In a game of 250 points A can give B 50 points and C 70 points. In the same game how many points can B give C?

In a game of 250 points, A scores 250 then B scores 200 points and C scores 180.
∴ B scores 250 points while C scores 180 x 250 / 200 = 225 points
Hence, in a game of 250 points B can give C (250 – 225) = 25 points
