A csn do a piece of work in 40 days

Work of A in 1 day=1/40

Work of A in 5 days=5/40=1/8

1/8th part of work is done by A

Remaining work=(1−81)=87

7/8th part is done by B in 21 days

Total work will be done by B  in =8721=721×8=24days

Work done by B in one day=1/24

Work done by A and B together in one day will be(401+241)

 (1203+5)=1208=151

A and B will take 15 days to complete the work together.
