1. A prisoner is told, “If you tell a lie we will hang you; if you tell the truth we will shoot you.” What statement can he make about the situation to save himself? (#5)

2. Eight BBs look alike but one is slightly heavier than the others. How can you identify the heavy BB in only two weighings on a balance scale? (#68)

3. Two mathematicians are walking down the street. The first says to the second, “I know you have three sons. What are their ages?” The second replies, “The product of their ages is 36.” The first says, “I can’t tell their ages from that.” The second says, “Well, the sum of their ages is the same as that address across the street.” The first says, “I still can’t tell.” The second says, “The oldest is visiting his grandfather today.” The first says, “Now I know their ages.” Do you? (#98)
