Answer 2

Step-by-step explanation:

A and B complete 1/12 and 1/18 of work respectively in 1 day.

They complete (1/12 + 1/18) or 5/36 of work together in 1 day.

Working together for 2 days, they complete 2 × 5/36 or 5/18 of work.

After A leaves, B is left with 1-5/18 or 13/18 of work.

As B completes 1 work in 18 days, he'll take 13/18 × 18 or 13 days to complete remaining 13/18 work.

Ans: 13.
