• A. Rs.$10$
• B. Rs.$20$
• C. Rs.$30$
• D. Rs.$40$

Answer 1

The correct option is B Rs.$20$

Let C=x. Then $A=\left(\begin{array}{c}x-20\end{array}\right)$ and $B=\left(\begin{array}{c}x-40\end{array}\right)$.
$x+x-20+x-40=120$ Or $x=60$
$A:B:C=40:20:60=2:1:3$
B"s share $=Rs.120\times \frac{1}{6}=Rs.20$
