Who has the key? (Posted on 2002-05-17) Difficulty: 2 of 5
An adventurer found a locked treasure chest in a dungeon. He tracked down three brothers (each either a Liar or a Knight) one of whom has the key to open the chest.

Each made a statement:

  • A: I have the key to the chest.
  • B: I don't have the key to the chest.
  • C: B Doesn't have the key.

    The adventurer knows that at least one of the three is a Liar, and at least one - a Knight. Who has the key?
