quote:Originally posted by LaithIf there were two separate rooms, one with 3 switches (where you are standing) and one with 3 light bulbs, you are allowed only one entry in the other room, how could you find out witch switch belongs to witch light bulb?

quote:Originally posted by LaithOkay that was easy for you guys, here's another one:There are 2 roads, one going east and one going west, and only one of them leads to the right place. There is a house in the middle with 2 people inside; one only speaks the truth and one only lies, How can you know witch direction to take if you only can ask one question? (you dont know who will answer the door)Laith

quote:Originally posted by harryneildOk lets see if the brain boxes of this forum know the answer to this puzzle!You have died and before heaven there are two identical doors. In front of each door there is a guard. Both guards are identically looking. The one guarding the door to heaven will always tell the truth. The one guarding the door to hell will always lie. If you can ask them 1 question which they both answer, in order to find out which door is which, what do you ask them?Harry Eakins"Knowledge has to be improved, challenged, and increased constantly, or it vanishes."

quote:Originally posted by another_someoneIt is an old question, with a number of variations.The solution is fairly straight forward.Regard the two guards as logic circuits, one will invert the answer, and the other will give a positive result. If you feed a response through both circuits, you will get a single negation (this is true no matter which order the response passes through).Thus you ask one guard what the other guard would have said (thus, either the first guard will invert the answer, and the second will just pass the answer through; or the first guard will pass the answer through, and the second will invert the answer; in either case you know the answer will have been inverted only once).This if you ask one guard to tell you what answer the other guard would have told you, you know that the answer you will get is the exact inverse of the truth.George
