Question

9. 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?
In uhat time can h men and 11 women do it?​

Answer 1

So it would take A double time to do the work so it should take 50 days to do the work instead of 25 days

Answer 2

Assume total work 25 units

A& B worked 15 days

i.e 15 units completed.

remaining work 10 units done by A in 20 days

i.e 10/20 = 1/2 is A's efficiency.

A can do 1/2 unit in one day.

A needs 50 days to complete whole 25 units work.
