If a > 0 and b > 0 , is a/b an even integer?
1. ab is an even integer
2. b/a is an even integer?
[spoiler]OA: B[/spoiler]
1. ab is an even integer
2. b/a is an even integer?
[spoiler]OA: B[/spoiler]
Statement (1) alone is insufficient.
You can understand by taking a =4, b= 2 and a =2 and b = 4. In both cases, ab = 8 (even) but a/b is even in the former case (a/b = 2) but a fraction in the latter case (a/b = 1/2).
So, a/b may or may not be an even integer.
But, Statement (2) is sufficient because if b/a is an even integer, a/b is 1/(even integer) and thus a fraction. As we see, a/b is NOT AN EVEN INTEGER.
So, the answer to the question is a NO using Statement (2) independently.
(B) is the answer.
