Step-by-step explanation:
A+B can do work in 20 days
A+B one day =1/20 part of the work
B can do a work in 30 days
B in one day does 1/30 part of work
A part of work in a day
= A+B -B
= 1/20 - 1/30= (30-20)/(20× 30)
=10/(20×30) = 1/60
A can do 1/60 part of the work in one day
A can do whole work in 60 days
