Effort of 900M + 500W in 2 weeks  is equivalent to effort of 1200M + 250W in 3 weeks.

So (900M + 500W) X 2 = (1200M + 250W) X 3

36M = 5W

Therefore,W = (36M)/5

Required number of men = x to do the same task in 1 week.

So (900M + 500W) X 2 = (xM) X 1             [ substitute W = (36M)/5 ]

Solving, x = 9000.

So 9000 men are needed to do the same task in 1 week.
