Question

6. A can do a piece 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?

Direct and inverse variation. ​

Answer 1

hey mate here is ur answer

In 1 day A can complete 1/25 of work

In 1 day B can complete 1/20 of work

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

hence,

in 5 days they can complete 5/25 + 5/20= 9/20

Remaining work is 1 - 9/20 work = 11/20 work

hence B can complete the remaining 11/20 in

hope it helps u dear....
