Answer: 36 days

Explanation:-
A & B can complete a work = 24 days
Therefore,  A & B can a work in a day = 1/24

A & B can work in 20 days = 1 x 20/24
= 5/6
Remaining work = 1 – 5/6
= (6 – 5)/6
= 1/6
B can complete remaining work in 6 days = 1/6
Therefore, B can work in a day = 1/6 x 6
= 1/36

Then, B can complete the same work = 36 days

Hence, the answer is 36 days.
