In a game of 100 points, A can give B 20 points and C 28 points. Number of points B can give C in a game of 100 points is:
Correct Answer: 10
Explanation:
A scores 100 while B scores 100 - 20 = 80 and C scores 100 - 28 = 72.
∴ While B scores 80, C scores 72.
∴ While B scores 100, C scores 72 × 100 / 80 = 90.
∴ B can give C 100 - 90 = 10 points.
