I've got a good math riddle. Either it will take you like, 5 minutes...(like it did me.) Or it could take a day or even longer to figure it out. (like it did everyone else in my highschool math class.)
You have 10 stacks of coins that each have 10 coins in each stack.
Each coin weighs 1 Kilogram. Except for one stack of coins that instead weighs 2Kilograms each.
You have a scale, however you can only use it once.
How do you figure out which stack has the coins that weigh 2 Kilograms?
