Answer:
Option A
Explanation:
Ratio of shares of $A$, $B$ and $C$ = Ratio of their investments
$=120000:135000:150000$ $=8:9:10$.
A's share = Rs. $\left(56700\times\frac{8}{27}\right)$ = Rs. 16800.
B's share = Rs. $\left( 56700\times\frac{9}{27}\right)$ = Rs. 18900.
C's share = Rs. $\left(56700\times\frac{10}{27}\right)$ = Rs. 21000.
