Answer 1

Answer:

A and B undertake to do a piece of work for Rs. 450. A can do it in 20 days and B can do it in 40 days. With the help of C, they finish it in 8 days. How much should C be paid for his contribution?

A = 20 days

B = 40 days

A+B+C = 8 days

Total Work = 40 unit

One day work

A = 2u

B = 1u

A+B+C = 5u

C = 5 - 3 = 2u

A:B:C = 2u:1u:2u = 5u

5u = Rs 450

1u = Rs 90

2u = Rs 180 Ans
