Hi chayma,

How often have you actually tried TESTing VALUES and ended up facing the specific situation that you are concerned about? Keep in mind that some questions will actually require that you TEST more than one value (or set of values) based on how the prompt is worded - and since DS questions are all about whether the answer to the question is consistent or inconsistent, you HAVE to TEST multiple values to make sure that you have the correct answer.

When TESTing VALUES, as long as you are following whatever 'restrictions' the prompt describes, if only one answer matches what you are looking for, then that answer is the correct answer.

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

I have a problem with plugging in numbers , i always think that it won't work if i try different values. How do i make sure that it would be the same result everytime ?


Dear chayma,
begin you journey from that tasks, take into consideration what restrictions are ?
In our case:
If Q is an odd number and the median of Q consecutive integers is 120, what is the largest of these integers?

So, you can start to put any ODD numbers, and the upshot will be the same.

3: 119, 120, 121
5: 118, 119, 120, 121, 122
etc.

Then substitute in the equations to find right one

(A) (Q - 1)/2 + 120
(B) Q/2 + 119
(C) Q/2 + 120
(D) (Q + 119)/2
(E) (Q + 120)/2
