Question

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?

Answer 1

Hey Dear,

◆ Answer -

Payment to C = 180 Rs

● Explanation -

A can do 1/20th work in day, hence work done by him in 8 days -

A = 1/20 × 8 = 2/5th work

B can do 1/40th work in day, hence work done by him in 8 days -

B = 1/40 × 8 = 1/5th work

Now part of work done by C in given project is -

C = 1 - 2/5 - 1/5 = 2/5th work

So C should be paid 2/5th of earned amount.

Payment to C = 2/5 × 450

Payment to C = 180 Rs

Therefore, C should be paid 180 Rs for his contribution.

Thanks dear...
