Official Solution:


Statement (1) by itself is sufficient. S1 tells that the mentioned pair is (1, -1). The product of these numbers is \(-1 * 1 = -1\).

Statement (2) by itself is insufficient. Consider \((1, -1)\) and \((1, 3)\).


Answer: A

0 is even, not odd.

But can't I use (-3,3) as the consecutive odd integers. If yes then the answer would be 9 and then A will not be sufficient. please help.

Consecutive odd or even integers are those with common difference of 2. So, for example, -1 and 1 or 9 and 11. -3 and 3 are not consecutive odd integers.

so statement one you are saying is sufficient right? statement one says either one of the numbers are negative. hence why cannot 1,3 be used as consecutive integers which fails the statement?

Hi,

The way this question is worded is kind of confusing. When they are asking what is the product, I am assuming a certain numerical value is what needs to be solved for.

The question is fine. Yes, it's asks for a product, and (1) gives exact numerical answer: The product of these numbers is −1∗1=−1 .

If I understand it correctly, this particular question is essentially asking for the value of the product, right?

Bunuel.

How can we assume only 2 numbers?

I mean we can have the series as -1, 1, 3, 5 etc as well.. and so by this logic, A would not be sufficient.

if we include zero in the terms, then we get a conclusive answer.. but Zero is not Odd.

Bunuel: If I assume the question to be asking whether the product of two numbers is positive or negative, Statement 1 is sufficient. But if I interpret the question to be asking what the value is, then Statement 1 is not sufficient as the product of two unknowns can be different.

What is the correct interpretation? Value or positive/negative?

Thanks,
Megha.

The question asks about the value of the product of two integers, which, from (1) turns out to be -1.
