Answer
Answer (as printed):
Explanation
$A: B=80: 75$ and $A: C=80: 65$. $\frac{B}{C}=\left(\frac{B}{A} \times \frac{A}{C}\right)=\left(\frac{75}{80} \times \frac{80}{65}\right)=\frac{15}{13}=\left(\frac{15 \times 4}{13 \times 4}\right)=\frac{60}{52} \Rightarrow B: C=60: 52$. Hence, in a game of 60, B can give C 8 points.
