A can do a piece of work in 10 days, while B can do it in 6 days. B worked at it for 4 days. How long will A take to finish the remaining work?

Question

Accepted Answer

B's 4 days work = (1/6) x 4 = 2/3 ∴ Remaining work = 1 - (2/3) = 1/3 A's 1 day's work = 1/10 ∴ 1/3 work is finished by A in (10 x 1/3) = 31/3 days
