Question 8

A can do a piece of work in 12 days while B alone can do it in 15 days. With the help of C they can finish it in 5 days. If they are paid Rs. 960 for the whole work how much money A gets ?

Solution

let c can complete the work in x days.

1/12 + 1/15 + 1/x = 1/5

1/x = 2/15 - 1/12

x = 20.

thier efficiencies are 1/12, 1/15, 1/20

i.e; 5, 4, 3

If they are paid Rs. 960

the money get by A is 5/(5+4+3) *960

= (5/12) *960

= 400.

so the answer is option D.
