Friends and a WalletLogic puzzles require you to think. You will have to be logical in your reasoning.
You and your five friends, conveniently named A, B, C, D, and E, were hanging out when you spotted a wallet on the floor. You have a poor memory, but you remember that it is owned by one of your friends.
You: Whose wallet is this?
A: That's mine.
D: You're lying, A.
C: Yeah, A, you are lying.
B: A is not lying, guys.
D: That wallet is owned by C.
E: Yeah, D is telling the truth.
B: No, E. That's your wallet.
You remember that at least 2 of your friends always tell the truth (truthtellers), while at least 2 always lie (liars).
Thanks to your memory, however, you can't remember which friend lies or tells the truth.
Can you figure out who owns the wallet?
AnswerC owns the wallet.
B's first statement says that A is telling the truth that it is A's wallet. His second statement, however, says that it is E's wallet. The statements cannot be true at the same time, so B lied in both of them. B is a liar.
Since B was lying when he said that A is telling the truth, A is the other liar, too.
C and D are automatically truthtellers, since they both told the truth when they said A was lying. E is also a truthteller since he said that D told the truth.
Therefore, C owns the wallet.
