C Correct answer
Explanation

A and B invest in ratio 9:7, so their profit shares are in ratio 9:7. Total profit parts = 9 + 7 = 16. After 10% charity, 90% remains for distribution. B's share is 7/16 of 90% of total profit. B's share = (7/16) × 0.9 × Total = Rs. 1260. Therefore, Total = 1260 × 16/(7 × 0.9) = 1260 × 16/6.3 = Rs. 3200.
