have you seen Labyrinth (with David Bowie in a frightening codpiece)? I think this is in there...

On your trip back from the Island people to the deep dark forest, you get lost. A trap door suddenly opens and you fall down into a dark chamber.

You hear a voice, "You are trespassing and the penalty is death. In five minutes you will be buried alive. However due to our exceeding kindness and mercy, and because you were once ruler of the forest people, we will allow you to earn your life back. In this dark chamber there are two doors. You may choose to open either one - if you choose correctly, you will go free. If you choose incorrectly, well, instead of just being buried alive, you will be eaten alive by army ants.

To help you choose a door, you may ask a question. However, you should know that two people will hear you and one of them always lies and the other one always tells the truth. One of them will answer your question, but you will not know which one. Each of them knows which door leads to freedom.
Good Luck, you have four and a half minutes left."

What question do you ask to win your freedom? (At least two solutions.)

This is more like it...no bloody maths! Quite simple really, when you put a bit of thought to it, simply ask one of the guards: "Would he/she/it tell me that this door leads to freedom?" (Answer is in blue...)

If I were to ask you if this door led to my freedom would you say yes?

If I were to ask you if this door led to my freedom would you say yes?

The one that lied would say 'yes' and so would the one that told the truth, how does that decide your route for you?

To be honest with you, I'd have just stared in amazement at the codpiece.....

and then asked

"If I asked you yesterday which was the correct door, what would be your answer?" or "What would the other person/door say is the correct door?"

The one that lied would say 'yes' and so would the one that told the truth, how does that decide your route for you?

If it's the right door the trith-teller would say yes. The lie teller would say no, but will lie and say they would say yes.

If it's the wrong door the truth-teller would say no. The lie teller would say yes but will lie and say they would say no.
