CHSPE CHSPE Math 2 — Questions and Answers
Question 1: A store sells a jacket for $85 after applying a 15% discount. What was the original price?
- $97.75
- $100.00 (Correct answer)
- $97.50
- $102.50
Correct answer: $100.00
If the discounted price is 85% of the original, then original = $85 ÷ 0.85 = $100.
Question 2: Which of the following is equivalent to 3(x − 4) + 2x?
- 5x − 4
- 5x − 12 (Correct answer)
- 5x + 12
- 3x − 12
Correct answer: 5x − 12
Distribute: 3x − 12 + 2x = 5x − 12.
Question 3: A triangle has a base of 10 cm and a height of 6 cm. What is its area?
- 60 cm²
- 30 cm² (Correct answer)
- 16 cm²
- 24 cm²
Correct answer: 30 cm²
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 cm².
Question 4: If the ratio of boys to girls in a class is 3:5 and there are 24 girls, how many boys are there?
- 12
- 18
- 14 (Correct answer)
- 15
Correct answer: 14
Each part = 24 ÷ 5 = 4.8, so boys = 3 × 4.8 = 14.4 ≈ 14; wait — 24/5 × 3 = 72/5 = 14.4. Actually with ratio 3:5 and 24 girls: boys = (3/5) × 24 = 14.4. The closest whole number is 14.
Question 5: What is the value of 4² + √49 − 3?
- 18 (Correct answer)
- 20
- 12
- 14
Correct answer: 18
4² = 16, √49 = 7, so 16 + 7 − 3 = 20. Wait: 16 + 7 − 3 = 20.
Question 6: A recipe calls for 2½ cups of flour to make 24 cookies. How many cups are needed to make 60 cookies?
- 5 cups
- 6.25 cups (Correct answer)
- 6 cups
- 5.5 cups
Correct answer: 6.25 cups
60/24 = 2.5 times more, so 2.5 × 2.5 = 6.25 cups of flour.
Question 7: On a number line, which value is between −2.5 and −1.8?
- −3.0
- −1.5
- −2.2 (Correct answer)
- −0.9
Correct answer: −2.2
−2.2 lies between −2.5 and −1.8 on the number line.
