As per question, A do twice the work as done by B.
So A:B = 2:1
Also (A+B) one day work = 1/12
To get days in which B will finish the work, lets calculate work done by B in 1 day =
=1/12 X 1/3 = 1/36
(1*12 X 1*3= 36)
[Please note we multiplied by 1/3 as per B share and total of ratio is 1/3]
So B will finish the work in 36hours
hope this help........:)
if help then plz mark as brainliest....:)
