This is from a video by Aditya Kumar from Crackverbal on gmatclub YouTube channel.
Is x|y|>y² ?
1. X>0
2. X>Y
When I tried to analyse the question, I came up with three conditions I'd need for the equation to be true-
y not equal to 0
x is positive, &
x>y
But Aditya in the video said "we will ignore y=0 as a possibility". I don't understand why we would do that since that is a valid option. Imo, if y=0 is not given, then that's a possibility and makes the answer 'No'.
Can someone please explain?

Hello there,
You can find a detailed discussion of this question at this link. If you have any further questions, please feel free to ask in the discussion thread. I hope you find the information helpful.

Please note that this topic has been locked and archived.
P.S. Worth noting though that such type of pure algebraic questions are no longer a part of the DS syllabus of the GMAT.
DS questions in GMAT Focus encompass various types of word problems, such as:
- Word Problems
- Work Problems
- Distance Problems
- Mixture Problems
- Percent and Interest Problems
- Overlapping Sets Problems
- Statistics Problems
- Combination and Probability Problems
While these questions may involve or necessitate knowledge of algebra, arithmetic, inequalities, etc., they will always be presented in the form of word problems. You won't encounter pure "algebra" questions like, "Is x > y?" or "A positive integer n has two prime factors..."

Hope it helps.
