PAX PAX Numerical Reasoning 2 — Questions and Answers
Question 1: A bag of IV solution holds 1,000 mL and drips at 125 mL/hour. How many hours will it last?
- 6 hours
- 7 hours
- 8 hours (Correct answer)
- 9 hours
Correct answer: 8 hours
1,000 ÷ 125 = 8 hours.
Question 2: If a number is increased by 20% and the result is 84, what was the original number?
- 63
- 70 (Correct answer)
- 72
- 68
Correct answer: 70
Let x be the original: 1.20x = 84, so x = 84 ÷ 1.20 = 70.
Question 3: What is the greatest common factor (GCF) of 36 and 48?
- 6
- 12 (Correct answer)
- 18
- 9
Correct answer: 12
The factors of 36 include 12 (36 = 12 × 3) and 12 also divides 48 (48 = 12 × 4), making 12 the GCF.
Question 4: A patient needs to take 3 tablets per day for 14 days. How many tablets are needed in total?
- 36
- 38
- 42 (Correct answer)
- 48
Correct answer: 42
3 tablets × 14 days = 42 tablets.
Question 5: What is the value of 3³ + 4²?
- 37
- 43 (Correct answer)
- 25
- 91
Correct answer: 43
3³ = 27 and 4² = 16; 27 + 16 = 43.
Question 6: A sequence is: 100, 91, 82, 73, ___. What comes next?
- 66
- 64 (Correct answer)
- 63
- 62
Correct answer: 64
Each term decreases by 9, so 73 − 9 = 64.
