Target question: Is x > y ?dhirajdas53 wrote:If x and y are integers, is x > y ?
x is a positive multiple of y
xy > 1
Statement 1: x is a positive multiple of y
In other words, y is a divisor of x.
There are several pairs of values that meet this condition. Here are two:
Case a: x = 6 and y = 3, in which case x is greater than y
Case b: x = 3 and y = 3, in which case x is not greater than y
Since we cannot answer the target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: xy > 1
There are several pairs of values that meet this condition. Here are two:
Case a: x = 6 and y = 3, in which case x is greater than y
Case b: x = 3 and y = 3, in which case x is not greater than y
Since we cannot answer the target question with certainty, statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined:
There are several pairs of values that meet the two given conditions. Here are two:
Case a: x = 6 and y = 3, in which case x is greater than y
Case b: x = 3 and y = 3, in which case x is not greater than y
Since we still cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT
Answer = E
