Answer:
2.5 more days
Step-by-step explanation:
A can do a work in 6 days. So, he can complete 100/6 = 16.66% of work in one day. Then, if he work for 2 days, he will complete 33.32% of the work.
B can complete a work in 8 days. So, he can complete 100/8 = 12.5% of work in one day. Then, if he work for 2 days, he will complete 25% of the work.
If A and B worked together for two days, 33.32+25 = 58.32% of the work must be completed. Hence, remaining 41.68% of the work must be done by A alone.
He would take 1 day to complete 16.66% of work and hence would take 41.68/16.66 = 2.5 more days to complete the remaining work.
