Golden coins. You have 10 bags of gold coins, 10 coins per bag, 10 grams per coin, but one bag of coins weigh only 9 grams per coin (because of low quality). How do you find out which bag contains low quality gold coins? You may use a scale only one time. This is a realy tricky one. I wont be supprised if you end up in rage and furious anger. p.s Thank you Nevins for this one

empty bag 10 put 1 coin from bag 1 into bag 10. put 2 coins from bag 2 into bag 10 put 8 coins from bag 8 into bag 10 etc. now u can see how many grams u miss, if its 5 grams, bag 5 was gay. EDIT: if you dont miss anything, its bag 10
