Guest Posted February 16, 2008 Report Share Posted February 16, 2008 we have 10 boxes each box contain 10 cigarettes, each cigarette weight 10 grams, and one of these boxes weight 110 grams (each cigarette weight 11 grams). how you can know the different one? by using balance only for one time.

0 Guest Posted February 16, 2008 Report Share Posted February 16, 2008 could you just figure that out by first weighing each of them, then coming finding one of a normal, or average weight and the one with the slightly off weight, then using balance?
