Puzzle #1: 10 Baggage of Cash

You could have 10 baggage; every bag comprises 10 cash. In 9 of the baggage, each coin weighs precisely 1 gram. Nevertheless, one of many baggage holds counterfeit cash, which weigh 1.1 grams apiece. You don’t know which bag comprises the false cash, and the burden distinction is just too delicate to really feel along with your palms. Fortunately, you might have a scale to assist. It shows a exact and correct numeric readout (for instance, should you positioned a raisin on the dimensions, it’d show: “.58 grams”). Not so fortunately, the dimensions’s battery is dying and after one use it can conk out. How will you determine the bag with the heavier cash utilizing solely a single weighing on the dimensions? You’re allowed to take cash out of their baggage, however you solely get to learn one quantity from the dimensions.
