A) 18 days
B) 36 days
C) 54 days
D) 60 days
Correct Answer: B
Solution :
In a day, A and B together can do 1 /12th of the work. In a day, A alone can do I/18th of the work \[\therefore \] In one day, work done by B alone is \[=\frac{1}{12}\,-\frac{1}{18}\,=\frac{1}{36}\] \[\therefore \] B alone can complete the work in 36 days.You need to login to perform this action.
