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

1) The ratio of the number of full-time employees to the number of part-time employees is less for Division Y than for Company Z

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.

I'm not quite sure how to do this problem.... any help would be appreciated.
Thanks.

I would say D, either statement is sufficient, but it took me awhile to prove it. I drew ratio diagrams for each statement and plugged in numbers. If I got this problem on the test, I think I would have guessed D without trying to solve it - way too much time for me. Both statements logically seem to give enough information.
