MATHEMATICS SECTION

1. What is 15% of 80?

A) 10

B) 12

C) 15

D) 18

E) 20

CORRECT ANSWER: B) 12

RATIONALE: To find 15% of 80, multiply 80 by 0.15. 80 × 0.15 = 12. Percentages are
calculated by converting the percentage to a decimal (15% = 0.15) and multiplying
by the whole number.



2. Solve: 3x + 5 = 20

A) x = 3

,B) x = 4

C) x = 5

D) x = 6

E) x = 7

CORRECT ANSWER: C) x = 5

RATIONALE: Subtract 5 from both sides: 3x = 15. Divide both sides by 3: x = 5.
Check: 3(5) + 5 = 15 + 5 = 20 ✓



3. If a patient receives 250 mL of medication over 2 hours, what is the rate in
mL/hour?

A) 100 mL/hour

B) 125 mL/hour

C) 150 mL/hour

D) 175 mL/hour

E) 200 mL/hour

CORRECT ANSWER: B) 125 mL/hour

RATIONALE: Rate = Total volume ÷ Time in hours. 250 mL ÷ 2 hours = 125 mL/hour.
This is a fundamental calculation for IV flow rates in nursing.



4. What is 3/4 + 1/8?

A) 4/12

B) 4/8

C) 7/8

D) 8/4

E) 5/12

,CORRECT ANSWER: C) 7/8

RATIONALE: Convert 3/4 to eighths: 3/4 = 6/8. Add: 6/8 + 1/8 = 7/8. When adding
fractions, you must have a common denominator.



5. A medication costs $45 for a 30-day supply. What is the cost per day?

A) $1.25

B) $1.50

C) $1.75

D) $2.00

E) $2.50

CORRECT ANSWER: B) $1.50

RATIONALE: Divide total cost by number of days: $45 ÷ 30 days = $1.50 per day.
This type of calculation is useful for understanding medication expenses.



6. If the ratio of nurses to patients is 1:4, and there are 12 nurses, how many
patients are there?

A) 24

B) 36

C) 48

D) 60

E) 72

CORRECT ANSWER: C) 48

RATIONALE: If the ratio is 1:4, and there are 12 nurses, multiply both parts by 12:
(1×12):(4×12) = 12:48. Therefore, there are 48 patients.

, 7. Convert 0.75 to a percentage.

A) 7.5%

B) 57.5%

C) 65%

D) 75%

E) 85%

CORRECT ANSWER: D) 75%

RATIONALE: To convert a decimal to a percentage, multiply by 100. 0.75 × 100 =
75%. Alternatively, 0.75 = 75/100 = 75%.



8. What is 20% of 150?

A) 20

B) 25

C) 30

D) 35

E) 40

CORRECT ANSWER: C) 30

RATIONALE: 20% of 150 = 0.20 × 150 = 30. Percent calculations are essential for
dosage and concentration problems in healthcare.



9. Solve: 2x - 4 = 10

A) x = 5

B) x = 6

C) x = 7

D) x = 8
