Question: The warden of a circular jail is extremely hyper one day so he begins running around opening cells. The jail has 100 cells numbered from 1 to 100. He runs in a circle and opens all of the cells. Next he runs around and closes every 2nd cell (starting with cell 2, 4, 6 , etc.). If a cell is open he closes it and if a cell is closed he opens it. When he finishes running by all 100 cells he opens/closes every 3rd cell (starting with 3, 6, 9, 12 etc.), then every 4th cell (starting with 4, 8, 12, etc.) and so on. He does this until he goes around and only changes the 100th cell.
When he is done what cells will be open?
Answer: The cells 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100 will be open. Only the cells that have two of the same factors (4 = 2 * 2) will be open because they are opened and closed the same number of times (except 1 which is just opened). Since they have the same factor twice their number of factors is odd.

Question: Alex was the strongest man in the world. He can lift up something that weighs 1000 kg easily. He can even pick up five women at once without any pain. But one day, there was a Weight Lifting Challenge Show. All the top 5 strongest man entered including Alex. The challenge is that they each have to lift up a really heavy object which weighs 1005 kg for five minutes. The winner is who didn’t drop it until it reached the time. If they all did it, the judges will decide to give first place to a person who can lift it up easily and stand still with no trouble looking. If Alex was the strongest man, he’ll probably come first. But he came second instead when the challenge was over. Why?
Answer: Because he’s not the strongest man anymore. He used to be the strongest man. Read the first sentence again (Alex was the strongest man in the world). He was the strongest but someone is stronger than him now.
