Puzzle
You are given 9 identical bags of balls. Each bag contains 9 balls. Each ball has same weight, except all the balls in one such bag that are lighter than all other balls. Your job is to find the bag that contains the light weighted balls. You have a two plate balance but no weights to weight. How will you identify the bag that contains lighter balls if you can weight two times only.

Do you dare to try? Good Luck !
Make three sets of 3 bags each. Compare weight of 2 sets using dual plate weight.
ReplyDeleteCase 1:if both sets weight is equal, then third set contains lighter bag
Case 2: weight one set is lesslthan other, then that contains light weight bag.
Now once light weight set of 3 bags is identified, repeat same process by weighing 2 bags by putting one bag on each side of scale.
that's wonderful pick. Three cheers !
