You can work this with ratios

#MdivC=4div1#
#WdivC=2div1#

Conclusion: #MdivWdivC=4div2div1#

The sum of the ratios is #4+2+1=7# which means we can divide the total number into #266div7=38# groups, each group having 1 child, 2 women and 4 men.

There will be
#38xx1=38# children
#38xx2=76# women
#38xx4=152# men

Note:
Another way would be to consider that #M=4C#, #W=2C#
#M+W+C=4C+2C+C=7C=266#
