Answer:

30 days

Step-by-step explanation:

A and B can do the work in 12 days

work in one day= 1/12 part

A can do the work in 20 days

work in one day=1/20 part

So,

B's one day work=

=A and B's 1 day work- A's one day work

=1/12-1/20

=(5-3)/60

=1/30

Time taken by B to complete the work=1/(1/30)days

=30 days
