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?

a verty long solution | Comment 35 of 41 |
they are both liers coz y wud the liar say 1 waz a lier or a knight he would say the opposite so if the 1st 1 waz a liar either none or both are knights. and if the 2nd is the liar then either both or none are liars so 1 is definatley liyin so coz they are twins an thery say different things i think they are both liers and so if you say 'where is the treasure not bueried' they would have to say were it waz bueried or they would be telling the truth so u wud go were they sed it waznt of course if 1 told the truth u wudnt get very far if u askd the 1 who told the truth so this is a bit stupid coz i dont realy think there is an answr
