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

Answer (as printed): B

Explanation

$A: B=100: 80$ and $A: C=100: 72$. $$\therefore \frac{B}{C}=\left(\frac{B}{A} \times \frac{A}{C}\right)=\left(\frac{80}{100} \times \frac{100}{72}\right)=\frac{10}{9} \times \frac{10}{10}=\frac{100}{90}=100: 90 .$$ $\therefore B$ can give $C 10$ points.
