Who Said What? (Posted on 2007-05-17) Difficulty: 3 of 5
You are in a popular tourist town in the land of Liars and Knights. You happen to overhear a conversation another tourist is having with three of the locals: Alex, Bert and Carl. Each of the three could be a knight, a knave or a liar. You know that for each question the tourist asks, Alex, Bert and Carl each give one response, but you don't know who said what. The conversation is as follows:

  1. What type are each of you?
    • I am a knight.
    • I am a knave.
    • I am a liar.
  2. How many of you are the same type?
    • We are all the same type.
    • We are all different types.
    • Exactly two of us are the same type.
  3. What type is Alex?
    • A knave.
    • A liar.
    • Different from Bert.

Can you determine which type Alex, Bert and Carl are?
