I have never seen a question like this before. How are you suppose to know how many points each person has at the beginning?

If we have to calculate for b/c then we should do b/a * a/c to cancel a.

From b:c we know 80-72 = 8.
i.e from 80 points b can give c 8 points.
In time and work problems we assume work is always one (1).
In the same way we have to calculate for 100 points in races topic because getting 100 points is the game winner.
For 80 b can give c 8 points.
For 100 b can give c 10 points.
