Three persons stared a placement business with a capital of Rs. 3000. B invests Rs. 600 less than A and C invests Rs. 300 less than B. What is B's share in a profit of Rs. 886 ?

Answer: Option C

Let A's capital = Rs. x
Then, B's capital = Rs. (x - 600)
C's capital = Rs. (x - 600) - 300 = Rs. (x - 900)
∴ x + (x - 600) + (x - 900) = 3000
⇒ 3x = 4500
⇒ x = 1500
$$\begin{array}{rl}& \text{So, A}:\text{B}:\text{C}\\ & =1500:900:600\\ & =5:3:2\\ & \text{Hence, B’s share}\\ & =\text{Rs}\text{.}\left(886\times \frac{3}{10}\right)\\ & =\text{Rs}\text{. 265}\text{.80}\end{array}$$
