Verified Solution

Answer & Solution

Correct Answer

(A) 10 points

Step-by-step Solution

Detailed explanation

\(A:B = 60:(60-15) = 60:45 = 4:3\) \(A:C = 60:(60-20) = 60:40 = 3:2\) \(B = \frac{3}{4}A\) \(C = \frac{2}{3}A\) \(C = \frac{2}{3} \left(\frac{4}{3}B\right) = \frac{8}{9}B\) When B scores 90, C scores \(C = \frac{8}{9} \times 90 = 80\) Points B can give C = \(90 - 80 = 10\)
