Krishna and Callum are playing a game where they earn 10 points if they win any round. If they played eight matches and Krishna won 3/4 of the matches, what is the total number of points that Callum earned? Think carefully first, then make a decision:
Krishna won 3 / 4 * 8 rounds = 6 rounds. If they played eight rounds, Callum won 8 rounds - 6 rounds = 2 rounds. If a round earns one 10 points, Callum got 2 rounds * 10 points / round = 20 points. So, the answer is 20.
