Question
Jason alone can complete a piece of work in 20 days. In
how many days can Jamal alone do the same work, if both of them together can do the same work in 9 days?ĀSolution
Letās assume the total work = 1 unit (or 1 whole work).
So, Jasonās 1 day work =Ā 1/20
Jason + Jamalās 1 day work together = 1/9
Jamalās 1 day work = (Jason + Jamal)'s 1 day work ā Jasonās 1 day work = 1/9 - 1/20 = 11/180
Jamal alone can complete the work inĀ 180/ 11 days, or approximately 16.36 days
