Here's another Puzzle (Charlie, you there??)
There are three bags of coins & a scale. Two bags contain real gold & 1 has fake. There is an unknown number of coins in each bag, but you do know one thing: a real coin weighs 1oz, and a fake weighs .9oz. Using the scale only once, determine which bag contains the fakes.
