D. between 0 and -70
E. less than -70

Say y = -100 (y<9)
x = 6
So xy =-600 which is less than -70. Answer is E.

minimum possible value comes when one varible is +ve and another is -ve
Here a range for x is defined and minimum value for x could be 0.0000...1
and no range is defined for Y ..so Y could be any -ve value.say Y=-1000000......0
Making the best ans choice which is the most -ve.
Ans E.

0 < x < 7 , here the minimum value of x will be 1

y < 9 , minimum value will be any extreme number to the left (In the number line ) of 9 , which includes 0 and -ve numbers...

\(+ve * -ve = -ve number\)

So, the minimum value of xy will be a -ve integer...

Thus, the correct answer will be (E) less than -70

Hi All,

We're told that 0 < X < 9 and Y < 9. We're asked for the SMALLEST possible value of (X)(Y). This question is ultimately about Number Properties, so we can answer it in a number of different ways - including by TESTing VALUES or logic.

We know that X must be POSITIVE and Y can be positive (but less than 9), 0 or ANY negative. To make the product (X)(Y) as SMALL as possible, Y would have to be AS NEGATIVE AS POSSIBLE. Multiplying that type of extreme negative value by any positive value would lead to another extreme negative value (re: negative infinity).

Final Answer:
Show Spoiler
E
