I was'nt sure of the way to do this..

here is my way..

w/C=5/2 ; C/M=5/11

if number of women is less than 30..

suppose w= 25..

25/10 = 10/22

so ratio of men to women 22/25 ?

I think its inconclusive because we dont know the exact number of any of the 3 groups.
Less than 30women could mean 25,20,15,10 or any other number.
Please correct me if I am wrong

cheers!!

C

W:C = 5:2

(1) tells that C:M = 5:11
Combine them:
25:10:22 = W:C:M
Number of men can be 22, 44, 66, etc. Can't find without total.
INSUFFICIENT

(2) Don't have men info
INSUFFICIENT

Together, we have
25:10:22 = W:C:M
Number of women can be 25, 50, 75, etc.
But since the number is less than 30, then it can only be 25.
This means number of men is 22
SUFFICIENT
