On Friday I posted this puzzle….
A carpenter is paid 2 pounds for each day that he works and forfeits 3 pounds for each day that he doesn’t work. After 30 days he has paid out exactly as much as he has received. How many days did he work?
If you have not tried to solve it, have a go now. For everyone else the answer is after the break.
The carpenter worked on 18 days and didn’t work on 12 days
