A contractor had employed 100 labourers for a flyover construction task. He did not allow any woman..

Answer / guest

16 men, 12 women and 72 children were working with the
constructor.

Let's assume that there were X men, Y women and Z children
working with the constructor. Hence,

X + Y + Z = 100

5X + 4Y + Z = 200

Eliminating X and Y in turn from these equations, we get

X = 3Z - 200

Y = 300 - 4Z

As if woman works, her husband also works and atleast half
the men working came with their wives; the value of Y lies
between X and X/2. Substituting these limiting values in
equations, we get

if Y = X,

300 - 4Z = 3Z - 200

7Z = 500

Z = 500/7 i.e. 71.428

if Y = X/2,

300 - 4Z = (3Z - 200)/2

600 - 8Z = 3Z - 200

11Z = 800

Z = 800/11 i.e. 72.727

But Z must be an integer, hence Z=72. Also, X=16 and Y=12

There were 16 men, 12 women and 72 children working with the
constructor.
