Answers and explanations
Use this answer key to score the Arithmetic Reasoning practice questions. C. Divide $3 by 15. The answer is $0.20, so the correct answer is Choice (C).
 C. Multiply 26 × 11. The other information in the question is irrelevant — it’s there to throw you off. The correct answer is Choice (C). You can immediately eliminate Choice (B) because it isn’t a reasonable answer. Identifying unreasonable answers (through the process of elimination) can help you choose the correct answer choice faster.
 B. Add 45 and 150 to get the cost of the services ($45 + $150 = $195); then multiply the answer by 0.15 (15%) to find the tip. The question asks for the amount of the tip, so the correct answer is Choice (B), $29.25. You can immediately eliminate Choice (D), because the amount is far too high to make sense.
 A. To find the volume of the sandbox, you take length times width times height (V=lwh). Don’t forget that the measurements are for a square sandbox, so you can assume that if the box is 5 feet long, then it’s also 5 feet wide. So 5 × 5 ×1 is 25 cubic feet. Each bag holds 1 cubic foot of sand, and 25 ÷ 1 = 25. Choice (A) is the correct answer. If you were thinking answer Choice (B) sounded good, remember that the answer should make sense. Five cubic feet of sand would not fill a very large sandbox, would it?
 A. Add the two temperatures: 90 + (–20) = 70). Divide 70 by 2 to reach the average temperature, 35. Choice (A) is the correct answer.
