Answer : Option B
Explanation :
If A scores 60 points, B scores 48 points.
Also, if A scores 90 points, C scores 80 points.
A: B = 60:48 and A: C = 90:80
B: C = (A/C) * (B/A)
= (90/80) * (48 /60) = 9/10
When C scores 10 points B scores 9 points.
So, When C scores 70 points B scores = (9/10) * 70 = 63 points
