Explanation
1. A can give B 15 points in 60It means when A makes 60 points, B makes only 60 - 15 = 45 points.
So, Ratio A : B = 60 : 45
2. A can give C 20 points in 60
It means when A makes 60 points, C makes only 60 - 20 = 40 points.
So, Ratio A : C = 60 : 40
3. Find B : C
Make A equal in both.
When A = 60, B = 45 and C = 40
So when B = 45, C = 40
When B = 90,
C = (40 / 45) x 90 = 80
So in a game of 90, when B makes 90, C makes only 80.
B can give C = 90 - 80 = 10 points in a game of 90.
