Answer:
{121,144,169} X intersecting Y means common number between x and y set
<h2>B is the correct answer</h2><h3><em>Let me know if I am wrong.</em></h3>
No. which have factors 2 & 5 have 2 & 5 as their prime factor
therefore, No. are :
2*5 = 10
2*5*2 = 20
2*5*3 = 30
There would be 80 women.
Here's the work:
120 divided by 3 = 40
If the ratio is 3:2, there is always one less woman then men, so you subtract the 40 men in a group and you get your answer of 80
