A does half as much work as B in three-fourth of the time. If the together they take 18 days to complete a work. How much time shall B take to do it?

Question

Accepted Answer

Let B takes N days to do the work ∴ A takes 2 x (3/4) x N = 3N/2 days to do it ∵ (A + B)'s 1 day's work = 1/18 ⇒ 1/N + 2/3N = 1/18 ∴ N = 30
