Question

In a game of 100 points, A can give B 20 points and C 28 points. Then, B can give C :

• A. 8 points
• B. 10 points
• C. 14 points
• D. 40 points

Answer 1

The correct option is B 10 points

$A:B:C=100:80:72$

Therefore,

$B:C=80:72$

$\frac{B}{C}=\frac{80}{72}=\frac{10}{9}=\frac{100}{90}$

If B scores 100, then C scores 90.

Hence, B can give C 10 points.
