B Correct answer
Explanation

Investments: A = Rs. 36000, B = Rs. 42400, C = Rs. 28800. The profit is shared in the ratio of investments: 36000 : 42400 : 28800. Simplify by dividing by 400: 90 : 106 : 72. C's share is 72/(90+106+72) = 72/268 of total profit. If C gets Rs. 9900, then total profit = 9900 × 268/72 = Rs. 36850. Option B is correct.
