A is twice as good a work man as B and together they finish a piece of work in 36 days.The number of days taken by B alone to finish the work is : Pick
A) 100 days. B) 108 days. C) 98 days. D) 47 days. E) 103 days.
Solution   (A’s 1 day’s work): (B’s 1 day’s work)= 2 : 1.   (A + B)'s 1 day’s work = 1/36   Divide 1/36 in the ratio 2 : 1.   ∴ B’s 1 day’s work = (1/36 x1/3)= 1/108   Hence,B alone can finish the work in 108 days.   Answer 108 days.
