Could you please explain ? Hi, as per question stem x and y are integers but x/y is not integer. This is must be true each statement has to be true to be answer. A. x is odd and y is even.  x = 3 , y = 2  this satisfies the question stem but x =4 and y=3 also satisfies the question stem but y is odd. B. x is odd and y is odd.  x = 3 , y=5 => you can take odd even examples in this too. C. x is even and y is odd. => similar to A D. x<y => x=2 , y=3 or x=4, y=3 E. None of the above> implies none must be true. hope it helps

But, I think the question should mention x and y are POSITIVE integers. If we say that x and y are (just) integers, y can be 0. In that case x/y is Not a Number. Please correct me if I am wrong.

Hi All, This question can be solved by TESTing VALUES (and coming up with examples that DISPROVE each of the wrong answer choices). Since X and Y are INTEGERS and X/Y is NOT an integer, you could quickly come up with a variety of examples of what X and Y COULD be, including.... 1/2, 2/3, 3/2, 4/3, 6/4, 7/3, etc. As such, you can quickly eliminate each of the first 4 answer choices. Final Answer: GMAT assassins aren't born, they're made, Rich

Hi rakaisraka, According to option A, X is odd and Y is even We dont have any such examples through which we can get integer value, then how can we say that it is not always true, please explain

A. x is odd and y is even. B. x is odd and y is odd. C. x is even and y is odd. D. x<y E. None of the above Since we have a "must be true" question and the following details: x,y are integers and \(\frac{x}{y}\) is not an integer. If we can provide an alternative case for each of the answer options,we will end up with Option E as the answer! Consider the following cases 1. x=6(even), y=4(even) and \(\frac{x}{y} = \frac{6}{4}\) is not an integer This eliminates Option A,B, and C. 2. x=4 and y=6. \(\frac{x}{y} = \frac{4}{6}\) and is not an integer This eliminates Option D. Therefore, we are left with Option E(None of the above) and it is our answer!
