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?ÂSolution
Let’s assume the total work = 1 unit (or 1 whole work).
So, Jason’s 1 day work = 1/20
Jason + Jamal’s 1 day work together = 1/9
Jamal’s 1 day work = (Jason + Jamal)'s 1 day work − Jason’s 1 day work = 1/9 - 1/20 = 11/180
Jamal alone can complete the work in 180/ 11 days, or approximately 16.36 days
