Clue to Puzzle #49: Fork in the Road
49. You reach a fork in the road. A sign explains that in one direction is Heaven and the other is Hell. Each path is blocked by a Guard. The sign goes on to say that one of the guards will always lie and the other will always tell the truth, it does not say which guard is which. We assume that the guards do know which path leads to where.
You may ask one question of only one guard in order that you can determine, with certainty, the way to Heaven. What is that question?
You may ask one question of only one guard in order that you can determine, with certainty, the way to Heaven. What is that question?
So here the answer involves using the certainty that one is lying together with the certainty that one is telling the truth to obtain something that we know to be a lie.Unfortunately that is all the help I can give you without revealing the answer.
