Let total work be 60
Capacity of p = 1 work/day
Remaining work =60-15
=45 work

Time taken by q to do remaining work = 30

Capacity of q = 45/30= 3/2

Capacity of both = 1+3/2 =5/2
Time taken by both = 60/5/2=24 days

Answer 2

Thanks for asking this question.

Now, A can do a piece of work in 60 days. So, let the TOTAL WORK = 60 units.

A -> 60 days = 1 unit/day
So, in 15 days, A has completed 15 units.

Remaining Work = 45 units. Time taken by q to do remaining work = 30 Capacity of q = 45/30= 3/2 Capacity of both = 1+3/2 =5/2 Time taken by both = 60/5/2=24 days
