Each employee of company Z is employed in either Division X or Division Y, but not both. If each division has some part time employees, is the ratio of the number of full-time employees to number of part-time employees greater for Division X than for Company Z?

1) Ratio of number of full time employees to part-time employees is less
for division Y than for company Z

2) More than ½ of full-time employees of company Z are employees of
div X, and more than ½ of part-time employees of company Z are
employees of div Y


Statement B alone is suff but statement A alone is not.

From A: P1=part time employees of X
P2=Part time employees of Y
F1=Full time employees of X
F2=Full time employees of Y

Thus from A:

F2/P2< (F1+F2)/(P1+P2)

This can not be used to find a relation between F1,F2 and P1,P2
Am I missing something?

IMO D
