If the original price of an item in a retail store is marked up by m percent and the resulting price is then discounted by d percent, where m and d are integers between 0 and 100, is the item’s final price (after both changes) greater than its original price?
(1) m > d
(2) m = 1.5d
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
Both statements TOGETHER are sufficient, but NEITHER one ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.

Re: If the original price
if you have specific questions about this problem -- i.e., if you understand MOST of what's happening in the problem, but there are one or two "sticking points" -- THEN please post those questions here.
i.e., you should be able to articulate
• what approach(es) you've tried so far,
• what you ALREADY UNDERSTAND about the problem,
• what, SPECIFICALLY, you don't understand,
• where you're getting stuck.
if you really, genuinely have no idea how to do a problem, then you won't derive any value from an explanation of it -- even from a very, very good explanation.
worse yet, you'll be wasting the problem, since it will no longer be "fresh" for a time when you ARE capable of tackling it.
__
you should classify problems as "green light", "yellow light", or "red light".
GREEN LIGHT: you're totally ok with the problem, and can solve it without significant trouble.
YELLOW LIGHT: there are one or two sticking points, but you understand MOST of what's happening in the problem.
RED LIGHT: the problem mostly or entirely confuses you.
the point is that you should NOT waste your time studying "red light" problems, EVER. you should save those until they are no longer "red light".
the forum should be for your "yellow light" problems.
