Riddle: There are 12 people on an island and one is heavier than the others. You have to figure out which Islander is the heaviest using a seesaw. But you can only use the seesaw 3 times. How do you figure out which one is heavier?
Answer: First, you do six and six. If one of the six is heavier, then you do three and three. Then if one of the three is heavier than you do one and one. If the second or first one on the seesaw on heavier, than that is the answer. But if none of them are heavier then you know that the one that is not on the seesaw is heavier.

Riddle: A man is sitting in a room along with a group of mostly women.
