Question

Rajeev and Anuj can do a piece of work in 15 and 18 days respectively. They work together for 5 days and then Rajeev leaves. In how many days would Anuj alone finish the work?

Answer 1

Rajiv can do a piece of work in one day = 1 /15. Anuj can do a piece of work in one day= 1 / 18. They can work together in one day=1/15+1/18
=11/90
They can work together in 5 day=11/90×5
=11/18.
Remaining work=1-11/18=7/18.
Anuj can do alone in =7/18×18=7days.
