You are locked inside a room that has only two doors. You know that one door leads to freedom and one leads to certain death but you do not know which door is which. Also inside the room are two guards, one standing at each door. You know that one guard always tells the truth and the other one always tells a lie but you do not know which is which.
You are allowed to ask one question and then you must open a door and go through it. You can choose which guard to ask the question to but can only ask it of one of them.
What question can you ask that will guarantee you will choose the door to freedom?
You need one guard to give you the other guard's answer. ask a question like, "If I were to ask the other guard which door leads to freedom, what would he say?"
If you ask the guard who always tells the truth, he would tell you the other guard would point you to the door of death. If you ask the guard who always lies, he would tell you the opposite door of the truth-telling guard and point you to the door of death. In either case, both guards will point to the door of death so you should choose the other one.
