Correct answer
Explanation
A invests 2800 for 6 months = 2800 × 6 = 16800. B invests 2100 for 12 months = 2100 × 12 = 25200. C joins with 25% of A's capital = 700 for 8 months (from when A leaves to year-end) = 700 × 8 = 5600. Total = 47600. B's share = (25200/47600) × 930 ≈ 493.67. Nearest option is Rs. 540, though exact calculation shows discrepancy.
