Answer: 6 days
Step-by-step explanation:
A and B together can complete a work in 3 days. This means that A and B together can complete 1/3rd of the work in one day. So in two days they completed 2/3 rd of the work and 1/3 rd remains.
This 1/3rd work A Completes in 2 days
So in one day A alone can complete 1/6th of the work
So in one day B alone can complete 1/3 - 1/6 = 1/6 th of the work
So B alone can complete the work in 6 days
