A, B and C started a business together. The ratio of the investment of A to that of B was 5 : 6 and the ratio of the investment of B to that of C was 12 : 14. If at the end of the year, C received Rs. 2,2,75 as his share of annual profit, what was the total annual profit earned by all of them together?
Ratio of investment of A to B = 5:6 Ratio of investment of B to C = 12 : 14 = 6:7 Ratio of investment of A to B to C = 5 : 6 : 7 C’s share = 7/(7+6+5)×total profit =2275 ∴ Total profit = 2275 × 18/7 = Rs. 5,850
