brain teaser

[MR.?]

This question was given to my literature class.

Probably a few of you have seen this questoin before.
If you have......... give your answer and dont ruin the surprise.

This question was given to 2nd graders and graduate students at Harvard.

It tests your critical thinking ability. The 2nd graders answered the test faster and more acurately than the Harvard students.

Here it is:

Your locked in a room with a group of people. There are no windows, only a door.

This door is locked shut. The door can only be opened by pushing one of the two buttons on the wall.(button A &B).

The switches are connected to a explosive device. If you push the wrong button you will detiate the bomb.

There are two computer in the room(computer A&B). These computers will assist in determining what button is the correct one to choose.

!!!!!One of the computers will always tell the truth and one will always lie.....there is no way how to determine which one is the correct computer.

You have ONE question to ask ONLY ONE computer. If you ask the correct question....you will find out what button to choose without blowing up the room.

i know this may be easy for some of you...it took me 1/2 hour to figure it out.

i was bored....

liturature????

 

[lordfreze]

i would ask... are we going to die?

 

[WODIN]

Ask which switch is hooked to the bomb. Both will give the same answer.

THat would be too easy Scrappy....that's the point of the brain teaser....there is one right answer that is hard to come up with but will seem obvious when we hear it I guess.

 

[MR.?]

The question is written properly, and all the information needed..... I already stated

 

[booger]

Hmmm

Just ask either of the computers what the other computer would say in reference to the button that will detonate the bomb.

 

[MR.?]

Here are some hints.

* one will lie, the other will always tell the truth
---- this should help you choose your answer
* however, it doesnt matter which computer you ask
