In a game of 50, A can give B 5 points, and in a game of 60, B can give C 12 points. How many points can A give C in a game of 50?

Explanation

1. 01

   When A scores 50, B scores 45. C scores $\frac{48}{60} = \frac{4}{5}$ of B's points.

2. 02

   So when A scores 50, C scores $45 \times \frac{4}{5} = 36$: A gives C 14 points.
