Question: 1

Is x an integer?

(1) x is evenly divisible by 1/2

.

(2) x is evenly divisible by 2

  • Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
  • Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
  • BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
  • EACH statement ALONE is sufficient.
  • Statements (1) and (2) TOGETHER are NOT sufficient.

Correct Answer: B

A reminder: The question stem starts with is, so this is a yes or no problem. The first step is to determine whether statement (1) is sufficient, which we can do by trying out some real numbers. If x is 2, which is evenly divisible by 1/2, then the answer would be yes. But if x were 1.5, which is also evenly divisible by 1/2, then the answer would be no. Since you can get either yes or no, statement (1) is not sufficient and you should cross off A and D.

Now let’s move on to statement (2). There are no non-integer numbers that are divisible by 2, so yes is the only possibility. Statement (2) is sufficient, so we can eliminate C and E, and the correct answer is B.
