Question: What is the perimeter of a rectangle with length 10 cm and width 7 cm?
Answer: 34 cm
Rationale: Perimeter = 2(length + width) = 2(10 + 7) = 2 × 17 = 34 cm.
Question: If a shirt costs $40 and is discounted by 20%, what is the sale price?
Answer: $32
Rationale: Discount = 40 × 0.20 = $8; Sale price = 40 − 8 = $32.
Question: Solve for x: 3x + 4 = 13.
Answer: x = 3
Rationale: 3x + 4 = 13 → 3x = 9 → x = 3.
Question: What is the area of a circle with radius 5 cm? (Use π ≈ 3.14)
Answer: 78.5 cm²
Rationale: Area = πr² = 3.14 × 5² = 3.14 × 25 = 78.5 cm².
Question: If you earn $12/hour and work 25 hours, what is your total pay?
Answer: $300
Rationale: Total pay = 12 × 25 = $300.
, Question: What is 2/3 as a decimal?
Answer: 0.6667
Rationale: 2 ÷ 3 ≈ 0.6667 (rounded to four decimal places).
Question: What is the mean of the numbers 3, 5, 7, 9, 11?
Answer: 7
Rationale: Mean = (3 + 5 + 7 + 9 + 11) ÷ 5 = 35 ÷ 5 = 7.
Question: If a car travels 180 miles in 3 hours, what is its average speed?
Answer: 60 mph
Rationale: Speed = distance ÷ time = 180 ÷ 3 = 60 mph.
Question: What is the simple interest on $2000 at 4% annual rate for 3 years?
Answer: $240
Rationale: Simple interest = Principal × Rate × Time = 2000 × 0.04 × 3 = $240.
Question: What is the volume of a cube with side length 4 cm?
Answer: 64 cm³
Rationale: Volume = side³ = 4³ = 64 cm³.
Question: If 3x − 5 = 10, what is x?
Answer: x = 5
Rationale: 3x − 5 = 10 → 3x = 15 → x = 5.
Question: What is 25% of 120?
Answer: 30
Rationale: 25% of 120 = 0.25 × 120 = 30.
Question: What is the circumference of a circle with diameter 8 cm? (Use π ≈ 3.14)
Answer: 25.12 cm
Rationale: Circumference = π × diameter = 3.14 × 8 = 25.12 cm.

Answer: y = 3
Rationale: 4y + 3 = 15 → 4y = 12 → y = 3.
Question: What is the median of the numbers 2, 4, 6, 8, 10?
Answer: 6
Rationale: Ordered: 2, 4, 6, 8, 10; median is the middle value (6).
Question: Convert 1.5 hours to minutes.
Answer: 90 minutes
Rationale: 1.5 × 60 = 90 minutes.
Question: If a triangle has base 5 cm and height 6 cm, what is its area?
Answer: 15 cm²
Rationale: Area = (1/2) × base × height = (1/2) × 5 × 6 = 15 cm².
Question: What is the compound interest on $1000 at 5% annually for 2 years? (Use A = P(1 +
r)^n)
Answer: $102.50
Rationale: A = 1000(1 + 0.05)² = 1000 × 1.1025 = 1102.50; Interest = 1102.50 − 1000 =
$102.50.
Question: If 6x = 18, what is x?
Answer: 3
