MANTRA or a helping point will be : As the variables can take any value within the range, more than often the extremes would B the answer that is A or E. So A.5 cannot be formed from 3( something slightly less than 2).. But E.6 can be found as min here will be infinity

Hi ehsan090, You can TEST VALUES to prove which 4 answers ARE possible (and which one is not). We're told that 3 ≥ S ≥ –3, and T > –2. We're asked which of the following CANNOT be the value of S – T.... IF.... S = 1, T = 0, then ST could be 1. Eliminate Answer B. S = 1/2, T = 0, then ST could be 1/2. Eliminate Answer C. S = 1/2, T = 0, then ST could be 1/2. Eliminate Answer D. S = 0, T = 6, then ST could be 6. Eliminate Answer E. There's only one answer remaining... Final Answer: GMAT assassins aren't born, they're made, Rich

Final Answer: GMAT assassins aren't born, they're made, Rich Thanks EMPOWERgmatRichCThis mean anyhow we must use putting values method to come to answer there is no other method exist am I right? Actually I feel it is a little time taken procedure and sometime resulted in panic for me when value are negative specially

Doesn't t>2 mean that it could take assume any value greater than 2? If that's the case, it could be +2 as well which would make the answer 5 possible.

A. 5 B. 1 C. 1/2 D. 1/2 E. –6 For t = 2, 1<=st<=5 For t=1, 2<=st<=4 and so on.. t can take any values and not only integral values. So we can see that st can attain any values <=5 if t>=2 If t>2, st<5.

Hi TheMastermind, You have to pay careful attention to the details of this question  and what it's ultimately asking for. The prompt asks us for what CANNOT be a possible value of (S  T), so proving that four of the answers ARE possible would leave us with the one that is not. You correctly note that T could be +2, so given the possible range of values for S, what COULD (ST) equal...? Any value from +1 to 5, inclusive. "5" is NOT in that range.
