A is twice as good a workman as B and together they finish a piece of work in 18 days. In how many days will A alone finish the work?
A. 45 days
B. 27 days
C. 36 days
D. 54 days
Answer: Option B
Solution (By JKSSB Mock Tests)
Ratio of work done by A and B = 2:1. Let B's 1-day work be x, so A's 1-day work is 2x. Together, 3x = 1/18, which means x = 1/54. A's 1-day work = 2 * (1/54) = 1/27. Thus, A alone completes it in 27 days.
