OG - DS - #25

Hello,
The question states:
If i and j are integers, is i + j an even integer.
1) i<10
2) i=j
The answer given is B.

My question is what if both i and j equal 0? That could satisfy both statements and result in answer E, which is what I thought was the correct answer. From what I understand, 0 is an integer and not even. Please explain.

Thanks in advance.

Only 2 ways B is sufficient either e+e or o+o

Since i=j 2nd stmt is sufficient Ans is B

Also

0 is an even number

So e+e=e

Okay thanks, I didn't realize 0 was considered an even #.
I get it now.
Best,
AK

That is correct. Zero is even, though it is neither positive nor negative. Good job everybody!
