A can complete a job alone in 15 days and B alone in 20 days. A, B, and C together complete the job in 6 days. They agree to share ₹9,000 for the work. How much should C be paid?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. ₹2,700.
Combined work rate of A and B = 1/15 + 1/20 = 7/60
Work rate of A, B, and C together = 1/6
C’s work rate = (1/6) - (7/60) = 1/20
A : B : C = 1/15 : 1/20 : 1/20 = 4 : 3 : 3
C’s share = 3/10 × 9000 = 2700
