Question: You have two coconuts and you want to find out how high they can be dropped from a 100 story building before they break. But you only have $1.40 and the elevator costs a dime each time you ride it up (it's free for rides down).
How can you drop the coconuts to guarantee you will find the lowest floor they will break at, while starting and ending at floor 1?
Note: They break when dropped from the same height and they don't weaken from getting dropped.
Answer: You could drop it at floor 1 first (because you start at floor 1). Then you would go to the floors: 14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, and 100. Whatever floor your first coconut breaks at, go to the floor above the last floor the coconut survived and drop the second coconut from this floor. Then go up by one floor until the second coconut breaks and that is the lowest floor it will break at.

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.
