GMAT Quantitative Comparison Question

In these questions you have to determine if the statements contain the necessary information to answer the questions.


Is x > 4?

1) x < 9

2) x is an integer

A) if statement (1) by itself is sufficient to answer the question, but statement (2) by itself is not;

B) if statement (2) by itself is sufficient to answer the question, but statement (1) by itself is not;

C) if statements (1) and (2) taken together are sufficient to answer the question, even though neither
statement by itself is sufficient;

D) If either statement by itself is sufficient to answer the question;

E) If statements (1) and (2) taken together are not sufficient to answer the question, requiring more data pertaining to the problem.

Solution
Statement (1) implies that x is in between +/- 3 (+/- means positive or negative). Both +3 and -3 are less than 4, so the answer is "NO" (x < 9) and (1) is sufficient, that is NO, x is not greater than 4.

A "NO" answer is equally acceptable as a "YES" answer. It is only necessary that there is sufficient information to answer the question. (2) does not provide any necessary information. The correct response is A, since statement (1) does provide enough information.
