1 : Sufficient
Ratio in division Y is less than that of company Z. there are only two divisions and so it must be more for the other division.

2: Sufficent
Division X has
more than half of full time employees & less than half of part time [Y has more than half] employees

X - FT 50; x-PT 100/ 10
Y - FT 20; y-PT 200/ 200

1. The ratio of nymber of full time employees to the number of part-time employees is less for Division Y that for company Z - This states that the number of FT employess is more than the number of PT employes in dept Y. Can't make out the number for X with this.
Insufficient

2. More than half of the full time employees of company Z are employees of Division X, and more than half of the part-time employees of Company Z are employees of Division Y. - Thus the ratio of X/x > 1 if 50/10 but X/x < 1 if 50/100
Thus insufficient
