W:C = 5:2

1) C:M=5:11

W:C = 25:10
C:M= 5:11= 10:22
W:C:M= 25:10:22

With the above ratio multiple solutions possible.
M=22 or 44 or 66...
insufficinet
2) No of men <30
we know W:C= 5:2
Men can be any number 1,2,3,..
multiple solutions insufficient

combine both

W:C:M= 25:10:22
We can't have fraction of any Person(Woman /man/ children).

So "25:10:22 " ratio least integers without any fractions.

women<30.. means W=25 and M=22 and . other solutions are not possible..
say M=11 then W=12.5 thats not possible.


So . C is the answer.
