There are 8 boxes each containing 8 marbles. There are two kinds of marbles – Brazilian kind and Indian kind. Each marble of the Brazilian kind weighs 12 units and each marble of the Indian kind weighs 11 units. Of the 8 boxes there is one box in which all of the marbles are of the Indian kind, all others contain marbles of the Brazilian kind only. You are given a weighing scale (assume it’s digital). How will you find out which box has the marbles of the Indian kind with only one weighing?
I have just started studying discrete math and I am still getting the hang of combinatorics. Any contribution is very much appreciated!
