You will hang me. If they hang him, then the statement was true and they could only hang him for telling a lie. If they shoot him, then it makes the statement a lie and they were only to shoot him for telling the truth. An alternate solution is to say, “You will not shoot me,” leading to the same quandary for the killers.
During lunch hour a group of boys from Mr. Bryant’s homeroom visited a nearby grocery store. One of the five took an apple.
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.”
Tom took the apple Jim was telling the truth Hank was telling the truth Tom was lying Don was lying Eddie was telling the truth (three telling the truth and two lying)

Four cards are placed in front of you on the table, each with a number on one side and a color on the other. The visible cards show 3, 8, red and brown. Which cards should you turn over in order to test the truth of the statement that if a card shows an even number on one face, then its opposite face is red?
You’d need to turn over only the 8 and brown card. Only a card with an even number on one face and which is not red on the other face can invalidate the stated rule. If you turn over the 3 card and it’s not red, it doesn’t invalidate the rule, nor does turning over the red card and finding it has the label 3.
