**drwls**, Saturday, August 11, 2012 at 3:38amPresumably 6 builders working 8 hour days accomplish the same work as 8 builders working 6 hour days. After three days of work by 8 builders working 6 hour days, there will still be seven days of work needed, at 48 manhours per day. That is a total of 336 manhours. To complete the remaining work in eight days, you need to perform 42 manhours per day. With six workers, they would have to work 7 hours per day.
