Ask for help (Posted on 2005-07-05) Difficulty: 1 of 5
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?

they are both liars becuase the one that says that exactly one is a knight is lieing about just one being one and the other is also lieing about exactly one. if the 1st is the knight that makes the second a liar but that contradics what he says hed being lieing about there beinga  liar the if the 1st one was a liar then they are both one or the other, and then the other would be lieig about there being liars, so i say they both are and i would ask either one where the treasure was and assume that theyare lying, and look in the oppostie place i guess.
