Answer:

a can do a work in 32 days

A one day work is 1/32

A 4 day work =1/32 ×4

=1/8

remaining work =1-1/8

=7/8

whole work complete in 24 days

A alone work for 4 days

(A+B) can do 7/8 work in 20days

(A+B) can whole work in=20×8/7

=160/7

B one day work is =(A+B) -A

=7/160 - 1/32

=(7 - 5)/160

=2/160

=1/80

B can complete whole work in 80 days
