a) Rs. 2200
b) Rs. 3200
c) Rs. 4200
d) Rs. 5250
Answer: d
Explanation: Ratio of investments of A, B and C = Ratio of their profits
$$\eqalign{
& = 337.50:1125:637.50 \cr
& = 9:30:17 \cr
& {\text{A’s investment}} = {\text{Rs}}{\text{.}}\left( {14000 \times \frac{9}{{56}}} \right) \cr
& = {\text{Rs. }}{\text{2250}} \cr
& {\text{B’s investment}} = {\text{Rs}}{\text{.}}\left( {14000 \times \frac{{30}}{{56}}} \right) \cr
& = {\text{Rs. }}{\text{7500}} \cr
& {\text{Required difference}} = {\text{Rs}}{\text{.}}\left( {7500 – 2250} \right) \cr
& = {\text{Rs. }}{\text{5250}} \cr} $$
