Question:

A can do a piece of work in 40 days. Along with B he finished the work in 24 days and together they got Rs. 1,000 for it. What was B's share?

Explanation:

A can complete the work alone in 40 days.

∴ Work done by A in 24 days = $\frac{24}{40}$ = $\frac{3}{5}$ ^t h

∴ Work done by B in 24 days = 1 - $\frac{3}{5}$ = $\frac{2}{5}$ ^th

⇒ Payment that B recieves will be 2/5^th of the total payment = $\frac{2}{5}$ × 1000 = Rs. 400

Hence, option (c).
