The rate at which Masons build walls is what we need to understand with this problem. 15*X = 20 15*X/20 = 1 Wall Therefore, a fifteenth of a wall can be built by one mason in 20 days. Each day, a mason can build 1/(15*20) or 1/300th of an entire wall. Therefore, it would take one mason 300 days to build a wall on their own. It would take 15 masons 20 days (300/20) to build a wall. And we can estimate the 12 day solution with the following formula: 300/12 = 25 It would take 25 masons 12 days .
