PSAT Math Multiple-Choice Question 578: Answer and Explanation

Question: 578

What are the values of m and n in the table above

• A. m = 4 and n = 8
• B. m = 8 and n = 26
• C. m = 2 and n = 13
• D. Cannot determine based on the given information.

Correct Answer: C

Explanation:

(C) The value of m must be 2. All of the trucks and SUVs must add up to a total of 45, and there are 43 of the other truck/SUV types: 43 + 2 = 45. The value of n must be 13. The total of all the different types of vehicles must add up to 200. The numbers in the last column show a total of 178 + 9 = 187 and 187 + 13 = 200.
