Answer:

In 6 days B can complete the work.

____________________

Let B can complete the piece of work in Y days .

In 1 day B can complete 1/Y part of the work.

A complete the whole work in 12 days.

In 1 day A can complete 1/12 part of the work.

Together A and B complete the work in 4 days.

In 1 day together they complete 1/4 part of the work.

According to the problem,

together's 1 day work = 1/4

or, 1/Y +1/12=1/4

or, 1/Y= 1/4 - 1/12

or, 1/Y = 2/12

or, 1/Y = 1/6

or, Y=6

Therefore, B can complete the whole work in 6 days
