32. 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.30 Days B.27 Days
C.18.Days D.15 Days
Answer:
(A's 1 day's work) : (B's 1 day's work) = 2: 1.
(A + B)'s 1 day's work =1/18.
Divide 1/18 in the ratio 2 : 1.
:. A's 1 day's work = [1/18 X 2/3] = 1/27
Hence, A alone can finish the work in 27 days.
