Brain Teasers
Four Men
One day, a man in a coffee shop left his wallet filled with gold on the floor. Someone found it and asked who owned the wallet. Four men claimed it. If the men who don't have the gold are lying, and the one who has the gold is telling the truth, which one has the gold?
Bob: Joe owns the wallet.
Mike: I own the wallet.
Steve: Bob owns the wallet.
Joe: I own the wallet.
Bob: Joe owns the wallet.
Mike: I own the wallet.
Steve: Bob owns the wallet.
Joe: I own the wallet.
Answer
Mike owns the wallet. The way we can determine this is by looking at Bob's statement, which says Joe owns the wallet. Joe says he owns the wallet. If Bob is telling the truth, that means Joe owns the wallet, and Bob also owns the wallet since he is telling the truth. Since only 1 person has the wallet, Bob must be lying, and so is Joe. Steve also must be lying because he says Bob owns the wallet. Mike is the only one left, and he must be telling the truth.Hide Answer Show Answer
