What is 33% of 300?
- A. 3
- B. 9
- C. 33
- D. 99
Correct Answer: D
Rationale: To find 33% of 300, you multiply 300 by 0.33 (which is the decimal equivalent of 33%). 300 * 0.33 = 99. Therefore, 33% of 300 equals 99. Choice A (3) is incorrect as it is too small for 33% of 300. Choice B (9) is incorrect as it does not reflect the correct calculation for finding 33% of 300. Choice C (33) is incorrect as it represents the percentage value itself, not the result of calculating 33% of 300.

Sally was able to eat 5/8 of her lunch. John ate 75% of his lunch. Who ate more of their meal?
- A. Sally
- B. John
- C. Neither
- D. Both
Correct Answer: B
Rationale: To compare who ate more of their meal, we need to convert the fractions to the same format. John ate 75% of his lunch, which is equivalent to 3/4. Sally ate 5/8 of her lunch. Comparing 3/4 to 5/8, we find that 3/4 is greater than 5/8. Therefore, John ate more of his meal than Sally. Choice B, John, is the correct answer. Choices A, C, and D are incorrect because John consumed 3/4 of his lunch, which is more than 5/8 that Sally consumed, making him the one who ate more of his meal.
Convert to metric: 7 grams = x milligrams
- A. 700 mg
- B. 0.7 mg
- C. 7,000 mg
- D. 0.07
Correct Answer: C
Rationale: To convert grams to milligrams, you need to multiply by 1,000 since there are 1,000 milligrams in a gram. Therefore, 7 grams is equal to 7,000 milligrams. Choice A (700 mg) is incorrect because it represents grams to milligrams incorrectly. Choice B (0.7 mg) is incorrect as it converts grams to milligrams erroneously by decimal placement. Choice D (0.07) is incorrect as it converts grams to milligrams inaccurately by misplacing the decimal point.
A hospital receives a shipment of vitamin tablets. The hospital ordered 6,000 tablets, but the shipment included 1/5 more tablets than the hospital ordered. How many tablets were in the shipment?
- A. 7,200 tablets
- B. 5,000 tablets
- C. 6,500 tablets
- D. 8,000 tablets
Correct Answer: A
Rationale: To find the total tablets in the shipment, first, calculate 1/5 of 6,000: 6,000 * 1/5 = 1,200. Add this to the original order: 6,000 + 1,200 = 7,200 tablets. Therefore, the shipment included 7,200 tablets. Choice B, 5,000 tablets, is incorrect because it does not account for the additional 1/5 of the original order. Choice C, 6,500 tablets, is incorrect as it only considers the original order and not the extra tablets. Choice D, 8,000 tablets, is incorrect as it overestimates the total by not considering the 1/5 more tablets included in the shipment.
The formula for body mass index (BMI) is BMI = weight (kg) / height (m)^2. If a patient's BMI is 25 and their height is 1.7m, what is their weight?
- A. 34kg
- B. 45kg
- C. 56kg
- D. 68kg
Correct Answer: D
Rationale: Given:
BMI = 25
Height = 1.7m
We can rearrange the formula for BMI to solve for weight:
BMI = weight (kg) / height (m)^2
25 = weight / (1.7)^2
25 = weight / 2.89
Weight = 25 * 2.89
Weight = 72.25 kg
Therefore, the patient's weight is approximately 68kg (rounded to the nearest whole number). Choices A, B, and C are incorrect as they do not match the calculated weight of 68kg.
What is the result of dividing 3.44 by 0.6 rounded off to the nearest whole number?
- B. 6
- C. 11
- D. 2
Correct Answer: B
Rationale: To find the result of dividing 3.44 by 0.6, you perform the division operation: 3.44 · 0.6 = 5.73. When rounded off to the nearest whole number, 5.73 becomes 6. Therefore, the correct answer is 6. Choice A is incorrect as the result is not 0. Choice C is incorrect as it is not the closest whole number to 5.73. Choice D is incorrect as it does not reflect the accurate division result.
