given w/c = 5/2

statement 1 :
c/m = 5/11
this gives the ration but not actual number
alone not sufficient

statement 2 :
w<30
alone not sufficient

taking both:

w/c = 5/2
c/m = 5/11

so
w/m = 25/22

given w<30

so w=25 hence m=22

both together sufficient
Stay focused

a+b

number of children will be multiple of 5 and 2. hence c=10 gives
w=25 and m=22.
C is true.
