Question:
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?
A ) 25 days
B ) 26 days
C ) 28 days
D ) 27 days
Answer : D) 27 days
Explaination :
(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 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.
