Given $$m:c=4:3$$ we need number of women?

Statement 1: number of women can be any number less than $$40$$. Insufficient

Statement 2: we have $$c:w=4:11$$ and $$m:c=4:3$$ , $$c$$ is common in both the ratios, hence to combine the ratios we need a common value of $$c$$ in both the ratios

$$=> m:c:w=16:12:33$$. but we have no value here. Insufficient

Combining 1 & 2: we know number of women is a multiple of $$33$$ and less then $$40$$. so number of $$women=33$$. Sufficient

Option C

M:C =4:3 & C:W=4:11 . Thus M:C:W=16:12:33. Let k be constant.

So, Men = 16K
Children = 12K
Women = 33K

Bunuel : Can you explain, why C is correct.

Without knowing total population, how can we consider number of women as 33 ?

Considering value of K =1/3 , women population also can be 11 which is less than 40.

So (1) + (2) may not be correct. Please let me know, where am I getting wrong.

K=1/3
Men = 16K=5.33 ??
Children = 12K=4
Women = 33K=11
