M x T / W = Constant where, M= Men (no. of men) T= Time taken W= Work load So, here we apply M1 x T1/ W1 = M2 x T2 / W2 Given that, M1 = 4 men, T1 = 7 hours ; T2 = 2 hours, we have to find M2 =? Note that here, W1 = W2 = 1 road, ie. equal work load. Clearly, substituting in the above equation we get, M2 = 14 men.
