Question 15
Five friends discuss who ate Tony’s apple.
Denny: “It is not Tim. It is Mary.”
Mary: “It is not Harry. It is not Tim.”
Harry: “It is not Tim. It is not Denny.”
Hugo: “It is Harry. It is not Mary.”
Tim: “It is Hugo. It is not Denny.”
Exactly one of them told the truth. Who ate the apple? Enter the name.
Assume exactly one of these five friends ate the apple. A speaker tells the truth only when both sentences are true; each other speaker has at least one false sentence.
