(A) x − z (B) x − y (C) y − x (D) z − y (E) z − x Irespective of the signs, X and Z will be the farthest, so the numeric value of their difference will be maximum and since x is the larger of two, xz will be positive.. A

(A) x − z (E) z − x Absolute value of both the options are same. (But the sign of x , y and z is not mentioned....Is it really going to make any difference to this question !!! )
Option A.

Option A. It is not known whether x, y and z are positive or negative, but it doesn't matter. We know that x is larger than z, so xz will be positive and zx will be negative. We don't need to know the values or the signs. To double check, pick some values (keeping in mind that x > y > z): x=10, y=4, z=1 Now the answer choices become: (A) x − z = 9 (B) x − y = 6 (C) y − x = 6 (D) z − y = 3 (E) z − x = 9 Option (A) is the greatest. A for Ali, obviously. If you want to be super double extra sure, because you're not convinced that the sign of the numbers doesn't matter, then pick some wild numbers and see if it makes a difference. x=10, y=0, z=a bazillion Now the answer choices become: (A) x − z = a bazillion + 10 (B) x − y = 10 (C) y − x = 10 (D) z − y = a bazillion (E) z − x = a bazillion  10 Still (A)

Substituting numbers for variables will work.
Moreover, I do not think this is a 600700 level question but rather a sub600 question.

(A) x − z (B) x − y (C) y − x (D) z − y (E) z − x There are no restrictions on the values of x, y, and z. So we can pick any three numbers that fulfill the inequalities mentioned in the question. Let us take x = 3, y = 2 and z = 1 (A) x − z = 3  1 = 2(B) x − y = 3  2 = 1(C) y − x = 2  3 = 1(D) z − y = 1  2 = 1(E) z − x = 1  3 = 2Correct answer  A

So, numbers are in ascending order: z, y, x
So, x  y will be the largest.
As chetan said yesterday, we need to keep in mind that sign will be taken care of. So, no need to worry:).

(A) x − z (B) x − y (C) y − x (D) z − y (E) z − x Basically, the question tells us that x>y>z If the smallest number is subtracted from the largest number, we get the greatest number. X is the largest number and z is the smallest number; hence, xz is the greatest number. A is the answer

well imo you don't have to care about negatives. Remember its not a ds questions, so it its works with positives its enough to answer the question (at least in my view, but maybe I'm missing something?) Anyway of course it also works with negative

as x is greatest number and z is smallest number so xz would be highest number. Answer A
