A, B and C together can complete a work in 10 days. A and B together can do the same work in 12 days. If A, B and C received ₹9,000 for doing the work together, then what was the share of C from the above amount?
Answer & explanation
Correct answer: option 3
A + B + C = 10 days,
A + B = 12 days,
⇒ A + B + C = 6 (Efficiency)
⇒ 5 + C = 6,
⇒ C = 1,
Total wages for working together = Rs. 9000,
⇒ (5 + 1)x = 9000
⇒ 6x = 9000
⇒ x = Rs. 1500,
⇒ Therefore, C's share = 1 x 1500 = Rs. 1500.
