Question #29

Is n equal to 7 ?

(1) n ≥ 7

(2) n ≤ 7


 Explanation

Since each statement, considered independently, merely provides a range that extends infinitely in one direction (greater in statement 1, less than in statement 2), either of these statements taken alone is not sufficient. Combined, however, we can declare the following range for n: 7 ≤ n ≤ 7, which is equivalent to n = 7. The correct answer is (C).
