Question

A and B together can do a work in 12 days. A alone can do the work in 18 days. In how many days

can B alone complete the work.​

Answer 1

Answer:

(A+B) can work finished =12days

(A+B)can work finished in1days=1/12

A can work finished =18days

A can work finished in1days=1/18

B can work in 1days=1/12-1/18

3-2/36

1/36

B can work finished=36days

Answer 2

Answer:

(A+B)'s one day work = 1/12

A's one day work= 1/18

A+B =1/12

1/18 + B = 1/12

B = 1/12 - 1/18

B= 3-2/36

B = 1/36

Hence, B can complete it in 36 days.
