Question

A and B can do a job together in 25 days. After 15 days of working together, B leaves. If A
completes the remaining part of the job in 20 days, how long would each take to complete
the job, working separately?
6 men and 11 women do it?​

Answer 1

Step-by-step explanation:

A and B one day work=1/25

A and B 15 day work =15/25=3/5

work remain =1-3/5=2/5

A complete the work in 20 days

A one day work =2/5*20=1/50

A complete work in 50 days

B one day work=1/25-1/50=1/50

B complete work in 50 days
