GMAT Question of the Day – 8/1/2021

QUESTION

Are the integers a, b, and c consecutive even integers?

STATEMENT 1:

a + 4 = c

STATEMENT 2:

a < b < c

ANSWER SELECTION

ANSWER EXPLANATION

CORRECT ANSWER IS E.

Statement (1): insufficient. This tells us the relationship between a and c, but it tells us nothing about b. Also, it does not let us determine whether a and c are even or odd. Eliminate (A) and (D).

Statement (2): insufficient. The inequality a < b < c does not allow us to determine the differences between the integers. It is possible that a = 2, b = 4, and c = 6; but it is also possible that a = 3, b = 16, and c = 42. Eliminate (B).

Statements (1) and (2): insufficient. We still can’t determine whether or not the integers are even, let alone whether they are consecutive even integers. We could have a = 2, b = 4, and c = 6; but we could just as easily have a = 7, b = 8, and c = 11. The correct answer is choice (E).
