Section 1: Mathematics (40 Questions)
Q1. What is 25% of 200?
A. 25
B. 50
C. 75
D. 100
Answer: B. 50
Rationale: 25% = 0.25 × 200 = 50.
, Q2. Convert 0.75 to a fraction.
A. 1/2
B. 3/4
C. 2/3
D. 4/5
Answer: B. 3/4
Rationale: 0.75 = 75/100 = 3/4 after simplification.
Q3. What is the result of 12.5 × 0.8?
A. 8.5
B. 9.0
C. 10.0
D. 10.5
Answer: C. 10.0
Rationale: 12.5 × 0.8 = 10.0. Multiply as whole numbers (125 × 8 = 1000), then
place the decimal based on total decimal places (2).
Q4. Convert 0.45 to a percentage.
A. 4.5%
B. 45%
C. 450%
D. 0.45%
Answer: B. 45%
Rationale: To convert a decimal to a percent, multiply by 100: 0.45 × 100 = 45%.
, Q5. What is 3/4 as a decimal?
A. 0.25
B. 0.75
C. 0.50
D. 1.33
Answer: B. 0.75
Rationale: 3 ÷ 4 = 0.75. This is a basic fraction-to-decimal conversion.
Q6. A patient requires 500 mg of medication. The available tablets are 250 mg each.
How many tablets should be administered?
A. 1
B. 2
C. 3
D. 4
Answer: B. 2
Rationale: 500 mg ÷ 250 mg = 2 tablets. This is a basic dosage calculation.
Q7. Solve: 45 ÷ 5
A. 7
B. 8
C. 9
D. 10
Answer: C. 9
Rationale: 45 divided by 5 equals 9.
Q8. How many ounces are there in a gallon?
, A. 64
B. 96
C. 128
D. 160
Answer: C. 128
Rationale: 1 gallon equals 4 quarts, 1 quart equals 2 pints, and 1 pint equals 16
fluid ounces. So, 4 quarts × 2 pints × 16 oz = 128 oz.
Q9. A patient receives 500 mL of IV fluid over 4 hours. What is the rate in mL/hr?
A. 100 mL/hr
B. 125 mL/hr
C. 150 mL/hr
D. 200 mL/hr
Answer: B. 125 mL/hr
Rationale: To calculate the rate, divide the total volume by the total time: 500 mL /
4 hours = 125 mL/hr.
Q10. Solve for *x*: 3(x − 4) = 18
A. x = 6
B. x = 8
C. x = 10
D. x = 12
Answer: C. x = 10
Rationale: First, use the distributive property: 3x − 12 = 18. Then, add 12 to both
sides: 3x = 30. Finally, divide both sides by 3: x = 10.
Q11. What is the least common denominator of 1/3 and 1/4?
