Question

A can do a peace of work in 25 days and B can finish it in 20 days. they work together for 5 days and then A leaves. in how many days will B finish the remaining work​

Answer 1

Step-by-step explanation:

According to the information given from the questions we can say :-

In 1 day A can complete 1/25 of the work

In 1 day B can complete 1/20 of the work

Together they can complete :- 1/25+ 1/20 work in one day

Hence in 5 days they can complete :- 5/25 + 5/20 work.

OR

9/20 work.

Remaining work :- 1–9/20 work = 11/20 work

Hence B can complete the remaining 11/20 work in 11/20 / 1/20 = 11 days.
