Suppose, the dimension of wall built by one man per day equals to W, and everyone has the same workload. Then, the dimension of wall built by 18 men in 12 days can be calculated as, 18*12*W=216W. We assume the number of men employed to build a similar wall in 9 days is M. So, 9MW=216W, rearrange the equation, we get M=24.
