During lunch hour, a group of boys from Mr. Bryant’s homeroom visited a nearby grocery store. One of the five stole an apple.
When questioned:
Jim said: “It was Hank or Tom.”
Hank said, “Neither Eddie nor I did it.”
Tom said, “Both of you are lying.”
Don said, “No, one of them is lying, the other is speaking the truth.”
Eddie said, “No, Don, that is not true.”
When Mr. Bryant was consulted, he said, “Three of these boys are always truthful but two will lie every time.”
Who took the apple?
Answer
Tom took the apple.
Jim, Hank and Eddie were telling the truth. Tom and Don were lying.
