A is twice as good a workman as B and together they finish a piece
in 18 days. In how many days will A alone finish the work?	Choose the most appropriate option:	A) 27 days	B) 32 days	C) 54 days	D) 16 days	E) 29 days
Sol. (A’s 1 day’s work):)(B’s 1 days 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*2/3)=1/27   Hence, A alone can finish the work in 27 days.   Option: 27 days
