A can complete a task in 6 days and B in 8 days when working alone. A and B agreed to do it for 3200 rupees. They finished the job in three days with the aid of C. What is the amount to be paid to C?
A. Rs. 375 B. Rs. 400 C. Rs. 600 D. Rs. 800
Explanation: 1 day's labour for C = 1/3 - 1/6 + 1/8 = 1/3 - 7/24 = 1/24.1/6 : 1/8 : 1/24 = 4 : 3 : 1 = A's wages : B's wages : C's wages.3 × 1/24 x 3200 = Rs. 400 for C's share (for 3 days).
