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?

40 days
35 days
30 days
None of these

Correct Answer: 30 days

Explanation:

Let B takes N days to do the work
∴ A takes 2 x (3/4) x N = 3N/2 days to do it

⇒ 1/N + 2/3N = 1/18
∴ N = 30
