Are you smart enough?
The Two Riddles
You are on a small forested island surrounded by sharks. A fire has started on the northern side of the island. The wind is blowing from north to south, and the fire is spreading. You cannot get into the water, or else you will be supper for the sharks. You also have no boats. How do you save your skin?
There are four men and there are four hats, two blue and two brown. Each man is wearing a hat, but for some odd reasons (for the sake of the riddle) he cannot see the colour of his own hat (which is either blue or brown) nor takes it off his head. Three of the men stand each one behind another facing a wall. The man furthest from the wall sees the two men in front with their hats. The middle man sees only one man with his hat in front. The man nearest the wall sees only the wall. The fourth man is on the other side of the wall, and he also only sees the wall.
They are trying to find out the colour of the hat he himself is wearing. Which man is the first to know the answer? You must arrive at your answer by logical reasoning.
