Question 1 of 5

What is the average of the numbers 14, 73, and 7?

Correct Answer: D

Rationale: To find the average of a set of numbers, you add them up and then divide by the total number of values. In this case, 14 + 73 + 7 = 94. Then, 94 divided by 3 (total numbers) gives 31.33. Therefore, choice D is correct. Choices A, B, and C are incorrect because they do not correctly calculate the average of the given numbers. A, B, and C are calculated as 14 + 73 + 7 divided by 3, which leads to incorrect averages.

Question 2 of 5

Convert 5 3/4 to a decimal. Round to the nearest tenth.

Correct Answer: C

Rationale: To convert 5 3/4 to a decimal, first convert the mixed number to an improper fraction: 5 3/4 = (4*5 + 3)/4 = 23/4. Then, divide the numerator by the denominator to get the decimal: 23 ÷ 4 = 5.75. Rounding to the nearest tenth gives 5.8, which is choice C. Choices A, B, and D are incorrect because they do not accurately represent the decimal equivalent of 5 3/4 rounded to the nearest tenth.

Question 3 of 5

Mr. Brown bought 5 cheeseburgers, 3 drinks, and 4 fries for his family, and a cookie pack for his dog. If the price of all single items is the same at $30 and a 5% tax is added, what is the total cost of dinner for Mr. Brown?

Correct Answer: C

Rationale: The correct answer is C: $17. Rationale: 1. Mr. Brown bought 5 cheeseburgers, 3 drinks, and 4 fries, totaling 12 items. 2. Each item costs $30, so the total cost before tax is $30 x 12 = $360. 3. A 5% tax is added to the total cost: $360 x 0.05 = $18. 4. Adding the tax to the total cost gives us $360 + $18 = $378. 5. Therefore, the total cost of dinner for Mr. Brown is $378. 6. Among the choices, $17 is the closest amount to the calculated total cost of $378, making it the correct answer. Summary: A: $16 - Incorrect, as it is lower than the calculated total cost. B: $16.90 - Incorrect, as it is lower than the calculated total cost. C: $17 - Correct, as it is

Question 4 of 5

If 1 pound equals 453.59 grams, how many grams would a 7 lb. baby weigh?

Correct Answer: A

Rationale: To find the weight of a 7 lb. baby in grams, multiply 7 (lbs) by the conversion factor 453.59 (grams/lb). 7 lbs x 453.59 = 3175.13 grams. Therefore, the correct answer is A. Choice B (4000 grams) is incorrect as it does not consider the precise conversion factor. Choice C (4535 grams) is incorrect as it simply multiplies 7 by 1000. Choice D (3500 grams) is incorrect as it uses a different conversion factor.

Question 5 of 5

After taking several practice tests, Brian improved the results of his GRE test by 30%. Given that the first time he took the test Brian answered 150 questions correctly, how many questions did he answer correctly on the second test?

Correct Answer: D

Rationale: To find out how many questions Brian answered correctly on the second test, we first calculate the 30% increase from his initial score of 150 questions. 30% of 150 is 45, so his new score is 150 + 45 = 195 questions. Therefore, the correct answer is D (195). Choice A (105) is incorrect because it is less than the initial score of 150. Choice B (120) is incorrect because it does not account for the 30% increase. Choice C (180) is incorrect as it is the result of adding 30% to the initial score, not the final score after the increase.
