 Ask for help (Posted on 2005-07-05)
You are on a treasure hunt, wondering where the "Truth Treasure" is buried. You have no idea where it is buried, so you go Truth Town (made up of only Liars and Knights) because it is famous for holding the treasure's secret location.

When you enter the city, you see two twins and they know each other's types, but you don't. One twin says "(Exactly) one of us is a Knight..." and the other twin says "...and (exactly) one of us is a Liar." You can only ask one question and only to one person. You only care about where the treasure is kept, and obviously a liar would give you a wrong answer, so what should you do?

The two twins say the same thing, so they are of the same type. Therefore, their statements are both false, so they are both liars. You can ask, "Where is the treasure not at?" A liar would tell you where the treasure is at.
