CLT Quantitative Reasoning 1 — Questions and Answers
Question 1: If a shirt originally costs $80 and is discounted 25%, what is the sale price?
- $60 (Correct answer)
- $55
- $65
- $70
Correct answer: $60
25% of $80 is $20. Subtracting the discount: $80 - $20 = $60.
Question 2: What is the probability of rolling a sum of 7 with two dice?
- 6/36 or 1/6 (Correct answer)
- 1/12
- 1/36
- 7/36
Correct answer: 6/36 or 1/6
Six combinations produce a sum of 7: (1,6),(2,5),(3,4),(4,3),(5,2),(6,1). Out of 36 possible outcomes, probability = 6/36 = 1/6.
Question 3: If a car travels 180 miles in 3 hours, what is its average speed?
- 60 mph (Correct answer)
- 45 mph
- 90 mph
- 54 mph
Correct answer: 60 mph
Average speed = distance ÷ time = 180 ÷ 3 = 60 mph.
Question 4: What is 15% of 240?
- 36 (Correct answer)
- 24
- 30
- 48
Correct answer: 36
15% × 240 = 0.15 × 240 = 36.
Question 5: If x + 5 = 12, what is the value of 2x?
- 14 (Correct answer)
- 12
- 7
- 17
Correct answer: 14
x + 5 = 12, so x = 7. Therefore 2x = 2(7) = 14.
