E = 48

48 = XY or -x*-y; as x is not negativ it is would be only possible if xy = 48

AS x<=4 --> y MUST be >=12

Not possible

Hi All,

For most Test Takers, the easiest way to answer this question is to think about the 'limits' that are placed on X and Y, then find the answer that doesn't 'fit' within those limitations. Alternatively, you can eliminate the 4 answers that are possible - and the one that's left will be the correct answer.

We're told that 0≤ X ≤4 and Y <12. We're asked which of the following CANNOT be the value of (X)(Y).

IF...
X = 1, Y = -2, then XY = -2

X=0, Y = 1, then XY = 0

X = 1, Y = 6, then XY = 6

X = 4, Y = 6, then XY = 24

Since those 4 answers are possible, the last answer is not...

Final Answer:

GMAT assassins aren't born, they're made,
Rich

0<=x<4
y<12
xy<12 * 4
xy<48

Hence : answer E
