If A completes a work in 1 day, B completes the
same work in 3 days
Hence, if the difference is 2 days, B can complete
the work in 3 days
=> if the difference is 60 days, B can complete the
work in 90 days
=> Amount of work B can do in 1 day= 1/90
Amount of work A can do in 1 day = 3 × (1/90) =
1/30
Amount of work A and B can together do in 1 day
= 1/90 + 1/30 = 4/90 = 2/45
=> A and B together can do the work in 45/2 days
= 22 ½ days
