W:C =5:2

1) C:M = 5:11 = 1:11/5 = 2: 22/5

then we know W:C:M --> 5:2:22/5 = 25:10:22
not sufficient
we don't know the number of W or C or M or total

2) no of W<30
not suffcient

combined
W:C:M = 25:10:22
We can't have any fraction of W or C or M..

if W<30 ... 25 is the only number (whole numberm, not fraction)
Nof of W =25
No of M =22

Sufficient
