st machine, 2 coins from 2nd machine, ... 10 coins from 10th machine. Weigh it. Since there are 55 coins, notice the difference between the scale reading and 550g.

So if it is x grams heavier, the faulty machine is machine x and the coins are heavier. If it is y grams lighter, the faulty maich is machine y and the coins are lighter.

OK here is the alternate solution for my puzzle (weighing of 12 balls).

The solution that was posted earlier was bang on target. This one is just to elucidate that an alternate method exists . The wonderful feature of this method is that what balls go on which pan does not depend on the outcome of any weighing; moreover, once the three weighings are completed, the counterfeit ball is immediately identified.

Let us take the left pan as our reference. The different states of pan are given by left pan down (D), left pan up (U) and both equal (E). Since three weighings are allowed the total number of possible outcomes is 3 ^ 3 = 27. If we dont exclude any of the balls in the weighings and ensure that same ball doesnt appear in the same side of pan more than two times, we will be eliminating outcomes DDD, UUU and EEE. So this leaves us with 3^3 - 3 = 24 sensible outcomes. Naturally we can use these 24 outcomes to uniquely represent 24 possibilites ( 12*2 (no. of balls * heavy or light)). So how do we do this? there is an elegant method of doing every bit of the answer using paperwork alone.

let us represent each of the balls by numbers 1 to 12. Initially let us assume that the odd ball is heavy. Now, one more rule. If left pan goes down (D), the outcome is taken as +1, for U it is -1 and for E it is 0.
D = 1
U = -1
E = 0

They key here is that, any number from 1 to 13 can be represented using a linear combination of 3^0 (1), 3^1 (3) and 3^2 (9). Like shown below:

1 = 1*1 + 0*3 + 0*9 = [1,0,0]
2 = -1*1 + 1*3 + 0*p = [-1,1,0]

The number sequence in square bracket can be called as a ternary system representaion of the decimal numbers. Such a representation for the rest of the numbers is shown below:
3 = [0,1,0]
4 = [1,1,0]
5 = [-1,-1,1]
6 = [0,-1,1]
7 = [1,-1,1]
8 = [-1,0,1]
9 = [0,0,1]
10 = [1,0,1]
11 = [-1,1,1]
12 = [0,1,1]

Note that number 13 can also be represented like this. These ternary numbers are the result of our weighings. For example, suppose if ball no. 6 is the odd ball, we have to place ball no. 6 such that the sequence of output results is [0,-1,1]. According to our convention, the first weighing shud be balanced which means, ball 6 is excluded. second one -1 which means left pan goes up. As with assumption, the odd ball being heavy should be placed in the right pan, to get such a result. Final one is +1 which means ball 6 is to be in the left pan.

Ok now is a loophole. So what if the odd ball is a light ball. Then our sequence gets upside down, and the effective decimal number that we get will be a negative number. So this solves the problem. If the odd ball is heavy, we get a +ve number, if it is light we get a -ve number.

For example, if the sequence of weighing results are like D, U, E, the corresponding ternary number is [1,-1,0]. The decimal equivalent is 1*1 - 1*3 +0*9 = -2. Which straightaway shows that, the oddball is ball no.2 and it is lighter (-ve)..

So following our plan, this is the weighing setup that we need to execute: (the platform doesnt support proper text formatting, all the additional blank spaces are getting truncated, so i use pipe symbol as a seperator. So please bear with me )

left pan |right pan
(1) first weighing 1,4,7,10 |2,5,8,11
(3) second weighing 2,3,4,11,12 |5,6,7
(9) third weighing 5,6,7,8,9,10,11,12

yes, this is outrageous, you cannot place unequal number of balls on each pan. Especially the last one, 8 balls in one pan and none in the other . There is a little intelligent workaround for this.

Ok i am feeling a bit tired. I will take a short break and continue this post immediately
From: thamizhvaanan on Wed Apr 19 12:48:58 2006. [Full View]

I am back!

As we developed final portions of our solution we ran into one problem, wherein there are unequal number of balls in the pans. The key here is to create an exception list. We select few balls and place them in the other pan, opposite to wat our initial plan demanded, so that the total number of balls in each of the pan in each of the weighing is 4.

OK, how is this going to affect our reading. Obviously, when the odd ball happens to be among the "exception" balls, our reading will be reversed,left pan will go up where it is supposed to go down and so on. So the readings are negative of actual reading. So wat does this mean ? when the outcome is +ve and the number happens to be one among these exceptions, it actually means the ball is lighter contrary to our initial design, bcoz it is an exception. Here is the final plan, with certain balls (7,9,11 and 12) having swapped their pans.

left pan | right pan
1,4,10,11 | 2,5,7,8
2,3,4,7 | 5,6,11,12
5,6,8,10 | 7,9,11,12

Hope teh explanation was clear enough.

yes fire it is a bit too complicated , but thats the way we work . ok we are not doing this extra bit of work without any advantages. In this method as i said earlier, none of the weighings outcomes affect any future weighings.
And this method would look a lot simpler if all the procedure is followed as a rule, rather than banging our head to try to understand the logic. All you gotta do is to label the balls and place them in the pans according to the scheme. Infact it wud be simpler than any of the methods discussed.
And more importantly this method can be extended to any number of balls, and we can determine teh minimum required weighings straitaway

ice cube problem:

stack one onto another with bottom one upright with water next one upside down empty, and alternate. therefore u have 4 full 3 empty. after some time, before the ice is fully formed, but outer layer of ice is formed, take 3 full ones and subs the 3 empty upside down trays with these trays. And place trays with water in the empty slots. so u have 4 half-formed trays and 3 trays with water. once the 4 trays are completely formed and the 3 trays are half-formed, remove the 4 trays, make the 3 trays take the upside down positions and put in 4 new trays with water. so once all the trays are done, u will have 10 trays of ice cubes, ie 120 ice cubes.

alternatively, is it ok to use some other board or sth to separate the trays, like to act as shelves?

they are clever indeed . Infact you are quite close to the answer which i got ( I think my answer takes a bit less time, pls correct me if I am wron). Only problem is I am not intelligent enough to make full sense of your explanation . Lost it somewhere midway.

Before I post my solution can u clarify ur explanation a bit more. Right from the place where u say "take 3 full plates" I thot 4 . Further i dont think u can play around with half-formed ice technically . Coz ice cubes dont form as surfaces. They more or less grow from a core (completely opposite to wat happens in a lake) and and due to buoyancy the core floats. But still your solution is ingenious. Just tell me how long will it take to mae 120 ice cubes, interms of time taken to make one full ice cube.

no, cos there are only 3 upside down positions. so one of the half-formed tray has to stay upright.

and i think ice cubes do form at the outside first. i remember shaking around half formed ice cubes and the water inside will move.

anyway, it takes 2 times as long as it takes to make one full ice cube.

now i understand your solution, quite ingenious and it takes teh same amt of time as my method. I think both are right. ok here is my answer:

In the first freeze attempt, stack 7 trays such that odd numbered trays are upright and the rest are inverted. Fill the uprite trays (supporting them on the inverted trays) with water to get 48 ice cubes in the beginning (4 upright trays). Remove all the icecubes. take 12 of them, place two ice cubes per tray (except the topmost) in the diagonally opposite corners. Now u shud be able to support the upper tray using these formed icecubes. Fill the rest of empty spaces with water. no. of new cubes formed are 84-12 = 72. So totally 48 + 72 = 120 cubes. And it does take the same time as fire's solution.

B is the shortest of all the 10 row-wise tall students. Let C be the student common to both the column of A and row of B. By definition B is taller than C and A is shorter than C. So definitely A is shorter than B.

Can u say some English words without any vowels (a,e,i,o,u) in it?

Recently,purchased a CD for my toddler son which has alphabets,vowels etc.This CD was made in the U.S. In it,they say that 'Y' is also a vowel.

I think here Y is also considered a vowel because one can easily form words like why,cry etc without using the other common vowels but will still have to use y.So because of this reason ,I think,Y is considered a vowel these days.

Y can be a vowel or consonant based on the context. for example in a word like "beyond" its usage is more or less like a consonant. whereas in words like sky, fly it is used as vowel. but basically y is considered as consonant so tha such puzzles can be asked

Plz tell how could this b possible?
2000+4000=0???

Once a mathematician borrowed Rs.4000/- from a rich man. After a few days, he borrowed Rs.2000/- from the same man.

Many days passed, the mathematician did not return the money to the rich man. The rich man went to the mathematician and asked to return the money.

But to his great surprise, the mathematician replied that there is no need to pay the debt.

"See here, friend" said the mathematician " the sum of 4000 and 2000 is equal to zero, so I do not have any balance to pay".

The rich man took the matter to the court. When the judge came to know this, he was astonished. He asked the mathematician to prove that sum of 4000 and 2000 is zero, and not 6000.

The Clever mathematician agreed. He said:

let a=4000, b=2000 and c=6000

So
a+b=c

Multiply both sides by (a+b), we get
(a+b)*(a+b)=c*(a+b)

Expanding we get,
a*a+ab+ba+b*b=ca+cb

Rearrange it as follows,
a*a+ab-ca=-ba-b*b+cb

a(a+b-c)=-b(a+b-c)

so a=-b

and so a+b=0

Hence 4000+2000=0 ???

How is this possible?
Please help the rich man to get his money from the clever mathematician as early as possible.

Now try this one. Actually even I dono the answer. I got this from my frnd.

An Intelligent Escape :

You have been convicted for some heinous crime. It is your destiny to spend the rest of your life in jail. However one day you find that things are not so murky.
The jailor is a good man and respects intelligence. He gives a chance to escape. But if one fails to escape, he meets his doom immediately!
Here is the situation. You are brought in a field. There are two doors. Only one will lead you to the outside world. There are two security guards, one at each door. You are allowed to ask one and only one question to only one of them. Wait, its not so easy. The critical thing is that one of them always speaks the truth and the other always lies. You don't know who is who.
After you ask the question, it will be answered and then you have to make a choice.
What question should you ask so that you get out of the jail?
From: Fire111999 on Sat Apr 22 4:13:17 2006. [Full View]

An Intelligent escape:

Question to ask: What answer would the other guard give if i ask him whether your door is the door to the outside?

i have highlighted the situation (right or wrong door) and the ans that the guard will give below.

if that is the right door and the guy is a liar, he will say that the other guard will say no cos the other guard will actually say yes.

if that is the right door and the guy is a harichandran (i.e. always tells the truth), he will say that the other guard will say no (cos the other guard is a liar)

same line of argument for if that is the wrong door, resulting in an ans of the other guard will say yes.

so, if the ans is the other guard will say no, that is the right door. if the ans is the other guard will say yes, that is that wrong door.

Whether a liar or true person, he shud b allowing the intelligent person to escape, as it is the order from his supreme and he can not violate his supreme's order.

no hulk, seeing puzzles as math equations is not a bad habit. infact for the given puzzle, we can formulate a math equation as,

3^n + 3^(n-1) + 3 ^(n-2) + ...... + 3 + 1 =>120

==> n = 4

Note that maximum no. of chocs available is 3^4 + 3^3 + 3^2 + 3^1 + 1 = 121. obviously the extra chocolate u can get by gving back the wrappers of the last 3 chocs that u got.

the problem with intuitive method is that u cannot work with big numbers using intuition alone.

yes you are right rocketboy. is it just a coincidence that everytime i ask a question u are the first one to answer it it would be better if u urself can give teh explanation.

Fire, the question means that there are particular numbers of cookies which you cannot form using any combination of cookie boxes. which is teh biggest of all such numbers? in other words, every integer above this number can be formed using a linear combination of 6,9,460.
for example, 461 is one such number which u cannot form using this number set. But 21 can be formed ( 2*6 + 9 ), and so can we form 459 (how?).

As rocketboy has said the solution, the answer is 923, which means u cannot form 923, but every single integer above 923, u can frame using 6,9,460. u guyz can still try to come up with an explanation for this

There are 4 possibilities

Head with the doubleheaded coin, other side head
Head with the doubleheaded coin, other side head
Head with the normal coin, other side tail
Tail with the normal coin, other side head

Nerd is right and I think his explanation is simple and convincing. Many ppl cant beleive it can be something other than 1/2. The puzzle is so much misleading.

I can give a mathematical interpretation also for this. This falls under the category of conditional probability.

Now let me introduce Bayes' theorem on conditional probability to explain why the answer is 2/3:

Let the events A1, ...,Ak for a partition of the space S such that Pr(Aj > 0 for j=1,...,k and let B be any event such that Pr(B) > 0. Then, for i=1,...,k,
Pr(Ai | B) = Pr(Ai) * Pr(B|Ai) / [ Σ (for j=1 to k) Pr(Aj)*Pr(B|Aj) ]

No it is not all that complicated. It means that Probability of A to occur given that B has already occured is unconditional Probability of A and B occuring together divided by unconditional probability of A occuring alone. ( The definition has been greatly simplified by the fact that B is a subset of A in this case)

i,e P(A | B) = P(A & B)/P(A),

In our problem, event A is getting a head, event B is choosing a double headed coin. event A&B is nothing but getting a head and the coin turning out to be a like-sided coin, which is basically probability of choosing like-sided coin.

P(A) = 3/4 ( 3 out of 4 sides are heads)
P(A & B) = 2/4

therefore P(A|B) = (2/4) / (3/4) = 2/3

Is that convincing ??

The first man (A) laughs seeing two red heads (B an C).
B laughs seeing C and A
A knows that B is laughing because he has seen at least one red head. He supposes that that red head is C (which he has himself seen).
C knows that A has seen at least one red head. He thinks/knows that it is B.
C also knows that B has seen at least one red head. He sees A's red head and thinks that is the head B is laughing at and laughs. Had A's head not been red C would have known that the red-head B is laughing at is his. So C would not have laughed.

So C's laughter tells A that his head is red.

OK time for a few "watch" problems

I just came across these questions, I myself have to work them out (I beleive I can ) and I know the answers for a couple of questions. Just dont get furious with me

1. Besides 12 o'clock, at what other times of day do the hands meet?
2. When are the hands pointing in opposite directions?
3. At what time of day does the line from 6 to 12 bisect the angle between the hands?
4. For a clock, it takes three seconds to strike three. How long will it take for the same clock to strike seven?
5. How many times a day, will the clock hands be @ right angles to each other?

good, can you express this in terms of an equation which gives all the times given the x value (hrs). I think that will throw more light on how u got the answer

From: sgokulprathap on Wed Apr 26 0:30:10 2006. [Full View]

We know the hour and minute hand meets each other 11 times in 12 hours.
So if it takes 12 hours for 11 times, it wil take 1hr 5.45 mins for 1 time.
After every 65.4545 mins the hour hand and minute hand wil b in same angle. i.e. We know @ 12, the angle between the hour and minute hand is 0. It wil again happen @ 1 hr 5.45 mins.
This logic applies for 1st, 2nd and 5th question.

For third question, if we find the minutes then the hour can be easily found. I've used some trial and error method for this one.

There are 12 possibilities as follows.
60/(1+(1/12))=55.38 mins.
55/(1+(1/12))=50.77 mins.
50/(1+(1/12))=46.15 mins.
45/(1+(1/12))=41.54 mins.
40/(1+(1/12))=36.92 mins.
35/(1+(1/12))=32.31 mins.
30/(1+(1/12))=27.69 mins.
25/(1+(1/12))=23.08 mins.
20/(1+(1/12))=18.46 mins.
15/(1+(1/12))=13.85 mins.
10/(1+(1/12))= 9.23 mins.
5/(1+(1/12))= 4.61 mins.

Anyway I got this just by trial & error. Someone may giv the solution more clearly. But I'm sure the answers r right.

right as usual pls explain the logic behind. It is the logic more than the answer that is beatiful
From: sgokulprathap on Thu Apr 27 7:18:54 2006. [Full View]

Bcoz if a number is to be divisible evenly by 225, it should b divisible by its prime factors.
Prime factor for 225 is 25 and 9.
IF a number is to b divisible by 25, it should end with 00 or 25 or 50 or 75. But since 0 and 1 are only required here, the result should definitely end with 00.

Also if the sum of digits is divisible by 9, the number wil b divisible by 9. Its simple maths. Since 1 and 0 only should b used, the answer drills down to
11111111100

These r the possibilities:
12 one steps
10 one steps and 1 two step
8 and 2
6 and 3
4 and 4
2 and 5
0 and 6.

So there r seven possiblities.
But anyway I'm not saying this as final answer. Bcoz he can use the same possibilty in different ways. So final answer wil b much more than this.

I'll solve this one tomorrow, if no one solve it till then.

First batsman takes a quick single.. fielder overthrows the ball and it hits the helmet of the wicket keeper which kept on the ground.. So 1+5 runs for the first barsman.

Then second batsman hit a SIX in the last ball..

I dont think so. Permutation is apt here.

Permutation definition:
If something can be chosen, or can happen, or be done, in m different ways, and, after that has happened, something else can be chosen in n different ways, then the number of ways of choosing both of them is mXn.

On the other hand in combination,
combinations of abcd taken 2 at a time is
ab, ac, ad, bc, bd, cd. Note in permutation ab is different from ba. But it's not so in combination. i.e. the order of occurence is not considered in combination, which is wat more important here.

So I think the answer is:
13P0+11P1+9P2+7P3+5P4+6P2+7P0=445.

From: rocketboy on Sat Apr 29 8:37:54 2006. [Full View]

gokul sir, now we are in a deadlock . since tamizh and myself independently arrived at the answer it makes me believe that 233 is indeed the right answer and also combination appears to be a better method to wield. But I am not sure. I would really like someone with good mathematical skills to step in and resolve the issue for us.

From: thamizhvaanan on Sat Apr 29 13:21:29 2006. [Full View]

I guess this problem is very misleading in this regard. take a board having 7 slots for marbles. in how many ways can u place two marbles in those 7 slots?

I hope u wud agree that it is 7C2. Exact same situation happens where u have 7 moves in total to make, and two of those moves happens to be a single step, rest being double steps. so our aim is to place these single steps in 7 moves available, which i beleive is analogous to placing the marbles.

Further, we dont differentiate between a double step that happens in the first move from the same that happens in the last move. For e.g, if we name the Double steps as D1,D2 and so on, we are not concerned abt the order in which they are placed (D1,D3,D2 is same as D3,D1,D2) but rather the position of these moves is important to us, bcoz that defines the number of unique ways. I hope this interpretation of combination conforms to ur explanation which says,

Quote:

ab, ac, ad, bc, bd, cd. Note in permutation ab is different from ba. But it's not so in combination. i.e. the order of occurence is not considered in combination, which is wat more important here.

Look at this possibility.
Batsman A, hits the ball and sets off for three runs, due to over throw the ball reaches the boundary, but he was one short during his 1st or 2nd run and hence given 6 runs instead of 7 runs. So he reaches 100.
Batsman B hits a six of the last ball. He also completes 100 and his team also wins.

Ok. Chinna vayasila kelvipatta puzzle.

There are 3 ponds near a tree. The ponds are so special, such that whatever u put into the pond, it wil get doubled.
Now the puzzle is to make equal number of flowers in all 3 ponds.
Conditions:
1) U hav to pluck the flowers from the tree only once.
2) Once pluck the flowers from tree, u hav to put all the flowers in 1st pond. Now pick some flowers from 1st pond and put all of them in 2nd pond. And finally choose some flowers from 2nd pond and put them in 3rd pond.

So the questions are:
1) Minimum how many flowers u should pluck from the tree (ofcourse, not zero)?
2) How many flowers wil there b in each pond?

Now the puzzle is to make equal number of flowers in all 3 ponds.
Conditions:
1) U hav to pluck the flowers from the tree only once.
2) Once pluck the flowers from tree, u hav to put all the flowers in 1st pond. Now pick some flowers from 1st pond and put all of them in 2nd pond. And finally choose some flowers from 2nd pond and put them in 3rd pond.

So the questions are:
1) Minimum how many flowers u should pluck from the tree (ofcourse, not zero)?
2) How many flowers wil there b in each pond?

Is it 1). 7 flowers and 2). 8 flowers

Yes it is 7 and 8.

From: thamizhvaanan on Tue May 2 4:47:30 2006. [Full View]

yea, even i've heard this puzzle during childhood. that time i took the answer for granted and was amazed at that time.

this time out of utter joblessness i put it in mathematical form

let x be the no. of flowers plucked, y be the no. that is taken out of the pond to be put in the 2nd lake. then the no. of flowers left in lake 1 is (2x - y). the same no. of flower must be ther in 3rd lake too. which means the no. of flowers taken out of 2nd lake is half of (2x-y) and so the no. of flowers left in lake 2 is (2y-.5(2x-y)).

equating the no. of flowers in lake 1&2 we get 7y=6x. the smallest positive integer solution are x = 7 and y = 6 and hence our answer.

ufff!!! so much sweat for one simple question!! as i said, i am utterly jobless

agreed. here is one readymade puzzle

An army surgeon needs to operate on 3 different soldiers who got hit during reconnaissance. The problem is that the supply truck hasn't restocked the field hospital and surgical gloves are just about gone.

She cannot come in contact with the blood of any soldier, and there is to be no blood contact between soldiers.

How can the surgeon operate on three different people when she has only 2 pairs of gloves.

If so, then this is the possibility:

Let the Gloves b A & B.

For third person, the surgeon has to put both Gloves, with the outer Glove's changing innerside and outerside.

no, the inside portion will still be contact only with the outside portion of inner glove. i.e, two of the stained sides will be in contact with each other while one among the clean sides will be in contact with surgeons hand, other side goes into the person who is going to die in the surgery

No Hulk. I think u r confused with surgery with third person.

Consider this case for third person.
Nurse first wears Glove A, which wil hav blood on outerside.
Now she take Glove B. Turn its innerside out.
So Glove B wil now hav blood on innerside and not on outerside.
Now the nurse wil wear Glove B over Glove A.
Note now nurse is not in contact with blood as she is having contact with innerside of Glove A. Now she can operate safely for third person. Third person wil not get touch with other's blood, since Glove B's outerside does not hav blood now.

Am I still confusing?

From: Hulkster on Wed May 3 1:25:14 2006. [Full View]

Gokul sir maybe we shall think like this...the 75 steps could be actually

The escalator is moving know, when they come down.

From: Hulkster on Wed May 3 1:37:49 2006. [Full View]

If b moves faster than A....it could possibly mean he is also moving faster than the escalator...that means even before the escalator can bring him down...he is moving a big chunk of the length of the escalator which is why 75 steps..while A is just relatively moving the speed of the escalator so thats why 50 steps for him.

How?
From: thamizhvaanan on Wed May 3 1:41:26 2006. [Full View]

let B move at 3 steps per second, so A moves at 1 step per second.

Let us assume that the escalator comes down at n steps per second. so by the time B has come down 75 steps, escalator wud have moved 75/3 * n = 25*n steps.

so the net no. of steps traversed is 75 + 25n

similarly by the time A has moved 50 steps, the escalator would have travelled 50*n steps. the net no. of steps travelled is 50 + 50*n

equating both we get, n=1 and thereby total no. of steps = 100

does that vibe well with the question ?

75/3 is 25 steps

if the escalator is moving at a normal speed...it means it is moving twice as fast as a stationary escalator(stationary does not move) which means 2/4 of the whole escalator length.

As for B he is moving three times as faster than a moving escalator speed which means 3/4 of the whole escalator length.

We know any number to the power of zero is one.
i.e. a^0=1.
Can anyone prove it?
From: rocketboy on Tue May 9 1:43:49 2006. [Full View]

I don't know if this is the right method to prove it.

a ^ x * a ^ y = a ^ (x+y)

if x is zero then the result is a ^ y.

a ^ x * a ^ y = a ^ y ( when x is zero )

which means a ^ x =1 ( when x is zero )

which means a ^ 0 =1.
From: sgokulprathap on Tue May 9 1:48:04 2006. [Full View]

U r right rocket.

I'll put it this way.

a ^ 0 can b written as a ^ (n-n)
i.e.
a ^ 0 = a ^ (n-n) = a ^ n * a ^ (-n) = a ^ n * 1/(a^n)=1.
From: rocketboy on Tue May 9 1:56:08 2006. [Full View]

tamizh raed it carefully .i have given the reason why a ^x * a ^ y =a ^ y when
x=o in the previous line

by laws of exponents a ^ x +a ^ y =a ^ (x+y)
now substitue x =0 .

then a ^ 0 * a ^ y = a ^ (0+y) = a ^ y.

an irrational number is one which has got endless number of deciamal numbers in it, as well as cant be expressed as a ratio, like pi or e . The golden ratio phi is said to be the most irrational number.

May b this one makes sense:
This is based on the assertion that every number is uniquely representable as a product of primes.
let (p/q) = sqrt(2) for some integers p and q.
Then p^2 = 2q^2.
Factor both p and q into a product of primes.
p^2 is factored into a product of the very same primes as p each taken twice. Therefore, p^2 has an even number of prime factors. So does q^2. Therefore, 2q2 has an odd number of prime factors. Contradiction.
So sqrt(2) has to b irrational.

I think this serves the purpose. But lemme think whether there's any better possible proof.

A high school has a strange principal. On the first day, he has his students perform an odd opening day ceremony:

There are one thousand lockers and one thousand students in the school. The principal asks the first student to go to every locker and open it. Then he has the second student go to every second locker and close it. The third goes to every third locker and, if it is closed, he opens it, and if it is open, he closes it. The fourth student does this to every fourth locker, and so on. After the process is completed with the thousandth student, how many lockers (and which lockers) are open?

Much simpler puzzle:

Two trains travel toward each other on the same track, beginning 100 miles apart. One train travels at 40 miles per hour; the other travels at 60 miles an hour. A bird starts flight at the same location as the faster train, flying at a speed of 90 miles per hour. When it reaches the slower train, it turns around, flying the other direction at the same speed. When it reaches the faster train again, it turns around -- and so on. When the trains collide, how far will the bird have flown?
From: thamizhvaanan on Tue May 9 5:25:48 2006. [Full View]

The state of a locker (open or closed) depends upon its position number. If the position number is a prime number it will be closed bcoz, a prime number has only two factors. The same holds true for all numbers that have even number of factors.

My initial brute force analysis tells me that all square numbers have odd no. of factors. I havent yet checked it out with a proper mathematical treatment. On a similar note, I am not sure if there are numbers outside square numbers that have odd numbers of factors.

Assuming that the bird spends zero time in changing direction, and moves at constant velocity without any acceleration or deceleration, its distance covered is equal to time taken for collision times velocity. Time taken for collision is 1 hr, so the distance travelled by the bird is 90 miles.

Two mathematicians, Albert and Isaac, chat. Isaac says he has three children who all have the same birthday (but who weren't necessarily born in the same year). Albert asks their ages. Isaac replies, "The product of the ages of my children is 72." Albert points out that this is not enough information to determine their ages. Isaac responds with another clue -- he tells Albert the sum of the ages of his children. But Albert again points out that there is not enough information. Finally Isaac says, "My youngest child is named Galileo." At last, Albert correctly determines the ages of Isaac's children. What are the ages?

The possible sets of ages are
2,2,18
2,3,12
2,4,9
2,6,6
3,4,6
3,3,8

Out of these all the sums are unique except 2,6,6 and 3,3,8.
If the set of ages were 3,3,8 then Isaac cannot say youngest son.. as the youngest are twins..

Hence the ages of Isaacs children are: 2,6,6

Toy Store:
A toy store ordered 7 small bags and 18 large bags of identical marbles. When the marbles arrived, it was discovered that the bags had broken during shipping, and all 233 of the marbles were rolling around loose in the box. How was the store's manager able to determine how many marbles were supposed to go in each of the small bags and how many were supposed to go in each of the large bags?

Nine minute egg:
You're a cook in a restaurant in a quaint country where clocks are outlawed. You have a four minute hourglass, a seven minute hourglass, and a pot of boiling water. A regular customer orders a nine-minute egg, and you know this person to be extremely picky and will not like it if you overcook or undercook the egg, even by a few seconds. How will you do it?

For the first question...the answer would be 5 and 11.

How he would derive is this.

anything multiplied with 18 will be a even number

so the multiples of 7 in this case have to be all odd and the sum of this two bags of marbles has to be 233.

7x + 18y = 233 where x is odd.

The highest possible multiple of 18 is 198 as it should not exceed the total.

insert this into the equation and we get 7x + 18(12) = 233. where 12 * 18 = 198.

7x = 35
x = 5.
From: Hulkster on Wed May 10 0:25:09 2006. [Full View]

For the second question...i do not know if this is right but here is a try.

I suggest he runs the seven minute hourglass and waits for it to allow all the sand to seep through before immediately switching to the four minute hourglass...once half of the sand has seeped through for the four minute hour glass, stop boiling the egg.

No Hulk, It's difficult to b accurate in finding wen a glass is half-filled. Remember accuracy is more important here. But its much simpler. Think out of box.

The cook starts the 7 min hrgls and 4 min hrgls at the same time. 4 min hrgls is run repeatedly. When the 7 min hrgls is run fully he starts boiling the egg. when the 2nd cycle of 4 min hrgls is over it is 1 min i.e (4*2)-7. Then he runs the 4 min hrgls 2 more times for the balance 8 mins.

Ur answer seems OK. But it actually takes 17 minutes to prepare a nine minute egg. There's a better method to make nine minute egg in nine minutes. But ur logic is right. Try to come up with the better solution.

1. Flip both
2. When the 4 minute HG runs out, flip it again - total 4 mins
3. When the 7 minute runs out flip it again - total 7 mins
4. When the 4 minute HG runs out again, flip the 7 min glass - total 8 mins (7 min glass would have run only for a minute now)
5. When the 7 minute now runs out, its 9 minutes!!

Chess Challenge:

A person who is not a professional chess player (he knows to play, but not as gud as grandmasters. Let us call him as Gokul), was travelling in a plane with chess masters Gary Kasparov and Vishwanathan Anand. Gokul challenges Kasparov and Anand that he'll play against both of them simultaneously and prove his talent. Kasparov and Anand agreed.

Match started. As both Kasparov and Anand r genius in chess, they left the option of picking white / black piece to Gokul.

Winner from each game wil get 2 points. If a match is drawn, both players wil get 1 point each.

So accepting the fact that Gokul is not a genius like Anand or Kasparov, wat's the minimum point that Gokul is assured of the two games? Remember both matches start @ same time.

Two half-full barrels are dumped into one of the empty barrel to make it full.
Two more half-full barrels are dumped into another one of the empty one.
This results in nine full barrels,
three half-filled barrels,
nine empty barrels.

Each son then gets three full barrels, one half-full barrel, and three empty barrels.

127 is right, but tell the logic which is more interesting than the answer.

Both of the finalists have to play 7 matches in total, the last one being final. It means that there are 7 levels in the tournament. If we work backward from finals, one final match, then two semi-finals, four quarter finals and so on.

so the total no. of matches is 1 + 2 + 4 + 8 + 16 + 32 + 64 = 127.

The thumb rule is that, summation 2^i (from i=1 to i=n-1) = 2^n - 1.

Thamizh logically u r right. But there's much easier practical solution for this. That's y I askd this one. Otherwise I know it can b solved using ur equations.

Ok. Lemme tell the solution for Tennis Tournament in simpler way by not using any EQUATIONS.

Except the champion everyone would have lost a match. And since losers r eliminated after each match no one wud hav lost more than one match.

Hence if u just count number of losers, then thats the answer. Here since 128 players r playing, there wil b 127 losers (Champion wud hav won all the matches). So 127 is the answer.

Crossing the Bridge:

Mr. Slow, Mr. Medium, Mr. Fast, and Mr. Speed must cross a rickety rope bridge. The bridge can carry at most two people at a time. Furthermore, it's dark, and there is only one flashlight; any single person or pair of people crossing the bridge must have the flashlight with them. (The bridge is too wide for the flashlight to be thrown; it must be carried across.)

Each man walks at a different speed. A pair travelling together must walk at the rate of the slower man. Mr. Slow can cross the bridge in at most 10 minutes; Mr. Medium can cross in 5 minutes; Mr. Fast can cross in 2 minutes; Mr. Speed can cross in 1 minute.

Measuring 45 minutes:

You have two slow-burning fuses, each of which will burn up in exactly one hour. They are not necessarily of the same length and width as each other, nor even necessarily of uniform width, so you can't measure a half hour by noting when one fuse is half burned. Using these two fuses, how can you measure 45 minutes?

Measuring 45 minutes:

You have two slow-burning fuses, each of which will burn up in exactly one hour. They are not necessarily of the same length and width as each other, nor even necessarily of uniform width, so you can't measure a half hour by noting when one fuse is half burned. Using these two fuses, how can you measure 45 minutes?

well, this must be it..

ANSWER:

since a fuse takes 1 hour to burn, lighting it on both the sides will make it burn twice as fast, so, take both the fuses light the first one on both the sides and the second one on only one side at the same time. By the time the first fuse burns out completely we know that half an hour has elapsed, so, the second fuse has half hour left to burn out completely. At this moment light the second fuse from the unburnt side this will burn it in 2wice as fast as the original time (30 min.), this means it will burn out in 15 min. 30 + 15 = 45!

gokul, is my logic correct?

Crossing the Bridge:

Mr. Slow, Mr. Medium, Mr. Fast, and Mr. Speed must cross a rickety rope bridge. The bridge can carry at most two people at a time. Furthermore, it's dark, and there is only one flashlight; any single person or pair of people crossing the bridge must have the flashlight with them. (The bridge is too wide for the flashlight to be thrown; it must be carried across.)

Each man walks at a different speed. A pair travelling together must walk at the rate of the slower man. Mr. Slow can cross the bridge in at most 10 minutes; Mr. Medium can cross in 5 minutes; Mr. Fast can cross in 2 minutes; Mr. Speed can cross in 1 minute. Suggest a way to the four men to cross the bridge in lesser time?

ANSWER

1. Mr. Fast and Mr. Speed cross first now that takes two minutes.
2. Mr. Fast returns with the flashlight now that takes two minutes.
3. Mr. Slow and Mr. Medium cross now that takes taking ten minutes.
4. Mr. Speed returns with the flashlight now that takes one minute.
5. Mr. Fast and Mr. Speed cross againnow that takes two minutes.

2+2+10+1+2=17 mins . now this one took some time to solve. good question.

Except the champion everyone would have lost a match. And since losers r eliminated after each match no one wud hav lost more than one match.

Hence if u just count number of losers, then thats the answer. Here since 128 players r playing, there wil b 127 losers (Champion wud hav won all the matches). So 127 is the answer.

I didn't look into their analysis much. I'll look after for puzzles there. If I can get answers, I'll check whether my answer is right or wrong. If I cant find answer I'll just skip it. Probably I may hav to look for their analysis later. Dont hav patience and time now.

Its very simple TV.

//In each of these puzzles, you are given a number that you must construct out of several other numbers. You do this by taking the numbers and performing addition, subtraction, multiplication, and/or division operations on them. Each number must be used in the calculations exactly once, and only these four operations listed may be used. You may parenthesize your expression however you wish. For example, 5 may be obtained from 1, 2, and 3, with the expression (3 + 2) � 1.
Multiple solutions are possible for many of these puzzles.//

Death In The Desert

A dead body is found in the middle of the desert. It was of a man who was wearing a backpack. His ribs were crushed. The post mortem shows that he died suddenly, 1 month ago. Yet no one has crossed the desert for past 3 months. How did he die ?

Death In The Car

A man and a his wife were going in their car at high speed down a country road. Suddenly the car swerved off the road and hit a tree. The man was not seriously injured and looking around, he saw a distant light from a house quite far off from the road. So he decided he would go there and ask for help from the people living in the house.

Making sure that his wife was still alive, he took out the keys from the car, rolled all the windows up, and locked all the doors. Then he went on to the distant house, but found that there was a lock on the door and no one lived there at present. The light he had seen was a window reflection of the moon overhead. Dispirited but determined to help his wife, he returned to the car.

To his utter shock he found that his wife was dead, and that there was someone in the car he had never seen before.

No physical damage was done to the car, and it was still locked.

Now what was the cause of the woman's death

Where did the stranger in the car beside her come from

Ten people land on a deserted island. There they find lots of coconuts and a monkey. During their first day they gather coconuts and put them all in a community pile. After working all day they decide to sleep and divide them into ten equal piles the next morning.

That night one castaway wakes up hungry and decides to take his share early. After dividing up the coconuts he finds he is one coconut short of ten equal piles. He also notices the monkey holding one more coconut. So he tries to take the monkey's coconut to have a total evenly divisible by 10. However when he tries to take it the monkey conks him on the head with it and kills him.

Later another castaway wakes up hungry and decides to take his share early. On the way to the coconuts he finds the body of the first castaway, which pleases him because he will now be entitled to 1/9 of the total pile. After dividing them up into nine piles he is again one coconut short and tries to take the monkey's coconut. Again, the monkey conks the man on the head and kills him.

One by one each of the remaining castaways goes through the same process, until the 10th person to wake up gets the entire pile for himself. What is the smallest number of possible coconuts in the pile, not counting the monkeys?

This is a lateral puzzle

Assume there are approximately 5,000,000,000 (5 billion) people on Earth. What would you estimate to be the result, if you multiply together the number of fingers on every person's left-hands? (For the purposes of this exercise, thumbs count as fingers, for five fingers per hand.) If you cannot estimate the number then try to gues how long the number would be.

Answer: 2519

Solution:
From the 1st man, it is known that the total must be one less than a number divisible by 10.
From the second man, it is known that that total must be one less than a number divisible by 9.

After considering all 10 people the final number must be one less than a number divisible by every number from 1 to 10. Certainly 10!=3628800 works but there is smaller solutions. The smallest answer is LCM(1,2,3,4,5,6,7,8,9,10)-1 = 7*2*2*2*3*3*5-1 = 2519.

Shud v assume all people on earth hav left hand. If not, then the answer shud b zero. Bcoz in normal case atleast one people in the earth wud b there without left hand. So zero multiplied by zero is zero only.

So the answer is ZERO.

Lets name the three men as A, B and C.
And let the truth teller will be referred to as T, the liar as L, and the random answerer as R. Now one must actually know the truth in order to tell it or to lie about it. So, we need to ask a question to A that he cannot possible know the answer to, ie: �will B and C both answer my question truthfully?� the only person who can give an answer is R. Neither T nor L know the truth, thus they cannot answer the question, either yes or know.

So, if A is R, then you will get a yes or no. Now you just need to determine if B is T or L. This can be done with a simple question such as �Are you a male?�.

If A is T or L, they will be unable to answer, now you need to determine if A is T or L. Do this the same way as above. If A is T, simply ask them is B is the one who always lies. If A is L, ask them if B always tells the truth, if they answer yes, then B is R, if they answer no, then B is T.

Ramky, u r rite.

But lemme tell u how I worked it out. Let the 3 men be A, B and C.

There r totally 6 possibilities:

I-Truthteller-Liar-Random Man
II-Truthteller-Random Man-Liar
III-Liar-Truthteller-Random Man
IV-Liar-Random Man-Truthteller
V-Random Man-Truthteller-Liar
VI-Random Man-Liar-Truthteller

Follow these steps to determine which possibility listed above is correct:
1.Ask A, "Is B more likely to tell the truth than C?"
>If yes, go to step 2.
>If no, go to step 5.

2.Ask C, "Are you the random man?"
>If yes, go to step 3.
>If no, go to step 4.

3.Ask C, "Is A the truthteller?"
>If yes, then scenario V is the case.
>If no, then scenario II is the case.
4.Ask C, "Is A the liar?"
>If yes, then scenario IV is the case.
>If no, then scenario VI is the case.

5.Ask B, "Are you the random man?"
>If yes, go to step 6.
>If no, go to step 7.

6.Ask B, "Is A the truthteller?"
>If yes, then scenario VI is the case.
>If no, then scenario I is the case.

7.Ask B, "Is A the liar?"
>If yes, then scenario III is the case.
>If no, then scenario V is the case.

By following the steps above, you will only ever ask three questions in all, and the answers will determine the identities of the three men.

What is unusual in these paragraphs?

1) How quickly can you find out what is so unusual about this paragraph? It looks so ordinary that you would think that nothing is wrong with it at all, and, in fact, nothing is. But it is unusual. Why? If you look at it, study it and think about it, you may find out, but I am not going to assist you in any way. You must do it without coaching. No doubt, if you work at it for long, it will dawn on you. Who knows? Go to work and try your skill. Par is about half an hour. So jump to it and try your skill at figuring it out.
Good luck --do not blow your cool.

Nerd, rocketboy's answer is correct. The kattai is at the center of a circle with radius 25 ft. The horse is standing at the circumference, and the hay is at 180 degrees from the horse.
But my answer is also right. The puzzle has not mentioned any kattai. So the rope may be tied to the horse but it is loose. So the horse can go anywhere and pachak, pachak.

One was fastening the rope . Even before he could complete ,the other guy, who was attached to the other end of the rope , makes a jump. Both fall of the bridge . They hit the rocks in the shallow river and die.

In another scenario one person is an onlooker who stands below the bridge. Again the rope gives way and the second person lands on the onlooker. Given the height of the bridge falling on another person does not cushion the fall. I've read somewhere that beyond a certain height jumping into a pool of water has the same effect as landing on soft earth.

Rajinder Singh was going by flight from Calcutta to Darjeeling.
He was thinking fondly of Parminder Kaur whom he had married
just last fortnight, and was looking outside the Airbus A310 window,
thinking how fortunate he was that she had concented to marry him,
inspite of another wealthy suitor also proposing to her.

While musing how lucky he was that the official tour came
after his honeymoon, he happned to see an unexpected bird.
Within a few minutes he was dead.
How did he die ?

Clues :
1. He did not commit suicide.
2. He was not suffering from Heart attack or any such disease
which could have killed him.
3. He was not poisoned by consuming the food given by the airhostess.

This is easy. Birds are always a safety hazard to flights. If a bird collides with a plane or a jet during take off or touch down( only at that time aircrafts flyu at low altitudes) then it cab be fatal. what happens is usually the bird gets sucked into the engne resulting in an engine failure. In 1995 a Dassault Falcon 20 crashed at Paris airport after getting hit by a bird.

Very good sanjinika!
Only one pick is needed. You will pick nut-nut-bolt, or bolt-bolt-nut. From this you can find the box that has only the nuts, or only the bolts. And look at the label. If the label is right, then you know that the remaining 2 boxes are labeled wrong, so interchange the labels for those boxes. If the first box is labeled wrong then interchange the labels between the first box, and the box that has the label that belongs to the first box!

The label will be WRONG always.. Anyways u ve given the answer!

to TSO
to SS

Let me explain in my words:

#1) Pick from the box labelled mixed
#2) If you get a nut, then re-label the nut-box to bolt
#3) re-label the bolt-box to mixed, mixed box to nut

#2) If you get a bolt, then re-label the bolt-box to nut
#3) re-label the nut-box to mixed, mixed box to bolt

#2) You wont get a mixed thing here, coz the box is labelled mixed, incorrectly

Hope it makes sense

nerd,
If the labels are interchanged there will only be 2 boxes that will be labeled wrong, and one box will always be right.
I call picking one from each box as one pick, and not 3 picks If my first pick is nut-nut-bolt, I know that the bolt came from the bolt box. If my first pick is bolt-bolt-nut, I know that the nut came from the nut box.

You are saying that every box is labeled wrongly. In that case, one has to check only the 'mixed' box. But if the labels are simply interchanged between the boxes then my answer is right. But for both only one pick is needed.

David was exploring the remote parts of the Sahara desert. As he was told that no one had been to that particular district for the past 3 months, he was curious about the place. But while wandering near some rocky area, he came upon a dead body. It was of a man who was wearing a special outful. His bones were sticking out of the sides - so severe were the injuries which lead to the man's death. David arranged to take the body to a hospital and got them to do the post mortem. The post mortem showed that he died suddenly, about one month ago.

Slapped for eve teasing

In one particular city of North India, eve teasing in some colonies was becoming unbearable to the college going girls. The local police woke up to this fact and after an anti eve teasing drive, arrested 10 boys from one area. In addition to the severe fine and prison sentence, the Assistant Commissioner of that locality included another punitive action against the eve teasers - he asked the affected girls to slap the errant boys right there in the police station. Now, if a boy and a quarter get a slap and a quarter from a girl and a quarter, how many slaps would 10 boys get at the same rate from a girl?

A column of soldiers one mile long is marching forward at a constant rate. The soldier at the front of the column has to deliver a message to the soldier at the rear. He breaks rank and begins marching toward the rear at a constant rate while the column continues forward. The soldier reaches the rear, delivers the message and immediately turns to march forward at a constant rate. When he reaches the front of the column and drops back in rank, the column has moved one mile. Question- How far did the soldier delivering the message march?

Take 1000 pounds directly to city B, consuming 200.08 pounds on the way, leaving 599.84 pounds and take back 200.08 pounds to eat on the way back.
Take the last 1000 pounds directly to city B, consuming 200.08 pounds on the way, and depositing an additional 799.92 pounds of grain, for a total deposit of 1399.77 pounds.

If v assume the column took n hours to move 1 mile, the problem here is to find out how much distance the front line soldier moved in that n hours. Its seems I may hav to refresh some of my elementary maths formulas.

The camel eats only when it carries the grain, and not when it returns from B to A without carrying anything.
Carry 1000 pounds each time to 500 miles from city A. In 10 trips, there will be 5000 pounds of grain at 500 miles from City A (5000 pounds eaten by the camel). Now in 5 trips you can take 2500 pounds to City B (2500 eaten by the camel). You can deliver 2500 pounds to City B.

From: kannannn on Wed Jun 21 7:38:49 2006. [Full View]

gokul prathap, the solution becomes much simpler using relative speeds and relative distances

marching rate of column = m1
marching rate of soldier = m2
distance where the first soldier meets the second soldier = d from the starting point
time taken to meet the last soldier = t
time taken to join the ranks after delivering message = t1
the relative speed of the soldier before delivering message = m2+m1.
relative distance covered before delivering message = 1 mile
relative speed of the soldier after delivering message = m2-m1
relative distance covered after delivering message = 1 mile
thus, t = 1/(m1+m2), d = m2/(m1+m2)
or (m1/m2) = (1-d)/d -----------(a)

t1 = 1/(m2-m1), d = m1/(m2-m1)
or (m1/m2) = d/(d+1) -----------(b)
equating (a) and (b),
d = sqrt(1/2)
or total distance traveled is 1+2*0.707 ~ 2.4

hi freinds heres a puzzle for u

Theorem : 3=4
Proof:
Suppose:
a + b = c

This can also be written as:

4a - 3a + 4b - 3b = 4c - 3c

After reorganising:

4a + 4b - 4c = 3a + 3b - 3c

Take the constants out of the brackets:

4 * (a+b-c) = 3 * (a+b-c)

Remove the same term left and right:

4 = 3

johntony the flaw lies in your multiplication. You are multiplying both sides by zero.

2*0=0

then is it logical to say 2 =3 just because 2*0=3*0=0.

Theorem : All numbers are equal to zero.

Proof: Suppose that a=b. Then
a = b
a * a = ab
a * a - b * b = ab - b * b
(a + b)(a - b) = b(a - b)
a + b = b
a = 0

And Furthermore if a + b = b, and a = b, then b + b = b, and 2b = b,
which mean that
2 = 1

Sir ,
this is the last step in your proof:

4 * (a+b-c) = 3 * (a+b-c)

But you started with the assumption a+ b = c .

So do you realize what you are actually doing?

You are multiplying both sides by zero and equating the result.

And always remember a common factor can be cancelled only when the factor is non zero.

I'll show how 1 = 2 can be proved .

Assume a=b

square both sides

a**2= b**2

subtract ab from both the sides

a**2-ab= b**2-ab

substituting a=b in RHS

a**2 -ab = b**2- a**2

a(a-b)= (b+a)(b-a)

now again a =b .

cancelling out (a-b) (notice the folly . I repeat a common factor should be cancelled only when it is non zero. here a-b cannot be cancelled )

a = b+a
or a =2a
or 1=2.

I hope I have made things clearer sir.

And I will tell why urs is a case of incorrect reasoning.

Almost all of ur cases involve cancelling out terms that are numerically equal to zero, as per assumption.

Quote:

4 * (a+b-c) = 3 * (a+b-c)
Remove the same term left and right:
4 = 3

You arenot simply removing the terms. Actually wat we do, when we say cancelling is divide both sides of "equal to" sign by the same quantity. In our case it is zero. In mathematics, dividing by zero is simply not allowed . Because it only leads us to a trivial solution, because there isnt any unique, determinate number q such that q X 0 =0. Moreover, ur arguement technically involves dividing zero by zero, which is indeterminate.

So couple of ur fallacies are wat they are, false you would like to check into this link, to learn more about mathematical fallacies

I will try to come up with explanations for couple of other fallacies too, but later . the dollar question is quite curious. The explanation is curious too

The dollar question is also simple.

0.1$**2=0.01 $^2

and not 0.01 $ as john tony qrote.

0.01 $^2= 0.01 *100C *100C= 100C =1 $

As simple as that.

gokul prathap, the solution becomes much simpler using relative speeds and relative distances

marching rate of column = m1
marching rate of soldier = m2
distance where the first soldier meets the second soldier = d from the starting point
time taken to meet the last soldier = t
time taken to join the ranks after delivering message = t1
the relative speed of the soldier before delivering message = m2+m1.
relative distance covered before delivering message = 1 mile
relative speed of the soldier after delivering message = m2-m1
relative distance covered after delivering message = 1 mile
thus, t = 1/(m1+m2), d = m2/(m1+m2)
or (m1/m2) = (1-d)/d -----------(a)

t1 = 1/(m2-m1), d = m1/(m2-m1)
or (m1/m2) = d/(d+1) -----------(b)
equating (a) and (b),
d = sqrt(1/2)
or total distance traveled is 1+2*0.707 ~ 2.4

Thats simple.

yeah I agree with you Nerd. I don't want to discourage you Tamizh but believe me you can prosper in a much better place. Try to get into some other organisation like juno,DE Shaw ( If your interests lie in software) .They pay very well and also I heard from my friends the work is challenging too. This is how I advise my younger brother too. He is a very brilliant person ( topper at school) . But he never listens to me. He is wasting his talents in a 'dubukku' mnc. The problem with big organisations like TCS is there are so many people and I feel it is difficult to standout and make our presence felt. IMHO the smaller the better.

thanks nerd, mgb and rocketboy for ur concerns abt me

nerd, a special thanx for ur concern . my aim doesnt lie with TCS alone Mainly I took it bcoz as mgb said, just not to miss on an oppurtunity. definitely I am looking beyond TCS, dont want to be counted among a herd . In our college ppl can attend certain companies ( those that pay more than 4 L per annum) even if they are already placed. I may try few of them. Even if I miss, I have plan B

And currently my skills are concerned with networking and system administration. And I am looking forward to shine in data encryption, network security and ethical hacking domain. I hope, if i get into these fields, I can challenge myself intellectually. For all these, I thot TCS wud be a gud launch pad. Infact, I skipped two companies and waited for TCS .

Rocketboy, I am not into programming but I know a little bit of programming. I may require certain programming skills to shine in the abovementioned domains, so I will develop those skills shortly , and as I said companies like DE shaw are still within my aim . mgb, thanx. u spoke my mind

A second younger family member came and told the boy that what he is observing was already there for a long time. The boy got confused even further by the answer and started to get irritated. A third younger family member came and told the confused and irritated boy that what he is observing, did not exist there before, but someone from outside deliberately placed it there for all of us to find out, who?

There are 100 cans of wine. Some random guy mixes poison in one of the cans. There is a party in an hour. The poison is a slow one as in it takes 45-50 mins to kill a person. The king has many servants who are ready to do anything. How many servants will be needed to taste the wine cans so that the poisonous one can be found out within an hour ??

The cans are very big barrels and only one can is needed for the party. A servant can taste from one of the cans. If he is alive choose that can. If he dies, you can choose any other can from the remaining ones. So, only one servant will be needed.

since there isnt any upper bound for the no. of servants, we can use one servant per barrel and get the result in 50 mins. but i am sure, there must be a better solution, will look for it

Nerd,

TV's answer is also right because you have not asked for the minimum number of servants.
My answer was 33 servants but I did not like the king using servants instead of animals.

Each servant is given 3 cans. He tastes them at t, t+5 mins, and t+10 mins. t is an hour before the party.
If a servant dies between t+45 and t+50 the first can given to him is poisonous, between t+50 and t+55 the second can is poisonous, and between t+55 and t+60, it is the third can. If noone dies the remaining can which is not given to any servant is poisonous.
But if a servant dies exactly at t+50, or t+55 then we need to change the answer.

Nerd I have an answer but was just too busy to think it through throughly Okie heres my try..
I think the task would take 50 mins and 50 servants.Each servant tastes from 2 bottles plus a sip from 2 bottles tasted by 2 different servants.Lets say
bottles 1 & 2 have been tasted by servant A,
B tastes bottles 3 & 4,C tastes 5 & 6 plus 1 and 3.
This way..when 2 servants become sick at the end of 50 mins,we can pick out the bottles,just by looking at the common bottle between them.Am I close nerd or do I need to think more on it?

Nerd,

I was trying to find the minimum number of servants used and also minimum number of servants killed. In that case the answer is 33, and only 1 servant will die. If more than one can die, then the answer is 20 servants, and 2 will die (10 rows, 10 columns, 10 servants for the rows, and 10 for the columns).

If more than one can die, then the answer is 20 servants, and 2 will die (10 rows, 10 columns, 10 servants for the rows, and 10 for the columns).

7 servants. 2**7=128.
Making use of just 7 binary digits any number between 1 and 127 can be represented. 100 falls very well within the range.
servant 1 drinks from can 1 (1)
servant two drinks from can 2. (1 0)
servants one and two drink from can 3. ( 1 1)
servant three drinks from can 4 ( 1 0 0)
and so on.

At the end , say servants 1,3,4 and 6 die. Then the binary equivalent of the can no should be 101101. (0 for alive and 1 for dead) or in base 10 it is 32+8+4+1=45th can.
suppose can no 10 is poisoned. then it would have been consumed only by servants 2 and 4 (1010).

You are allowed to enter the room only once, and once you are inside the room you need to determine which lightbulb corresponds to which switch & once you open the door to the room, you must enter it. So how will you find out about the switches ?

Ramky,

Turn any two switches on and wait for 15 minutes. Now turn one of the switches off, and enter the room. The bulb and the switch that are on can be easily found out. Now touch the bulbs that are off. The hot bulb will be the one that was switched off before you entered the room.

7 servants. 2**7=128.
Making use of just 7 binary digits any number between 1 and 127 can be represented. 100 falls very well within the range.
servant 1 drinks from can 1 (1)
servant two drinks from can 2. (1 0)
servants one and two drink from can 3. ( 1 1)
servant three drinks from can 4 ( 1 0 0)
and so on.

At the end , say servants 1,3,4 and 6 die. Then the binary equivalent of the can no should be 101101. (0 for alive and 1 for dead) or in base 10 it is 32+8+4+1=45th can.
suppose can no 10 is poisoned. then it would have been consumed only by servants 2 and 4 (1010).

one more puzzle of similar type.

A man commits suicide by consuming poison. A detective is hired to find out the means of suicide. There are 150 glasses on the table filled with wine. apparently one among them is poisoned and the detective doesnt know which one. So they rent a poison testing setup. The detective wants to do the tests as soon as possible to reduce the rent charges and no more than one sample could be tested at the same time. So wat would be the best method for the detective to carry out the test as quickly as possible?

Poem Puzzle

I am first in everything,

I am not in difficulty,

I am never in war always in peace

I never get in bad company,

I always end a dialogue,

I always finish the game.

I am always in your dreams,

And though I am silent in love

I am the centre of honesty, and the end of all trouble.

I always come in time, and am never out of money.

But if I wouldn't come after u, it wouldn't be true.

So start with me and end with me or else - there's no escape.

Now find Who am I ???

1 1 1 1 1
2 2 2 2 2
3 3 3 3 3
4 4 4 4 4
5 5 5 5 5

Lets split the horses into five groups A, B, C, D, E. The above table shows the results after five races.

Now race A1, B1, C1, D1, E1 - U ll get the fastest horse.

You can omit the last two horses now.. Now race Two remaining first horses (those which participated in the second race, 3 seconds ). First and second of this race is the second and third fastest respectively !!

Ramky Anna,
What is the answer for your puzzle?

TV,
Very good puzzle! Nerd, 7 races is the right answer. But the horses that run in the 7th race in your answer are not correct. The remaining two first horses in the 6th race, the second, and third horses from the fastest horse's group (because the third horse from this group could be faster than the second horse from the 6th race), and the second horse from the group to which the second horse in the 6th race belongs. (enna Visu dialog maathiri irukka?).

Let us assume that A1 is the fastest horse, and B1, and C1 are the second and third horses in the 6th race. Then the horses in the 7th race will be A2, A3, B1, B2, and C1. How do we know whether B3 runs faster than C1 or not, without including it in the 7th race is

Gr8 answer TOS . Nerd, you were 90% correct

Lemme put this in my language . We discard any horse that is slower than any 3 horse. And by this virtue the horses in groups D & E are disqualified. Now C1 is already known to be slower than two horses (A1 & B1) from race 6. So horses slower than C1 (C2 to C5) are discarded automatically. Likewise it is impossible for B3 to be among top 3. So B3 to B5 are discarded. A4 & A5 are also discarded for the same reason. Now 6 horses remain in contention. Since A1 is undoubtedly the quickest horse there is no point in running it again. So the 7th race we run (A2,A3,B1,B2,C1) to determine horse number 2 & 3 .

OK, actually the previous question was just a preamble to the following puzzle.

In a similar situation as stated before, device a strategy to pick the quickest 5 horses out of 25 horses in minimum number of races. Again one can run only 5 horse at a time and there is no time measuring device.

I have just heard the question. And I dont know the correct answer. I and my friend cracked it in class, and I am not sure wether my answer is right. So I thought I will cross-check my solution with the big brains here .

Unlike choosing 3 horses, here we can give a range for answers I think.

c this case.

Conduct first 6 races similar to the previous one.

Now conduct the 7 th race with A2, A3, A4, A5 and B1.
If B1 comes 5th, v can straight away say A1, A2, A3, A4, A5 are the quickest horses, right? Or am I missing some thing.

So the answer shud be 7 to 9 races.

The mirror actually shows an uninverted person. We think the image is inverted because, when we see a person standing opposite to us, we see his left hand in our right side. So do we expect, when we face a mirror. But it doesnt revert. If you raise the left hand the image raises the left hand only. Only from a human point of view, it is a right hand and so inverted.

Suppose if we hold a pencil horizontally, with lead end in the right side, then according to ur answer, the lead should appear in the left side of the mirror, but it doesnt. Hope the answer is clear .

I am not sure TOS, but we both may be saying the same thing .... As you said, our left side is mirror's right side, when we assume the image is facing us. The keyword here is "assume". It is a matter of human perception. When we say someone is facing us, it implies that he has made a 180 degree turn about a vertical axis with respect to the direction that we are looking at . So when there is a rotation about y axis, only the x co-ordinates gets inverted. left becomes right and vice versa, but the top and bottom remains as such. All these because of the assumption that the human being, instead of standing along with us and instead of looking at the same direction as we do, has turned 180 degrees to face us. I will later tell the scenario underwhich such perception might differ.

And you were right to point at the paper and margin analogy.... it shows that this inversion is not a characteristic of mirror but of our perception. Any object facing us, we tend to feel that left and rigt are inverted.

To nerd,
Now imagine a world in which gravity is horizontal .... since it doesnt make sense, let us say we are all creatures hinged in a horizontal plane just like a swing mirror. And let us assume that our body is symmetrical about a horizontal axis and our eyes are placed symmetrically w.r.to the horizontal axis, or atleast placed "on" the axis (Very important for the conclusion). Then, to our knowledge, the only way in which another fellow can face us is by rotating about the horizontal axis. And since top and bottom are similar (symmetrical) we may feel that the person facing us is inverted in the vertical direction. In such a world, all inversions will only look like vertical inversion.

And we can see the analogy of this imaginary world with our real world. We are symmetrical about vertical axis. We can only rotate about vertical axis. And our eyes are placed symmetrically on either side of the axis of symmetry.

Hope this reasonging is conclusive. Nerd, please dont tell that this is reasoning no. 51

First, 9/12 = 0.75. Now we can construct 0.25 as 1/4 = 17/68 = (2*5+7)/68 = 5/34+7/68. So,

From: thamizhvaanan on Sat Aug 19 1:44:05 2006. [Full View]

OK, answer for the 25 horse race puzzle ( not sure if this is right)

As with the previous discussion, we conduct 6 races and the results are ordered according to the previous scheme.

A1 B1 C1 D1 E1
A2 B2 C2 D2 E2
A3 B3 C3 D3 E3
A4 B4 C4 D4 E4
A5 B5 C5 D5 E5

In a similar fashion, we can eliminate horses that are slower than any 5 horse. So after 6 races, we are left with 15 qualified horses, out of which one is an outright winner. Now for the 8th race, we run horses A2, B1, A3, B2, C1.

A1 B1 C1 D1 E1
A2 B2 C2 D2
A3 B3 C3
A4 B4
A5

Out of this, top two qualify as the horse number 2 & 3. And the horse that comes fifth and all the horses slower than that are disqualified. Likewise, horses slower than horse that comes fourth are also disqualified. This leaves us with 4 qualified horses in the best case scenario (when C1 comes last) or 7 horses in the worst case. This should take an additional one or two races. So, the number of required races will be from 8 to 9.

a question somewhat similar

There is a class of strength 60,every student in the class being very honest,very clever,very intellegent.The teacher comes in,and marks either blue or red color on the back of each student,students being unaware of the color behind them,and no one left uncolored and with at least one student being colored either red or blue.
After coloring each student ,the teacher leaves the class.
Now students can roam inside the class,notice the color behind any other student but cannot inform him about his color.
Now-
The teacher walks in every hour and asks "Those who are sure about blue color behind them may come out of class!"
p
So the question is --
How many students will come out at 1st hour

How many at 2nd hour?

|How many at nth hour? </B.

Did anyone find the answer to this??
I remember reading a similar question on the net...

From: Sonata on Wed Aug 30 18:29:36 2006. [Full View]

The answer to this is as below:

let n be the no of boys be marked blue

Now suppose only boy is being marked blue i.e n=1 , then that boy does not see anybody else marked in blue and hence he comes out in the first hour.( remember that at least one student is colored either red or blue)
i.e if n= 1 , one boy comes out during the first hour and thats it.

now if n=2

Both of them who are marked blue get to know that there is already one boy who is marked blue.
But both of them do not come out in the first hour as they think that it is only the other boy who has been marked blue.

Now since the other boy does not come in the 1st hour, they come to know that there is another boy who has been marked blue but since they do not find anyone else, they get to know that it is none other than themselves and both of them come out in the second hour.

i.e if n=2, then two come out in the second hour.........

if n= 4,

each one of the boys marked blue know three other boys who are marked blue,but if in the third hour none of them come out then they get to know that there is one more who has been marked blue.But since thay can find only three they conclude that they have been marked blue and hence all the four come out in the fourth hour...

Similarly it works out that if there are n boys marked blue, then n number of them come out in the nth hour.

Sorry Sonata i am not able to follow your argument. Why should the realization dawn upon them only in the nth hour? why not earlier?

even if the no of students n=2 , if one person doesn't make a move the other person realizes instantly that the color on his back is blue and steps forward. Sensing this hesitation the other guy who was not prepared earlier seperates from the cluster. So practically both the students leave the class in the 1st hour itself.

I think the solution is correct only one mistake is that, if n=1, the odd boy comes out immediately, if it is 2 both of them come out at the end of 1st hour as you said. but the fact remains that, no matter how many boys are painted, all come out in the same hour in a single set and not as seperate groups as suggested. If 3 boys are painted, all of them comes out in the 2nd hour.

Remember that "the teacher walks in every hour and asks "Those who are sure about blue color behind them may come out of class!"

So here 1st hour is when the teacher calls out for the 1st time and I assume that the students

1)should come out immediately once the teacher calls and
2)that they won't come out until the teacher calls ...

ofcourse, with every passing second, one is shifting his position w.r.to a static co-ordinat, due to earth's rotation as well as revolution. So, if Jim is going to go around Bob (depending on how big Bob is ), he is going to take some time. Meanwhile, both of them would have shifted from their previous point .

OK here goes the first inference in my question set. First question says:

What is the sum of all integer solutions in this question set? (including this number and added in a non-recursive manner) (integer answer)

It means that the 1st answer is added to the sum of the rest of the answers, but still it gives 1st answer as the solution. So, the sum of the rest of the integer solutions must be zero. This is the first inference.... proceed in a similar manner

8.What is the answer to question 1 divided by answer to question 8?(Integer)

If X is the answer to Q1 and Y, the answer to Q2, then X/Y = Y which implies that X = Y^2, a square number. Y can be either negative or positive.

clue no.3:

Quote:

6.What is the average of all numerical values in this question set? (including this number)(Integer)

Sum of all the integers is X (the answer to Q1). So the average is X divided by either 5 or 6 (depending upon wether answer 10 is an integer)

So X is a square number divisible by either 5 or 6. So minimum X can be 25 or 36

So, for the sum of the rest of answers to be equal to zero, there must be atleast one negative number. That is because the answer to question 5 is definitely positive and non-zero (it can be only 1,2 or 3).

Now apart from question 1, there are 4 probable integer answers, out of which 3 are definitely positive ( questions beginning with "how many"). So, answer 8 must be definitely negative.

Let us assume that there are only 5 integer solutions and 10th answer is a non-integer. Then it means that answer 8 must be negative number big enough to cancel out the positive answers 2, 5 & 6.

Then A8>A6 ==> X > X^2/5
which implies, X < 5... which is against
Quote:

So X is a square number divisible by either 5 or 6. So minimum X can be 25 or 36

So, Answer 10 should also be an integer, and negative to bring down the sum of rest to zero.

So, Answer 6 is X^2/6 and X^2 is a number divisible by 6. A few more steps, you will get the answer

Let's denote answers each question as A1,A2,....,A10. For simplicity, let's assume A10 is an integer. (I'll show you how to deduce that later.)

(i) Q1 implies: A1+A2+A5+A6+A8+A10 = A1

i.e. A2+A5+A6+A8+A10 = 0

which means that at least one of these 5 is negative. Therefore,

A4 = False

(ii) Q6 implies: (A1+A2+A5+A6+A8+A10)/6 = A6

Since, A2+A5+A6+A8+A10 = 0. We have

A1 = 6*A6 ---- (Observation. 1)

(iii) Q8 implies: A1 / A8 = A8

i.e. A1 = A8 * A8. Since A8 is an integer,

A1 is perfect square. --- (Observation 2)

Together with Obs-1, this means that minimum value of A1 is 36. Let's use this and try:

A1 = 36

By Obs-1, A6 = 6

Now Q8 tells us, A8 = +6 or -6 (Note: both are valid) ---- (Observation 3)

(iv) Note that Q2,Q5 are 'how many' type questions. So their answers A2,A5 can take values like 0,1,2.... only.

Let's look more closely and see their lower and upper bounds.

There are only 4 True/False questions. And, A4 is already False. So

0<=A2<=3 --- (Observation 3)

Now, A5. Q5 is an interesting question. Read this carefully: Can the answer be 0? NO! Simple because it means there can be no answer 0 , and contradicts itself. So, A5>=1. There are totally 6 integer answers, so A5<=6. Further look reveals that, A1 cannot be counted since it's greater than 6. So,

1<=A5<=5 ---- (Observation 4)

(v)

Recall that A2+A5+A6+A8+A10 = 0.

With what we know,

A2+A5+A6+A8+A10 >= 0+1+6-6+A10 (by plugging in the lowest possible values)

i.e. A2+A5+A6+A8+A10 >= 1+A10

If A10 were zero or positive, note that it's impossible to get 0. So

A10 has to be negative. ---- (Observation 5)

(Here you can also see that, without assuming A10 is an integer, we have no way to get 0. So A10 should be an integer and it has to be negative.)

Can also reason that A8 is negative and hence A8 = -6.

Now can also conclude A1 is largest value here. So answer to Q3 is true.

A3=True

This implies that A2 is at least 1. So we can rewrite Obs-3 as,

1<=A2<=3 ------ (Observation 6)

(vi) Let's go back to Q5. Recall by Obs-4,

1<=A5<=5

From what we know so far, we can eliminate 3, 4 & 5 as answers. (We can't get that many equal values!). Only 1 & 2 are possible.

Let's try A5=2. Now we need another 2 as answer so that there will 2 equal values. It turns out that we may only have that for A2, because all others cannot have 2.

Now what does A2=2 mean? It means there are two True answers. We already know that A3=True & A4=False. So either A7 or A9 (not both) has to be true.

But, A7=False since A2=A5. So A9 has to be true. i.e.

A6 = |A2-A5| - (A8*A5)

which is of course false.

A contradiction! So

A5=1.

Now A2 cannot be 1 (as this means 2 equal answers), and so A2>=2.

This implies A7=True. And, obviously

A9=False

Therefore,

A2=2.

Now to get A2+A5+A6+A8+A10 = 0, we must have

A10 = -3

Done!

Well, that's just the idea.

In Second quiz, the new Q7 is such that it can never be true so you have to try to make A9 true. Accordingly the integer values will all change.
