B is better than C in this scnario becuase we know B only needs one point in every 6 and C needs one in every 4

ratio of 1/6 : 1/4 but the questions asks when B and C play how many points will need to be spotted. In looking at the given points from A, B and C are nearly equals but B is slightly better than C. Actually 1/10 better.

In a game of 90, B will give C one point out of 10 so he will spot him 9.

Given that if A get 60 points, B get 50 points and C gets 45 points.

So in a game of 50 points, B can give C 5 points.
Hence in a game of 90 points, B can give C 9 points

How do you go from " A can give B 10 points in 60" to " if A get 60 points, B get 50 points "?

A can give B 10 points in 60: If A gets 60, then B gets 10/60

Hes showing the ratio of what it takes to be a fair game. To be fair, A has to score 60 point B only has to score 50 and C has to only score 45 to be fair.
