Answer of the puzzle (You have 100 bags of coins each with 100 coins) is :
Take 1 coin from first bag, 2 coins from second bag, 3 coins from third bag and similarly 100 coins from 100th bag. In ideal case some of all these coins 1+2+3…. +100 should be 5050 ounce but the gold coin weights 1.01 ounce so whatever extra weight we get would tell us the bag number. for example if the total weight would be 5050.03 ounce, gold coins are in third bag.
