Correct Answer - Option 1 : Rs. 750
Given:
⇒ Total investment of P = 500 × 5 + 750 × 7 = Rs.7750
⇒ Initial investment of Q = 500 × 40/100 = Rs.200
⇒ Total investment of Q = 200 × 4 + 400 × 8 = Rs.4000
Ratio oft their profit shares = 7750 : 4000 = 31 : 16
∴ Required difference = 2350 × (31 - 16) /(31 + 16) = Rs.750
