Question Type: What Is the Value? This question asks how many cars will fit in the parking lot after it is made larger.

Given information from the question stem: The number of cars in each row will be decreased from 40 to 30. However, there will be fewer total rows in the lot as well. In order to answer the question “How many total cars will fit in the entire lot?” you will need to know how many rows times how many cars per row. You already know how many cars per row (30), so this question will hinge on whether you can determine the number of total rows in the new lot.

Statement 1: The new configuration will have 3 fewer rows than the current lot does. However there is no indication of how many rows were originally there. This is not sufficient. Therefore choices A and D are eliminated.

Statement 2: Before the change there are 10 rows of cars. Yet this does not tell you how many rows there will be after the change. Remember: Answer choice B is that “Statement 2 ALONE is sufficient.” This problem is a good opportunity to practice looking at Statement 2 alone and forgetting what you learned from Statement 1. Since Statement 2 alone is also not sufficient, choice B is eliminated.

Together: The statements allow for the calculation that there are 7 rows after the changes to the parking lot. 7 rows @ 30 cars per row = 210 cars. This is sufficient and the answer is C.
