1 day both work = 1/8

1 day b work = 1/8-1/12 = 1/24

b alone can do in 24 days

please mark as brainliest

Answer 2

Here goes your answer :-

As A alone can finish work in 12 days so, A do 1/12 th portion of the work in one day.

Assume B alone completes x portion of work in one day.

As A and B together can finish a work in 8 days,

8((1/12)+(x))=1

so, x=1/24

So, B alone takes 24 days to do same work.
