Can anyody advice me on this. Let us take an example :

Say: the Question stem says :- Is X > 7 ?

Statement 1: produces a value for X= 8 as an answer

Statement 2: produces a value for X= 11 as an answer

Will the staments be considered as contradicting each other ? Is it necessary that both the statements produce the same value for an answer. Although both the statements gives a value for X > 7 but they do not match.

Should the student consider it a calculation mistake ? Is it necessary in the GMAT that both the statements gives us the same value for the answer. Please post your comments and advice on this . Please mention whether it is necessary that both the statements produce the same value for an answer.

I am talking about a yes or no question like the above in which both the question gives the answer yes but the values produced is different as in above both gives the value of X greater than 7 but one is giving it as 8 and the other as 11.
Also when the answer given by both the statements is no should the value be the same, for example in the above question if Statement 1) gives a value 4 and statement 2) gives a value 3 is that Okay ?
