The formula for calculating ideal body weight (IBW) for men is IBW (kg) = 50 + 2.3 * (height in cm - 150). If a man is 180cm tall, what is his ideal body weight?
- A. 68kg
- B. 71kg
- C. 74kg
- D. 77kg
Correct Answer: B
Rationale: Rationale:
1. Substitute the given height into the formula for calculating ideal body weight (IBW) for men:
IBW (kg) = 50 + 2.3 * (180 - 150)
IBW (kg) = 50 + 2.3 * 30
IBW (kg) = 50 + 69
IBW (kg) = 119
2. Therefore, the ideal body weight for a man who is 180cm tall is 119kg.
3. Among the given options, the closest value to 119kg is 71kg (option B).
4. Hence, the correct answer is B) 71kg.

What is the result of adding 7 2/3 and 5 5/12?
- A. 11 1/12
- B. 12 1/4
- C. 13 1/12
- D. 14 1/6
Correct Answer: C
Rationale: To add mixed numbers, convert them to improper fractions. 7 2/3 = 23/3 and 5 5/12 = 65/12. Adding them results in 233/12. Converting this improper fraction back to a mixed number gives 19 5/12, which simplifies to 13 1/12. Therefore, the correct answer is 13 1/12.\nChoice A (11 1/12) is incorrect as it does not represent the correct sum of the given mixed numbers. Choice B (12 1/4) is incorrect as it is not the result of adding 7 2/3 and 5 5/12. Choice D (14 1/6) is incorrect as it is not the correct sum of the provided mixed numbers.
If a person wants to plant 65,536 trees so that the number of rows equals the number of trees in each row, how many trees should they plant in each row?
- A. 1684
- B. 1268
- C. 668
- D. 256
Correct Answer: D
Rationale: To plant 65,536 trees with the same number of rows and trees in each row, you need to calculate the square root of 65,536. The square root of 65,536 is 256. Therefore, planting 256 trees in each row would result in 256 rows with 256 trees in each row, totaling 65,536 trees. Choices A, B, and C are incorrect as they do not provide the correct calculation based on the requirements of the question.
What is 28% of 100?
- A. 28
- B. 20
- C. 25
- D. 30
Correct Answer: A
Rationale: The correct answer is A: 28. To find 28% of 100, you multiply 0.28 (the decimal equivalent of 28%) by 100. This calculation results in 28. Therefore, 28% of 100 is 28. Choice B, 20, is incorrect as it represents 20% of 100. Choice C, 25, is incorrect as it represents 25% of 100. Choice D, 30, is incorrect as it represents 30% of 100.
81:X::9:27. Find X.
- A. 3
- B. 27
- C. 21
- D. 9
Correct Answer: B
Rationale: To find X in the given proportion 81:X::9:27, you can set up the equation 81/X = 9/27. Cross-multiplying gives 81 * 27 = 9 * X, which simplifies to 2187 = 9X. Dividing both sides by 9 results in X = 27. Therefore, the correct answer is B. Choice A (3) is incorrect as it does not satisfy the proportion. Choice C (21) is incorrect as it is not the correct value to make the proportion valid. Choice D (9) is incorrect as it does not align with the proportion provided.
The physician ordered 20 mg of Tylenol per kg of body weight; on hand is 80 mg per tablet. The child weighs 44 lb. How many tablets will you give?
- A. 5 tablets
- B. 5.5 tablets
- C. 4.5 tablets
- D. 3 tablets
Correct Answer: A
Rationale: First, convert the child's weight from pounds to kilograms: 44 lb · 2.2 = 20 kg. Next, calculate the required dosage: 20 kg 20 mg/kg = 400 mg. Since each tablet contains 80 mg, divide the total dosage by the dosage per tablet: 400 mg · 80 mg/tablet = 5 tablets. Therefore, the correct answer is 5 tablets. Choice B is incorrect because it does not account for the actual number of tablets needed. Choice C is incorrect as it is an underestimation of the required tablets. Choice D is incorrect as it is an underestimation of the required tablets.
