GMAT Prep Q

On a sight-seeing tour, the ratio of the number of women to the number of children was 5 to 2. What was the number of children was 5 to 2. What was the number of men on the sight-seeing tour?
(1) On the sight-seeing tour, the ratio of the number of childrn to the number of men was 5 to 11.
(2) The number of women on the sight-seeing tour was less than 30.


Ans is C

My Soln]
Considering 1 and 2
we have w:c = 5:2 and c:m = 5:11 => w:c:m = 25*17:10*7:22*7
From this we can get an inequality but how can you find the exact number of men?

Hi,
w:c = 5:2
From(1): c:m = 5:11
So, w:c:m = 25:10:22
Not sufficient
From(2): w<30
Not sufficient
Both(1)&(2): w:m = 25:22
and w<30 As w and m should be integers, only possible set of values is 25, 22
So, m =22
Sufficient

Hence, C
Cheers!
