Is x/y greater than 1 ?
(1) x > 3
(2) y > 3
Answer:
E
Source: GMAT prep
Target question: Is x/y greater than 1 ?
Statement 1: x > 3
Since we have no information about the value of y, statement 1 is NOT SUFFICIENT
Statement 2: y > 3
Since we have no information about the value of x, statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined
There are infinitely many values of x and y that satisfy BOTH statements. Here are two:
Case a: x = 5 and y = 4. In this case, x/y = 5/4. So, the answer to the target question is
YES, x/y is greater than 1
Case b: x = 4 and y = 5. In this case, x/y = 4/5. So, the answer to the target question is
NO, x/y is not greater than 1
Since we cannot answer the
target question with certainty, the combined statements are NOT SUFFICIENT
Answer: E
