Answer:
B
Explanation:
A is twice as good a workman as B, so the ratio of A's work to B's work is 2 : 1. A and B can finish the work in 18 days, so the amount of work they complete in 1 day is (1/18) of the total work. We can divide the amount of work they complete in 1 day in the ratio 2 : 1, with A completing 2/3 and B completing 1/3. Therefore, A's 1 day's work is (1/18) * (2/3) = 1/27 of the total work. Since A completes (1/27) of the total work in 1 day, it will take him 27 days to complete the entire work.
