Knaves! (Posted on 2012-05-21) Difficulty: 2 of 5
You meet three people, A, B, and C. One is a knight, one is a liar, and one is a knave.

A:I am a knave.
B:A is a knave.
C:I am not a knave.

Who is a knight, who is a liar, and who is a knave?

If A is a Knave, then all three statements are true, which can't happen if one is a Liar.  A cannot be a Knight, so A must be a Liar.  This means B's statement is false, so B must be a Knave.  This leaves C as the Knight.

A = Liar
B = Knave
C = Knight
