Correct Answer: 10. (3)
Solution: 10. (3) Let initial amount be Rs. $x$.
$\therefore \mathrm{A} \Rightarrow \frac{x}{2}+40$
$\mathrm{B} \Rightarrow \frac{3 x}{8}-120$
$\therefore$ C’s share
$=x-\frac{x}{2}-40-\frac{3 x}{8}+120$
$=x-\frac{x}{2}-\frac{3 x}{8}+80$
$=\frac{8 x-4 x-3 x}{8}+80$
$=\frac{x}{8}+80$
According to the question,
$\frac{x}{8}+80=200$
$\Rightarrow \frac{x}{8}=200-80=120$
$\Rightarrow x=120 \times 8=$ Rs. 960
