  1. If you put half of the coins on each side of the scale, the lighter side is the one with the fake coin. Then you remove half of the coins leaving you with 15 coins. You put one coin aside and weight seven coins on each side, if the scale is even, you have found the fake coin, if not, the lighter side is the one with the fake coin leaving you with 7 coins. You put one coin aside and weigh 3 coins on each side, again if the scale is even, you have found the fake coin, if not, you are left with 3 coins. Now do I need to tell what to do?
