A and B can do a piece of work in 10 days and 12 days, respectively. With the help of C, they completed the work in 5 days and earned Rs. 2460. What was the share of C?

205

C's Efficiency = 12 - (6 + 5)) = 1

                        A    :     B     :     C

Work Ratio →  6     :     5     :     1    

Total work done by C in 5 days = 5 × 1 = 5

Total share of C = \(\frac{2460}{60}\) × 5 = 205
