Anil, Kamal and Vini invested Rs. 8000, Rs. 4000 and Rs. 8000 respectively in a business. Anil left after 6 months. If after 8 months, there was a gain of Rs. 4005, then what will be the share of Kamal ?

Answer: Option B

Ratio of profit of Anil : Kamal : Vini
(8000 × 6) : (4000 × 8) : (8000 × 8)
= 48000 : 32000 : 64000
= 48 : 32 : 64
= 3 : 2 : 4
$$\begin{array}{rl}& \therefore \text{Kamal’s share}\\ & =\text{Rs}\text{.}\left(4005\times \frac{2}{9}\right)\\ & =\text{Rs}\text{.}\text{890}\end{array}$$
