You have bags of coins each. In all of them except one, every coin weighs exactly grams. The remaining bag is counterfeit: all of its coins weigh the same, either grams each or grams each, but you don't know which. You may take any coins out of the bags, and you have a digital scale that gives exact weights. Can you identify the counterfeit bag with just one weighing?
