A can complete a piece of work in 24 days. He works alone for 6 days and then leaves; B completes the remaining work in 12 days. In how many days can B alone complete the whole work?

Question

Accepted Answer

16. A does 6/24 = 1/4 of the work, leaving 3/4 for B, done in 12 days; so B's full-work time = 12 ÷ (3/4) = 16 days.
