Is x - y > 0?
(1) x > |y|
(2) y = -3
The OA is the option A.
Why is the first statement sufficient? Could someone explain this to me? I'd really appreciate it.

Question stem, rephrased:M7MBA wrote:Is x - y > 0?
(1) x > |y|
(2) y = -3
Is x > y?
Statement 1:
Case 1: y=0, implying that x > |0| and thus x > 0
Case 2: y=1, implying that x > |1| and thus x > 1
Case 3: y=-1, implying that x > |-1| and thus x > 1
Case 4: y=10, implying that x > |10| and thus x > 10
Case 5: y=-10, implying that x > |-10| and thus x > 10
In every case, x > y.
Thus, the answer to the rephrased question stem is YES.
SUFFICIENT.
Statement 2:
No information about x.
INSUFFICIENT.
The correct answer is A.
