Solution(By Apex Team)

Ratio of investments of A, B and C = Ratio of their profits $\begin{array}{l} =337.50: 1125: 637.50 \\ =9: 30: 17 \end{array}$ ∴ A’s investment $\begin{aligned}&=\text{ Rs. }\left(14000\times\frac{9}{56}\right)\\ &=\text{ Rs. }2250\end{aligned}$ B’s investment $\begin{aligned}&=\text{ Rs. }\left(14000\times\frac{30}{56}\right)\\ &=\text{ Rs. }7500\end{aligned}$ Hence, Required difference $\begin{array}{l} =\text { Rs. }(7500-2250) \\ =\text { Rs. } 5250 \end{array}$
