Answer:
6 days
as both work together assume work done by A is x/12 and by B=x/6
Answer:
A = 6 days = 1 job , 1 day = 1/6
B = 12 days = 1 job , 1 day = 1/12
2/12 + 1/12 = 3/ 12
12 / 3 = 4 days together
Both A and B can do the work combined in= 6 x 12/ (6+12)
= 72/18 =4- days

A can do a piece of work in 6 days. So A can do
A can do a piece of work in 6 days. So A can do1/6 part of the work in 1 day. And B can do the same in 12 days, so B can do 1/12 part in a day. The total part both together do is....
A can do a piece of work in 6 days. So A can do1/6 part of the work in 1 day. And B can do the same in 12 days, so B can do 1/12 part in a day. The total part both together do is....1/6 + 1/12 = (2+1)/12 or 3/12 = 1/4 part of the whole work.
A can do a piece of work in 6 days. So A can do1/6 part of the work in 1 day. And B can do the same in 12 days, so B can do 1/12 part in a day. The total part both together do is....1/6 + 1/12 = (2+1)/12 or 3/12 = 1/4 part of the whole work.Therefore both A and B can do the whole work in..... 1 divided by (1/4) = 4 days. Answer.
