Say the number of workers = W = (Number of officers + Rest)
Hence, Rest = (W - 12)
Total salary = (Total number of worker)*(Avg salary per head of all workers) = 60W
Again, total salary = Total salary of the officers + Total salary of the rest = 12*400 + (W - 12)*56
So, 60W = 12*400 + 56(W - 12)
--> 60W = 4800 + 56W - 12*56
--> 4W = 4800 - 12*56
--> W = (4800 - 12*56)/4 = 1200 - 3*56 = 1200 - 168 = 1032
Therefore, the total number of workers in the factory is 1032.
