Brain Teaser

[dimava]

A very rich farmer was getting old, so this kid wanted a job, so the farmer said:

I can pay you in 2 ways:

1 way: $10,000 for the whole month
2nd way: Every day I'll double how much I pay you, and the first day you get 1 penny.

which is the smarter way

and how much is the diffrence?

[Sam Finch]

The first way he gets $10,000

The Second way he Gets

$42949672.95 = (2^32)-1 cents assuming it's a 31 day month

so the second way is better.

[dimava]

acctually I got $1,000,000

here's another one:



I guy goes to this town. the whole town only has 2 hair dressers (next door) Hair Dresser # 1's hair is nicely cut and he looks good.

Hair Dresser #2's hair is very long and un staright and looks ugly and is really weird. Now to which one would you goto to get your hair cut?

[Iain17]

Actually i think it is "$21474836.47" for a 31 day month

[Edited by Iain17 on 08-24-2000 at 05:29 PM]

[Iain17]

#2, cos he must have cut #1 hair, which looks good.

[dimava]

I was thinking of a 30 day month, and Can anyone answer the second brian teaser?

[dimava]

correct Lain17

another one:


I guy lives on the 67th floor, every morning he goes to work, so he takes the elevator all the way down. but when he comes home, he takes the elevator to the 60th floor and then walks up 7 floors to his apartment, why does he do that?

[Sam Finch]

Because he's too short to reach the button for the 67th floor, he can only reach up to 60.

[dimava]

correct again


what weighs more a whale or a elephant?

[Sam Finch]

Usually an Elephant, because the whale is probably in the sea and weighs very little due to boyancy.

[dimava]

acctually 16 elephants wiegh as mush as the whale's tougue alone

[Iain17]

Ok I got one for you then.

You are trapped in a castle. There are two (2) exits. One of the exits leads to certain death, and the other leads to freedom.

There are two guards standing by the exits. One always tells the truth, the other always lies.

You do not know which exit is the right one, and you don’t know which guard tells the truth and which one lies.

You have one (1) question to find out which door leads to freedom. What is the question?

[dimava]

here's another one:

pretend that you are the driver of a train.

you have 8 cars, in every car there are 8 blue seats and 9 red seats. 3 out of every 4 cars have bathrooms. the remaining have small bed room cabins. Now on every 2 of 6 cabins, they serve food 5 times a day (including snacks) and on the remaining 10 times a day.

so there are 3 drivers of the trian... one is 23 years old, the other is 25 years old, how old is the third one?

[dimava]

lain, lets not start that over again

[Sam Finch]

Ian
check the other thread for a detailed discussion of the question.


dimava

You asked which weighs more, not which is more massive, somethings weight is how mugh force it exerts downwards due to gravity, which is nothing for the whale because it is floating.


Actually this is technicly wrong, but I assumed that it was a trick question and this was what you were getting at.

[dimava]

ok, thats old now try to figure this one out:




pretend that you are the driver of a train.

you have 8 cars, in every car there are 8 blue seats and 9 red seats. 3 out of every 4 cars have bathrooms. the remaining have small bed room cabins. Now on every 2 of 6 cabins, they serve food 5 times a day (including snacks) and on the remaining 10 times a day.

so there are 3 drivers of the trian... one is 23 years old, the other is 25 years old, how old is the third one?

[Iain17]

as old as i am

[Sam Finch]

I'm 20, thanks for asking.

OK, there's a knockout football competition, 584392 teams enter, the rules are that when 2 teams play each other the winning team goes through to the next round and the loosing team goes out and doesn't play any more, if the game is a draw (tie) then it is decided by flipping a coin. Excluding byes how many matches are played?

764.455361679149974944550955626574

[dimava]

its 169 I used this code:

Dim A As Integer
Dim B As Single
Private Sub Form_Load()
B = 584392
Do
B = B / 2
A = A + 1
Label1.Caption = A
Loop Until B = 0
End Sub

[Sam Finch]

I askes how many matches not how many rounds, you don't need any code or a calculator.

[dimava]

oh..... 292196 right?

48699? or 340895?

[Sam Finch]

no and no.

[Illuminator]

SUM (584392 / (2^r))

where r= 0 to number of rounds or log(584392)(base 2)

[Sam Finch]

nope, remember there could be some byes 584392 isn't a power of 2, so that won't work, you don't need a program or anything, a 7 yearold could do it in his head.

584390 or 58439

[Iain17]

584391

[Sam Finch]

Congratulations, shower yourself with incredible prizes.

The two door problem. Try one of the following questions directed to either man.

"If I asked your companion, what door would he tell me to use?" Liar will lie about the truth tellers's response. Truth teller will tell truth about liar's response. Either will indicate the wrong door: Take the other door.

"If I asked you: Which door would you say is the good one?"
Truth teller will obviously give correct answer. Liar must think as follows: "If asked, I would haven given him a bad answer. I must lie about what my answer would have been, so I have to point to good door." Both men will indicate the good door.

How about this one:

Once about a time the where 3 young men hitchhiking across the nation. One day they couldn't get any lift. It became dark and it started raining so the 3 men tried to find some shelter.

They found a farm nearby and they asked the farmer if they could spend the night in his barn.
The farmer said "Allright, but you have to pay me 10 coins (I dont remember the currancy of this nation) each"
The men did so and went to sleep. Early the next morning they where on there way again.

Then the farmer thought that he might have charged them a bit to much. So he gave his son 5 coins and told him to run and catch up with the three men and give the coins back to them.

The son did run to the men but he only gave them one coin each and kept two for himself.

Now the three men have paid 9 coins each which add up to 27 and the son kept 2 so that makes a total of 29. But they paid 30 to start with so what happend to the last coin?

[Iain17]

3 * 10 = 30    intial outlay
30 - 5 = 25    farmer has 25 coins, gives 5 to son
5 - 3 = 2      boy keeps 2 coins, each man gets one back.

Maybe an explanation

You are talking absolute rubbish at the end. 3 * 9 does = 27. But the boy does not get two coins on top of this. His two coins are taken from the 27 already paid. This leaves us with 3 from the original 30. So each man has there coin back.
