In the xy-coordinate plane, what are the x-coordinates of the four vertices of square JKMN ?
(1) J and M are on the x-axis, and K and N are on the y-axis.
(2) The center of the square is at the origin.

(A) Statement 1 alone is sufficient, but statement 2 alone is not.
(B) Statement 2 alone is sufficient, but statement 1 alone is not.
(C) Both statements together are sufficient, but neither alone is sufficient.
(D) Each statement alone is sufficient.
(E) Neither statement is sufficient, even when combined.
(1) J and M are on the x-axis, and K and N are on the y-axis.
(2) The center of the square is at the origin.

Target question: What are the x-coordinates of the four vertices of square JKMN ?
When I SCAN the two statements (always scan the statements before performing any calculations!), I see that neither statement provides any information about the size of the square.
So, I’m going to head straight to……
Statements 1 and 2 combined
There are infinitely many squares that satisfy BOTH statements. Here are two:
Since the 4 vertices of the smaller square are different from the 4 vertices of the larger square, we can conclude that there is no way we can answer target question with certainty
So, the combined statements are NOT SUFFICIENT
Answer: E
Cheers,
Brent

Consider the square in the following diagram-
J and M are on X-axis and K, and N are on the Y-axis. The center of the square is at the origin. Also, length of the diagonal is '2a'.
We can draw infinite such squares by assigning 'a' different values. Hence, x-coordinates of J and M can have infinite values.
