Step-by-step explanation:
1/a =3/b
A+B can do the ⅓work in 3 day
In 1 day A+B can do 1/9 part of the work
ratio in which they work a:b = 3:1
total work done = 4parts =1/9
a share of work = 3 parts =3/4×1/9=1/12 in 1 day
A takes 12 days to finish the work
b share of work = 1 part = 1/4 ×1/9 =1/36 in 1 day
B takes 36 days to finish the work
