Question:

If the ratio of brown cars to blue cars in a certain parking lot is 2:3, how many brown cars are in the lot?

(1) There are 15 blue cars in the lot.

(2) There are 25 cars total in the lot.

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

Correct Answer: D

Explanation:

When we evaluate statement (1), we can tell that there are 10 brown cars in the lot, because that’s the only number that would give us a ratio of 2:3 if there are 15 blue cars. So we can eliminate B, C, and E.

Taking statement (2) alone, we can tell that we have 15 blue and 10 brown cars in the lot, because those are the only numbers that would add up to 25 and give a ratio of 2:3. So either statement is sufficient on its own, which means D is the correct answer.
