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
