Hi All,
We're told that X is NOT equal to 0. We're asked if Y is greater than 0. This is a YES/NO question. This question can be solved by with a mix of Number Properties and TESTing VALUES.
1) (X)(Y) = 24
IF....
X = postive and Y = positive, then the answer to the question is YES.
X = negative and Y = negative, then the answer to the question is NO.
Fact 1 is INSUFFICIENT
2) X - Y = 5
IF....
X = 6 and Y = 1, then the answer to the question is YES.
X = -1 and Y = -6, then the answer to the question is NO.
Fact 2 is INSUFFICIENT
Combined, we know...
(X)(Y) = 24
X and Y are either BOTH positive OR BOTH negative.
X - Y = 5
IF...
X = 8 and Y = 3, then the answer to the question is YES
X = -3 and Y = -8, then the answer to the question is YES
Combined, INSUFFICIENT
Final Answer: E
