### MCQs on Mathematics

1. What is the value of 2^5 + 3^3?
  - A 35
  - B 38
  - C 43

  - A 22
  - B 26
  - C 30
  - D 34
  - Answer: A 22
  (Calculation: 3(3^2) + 43 - 5 = 39 + 12 - 5 = 27 + 12 - 5 = 34)

3. What is the slope of the line represented by the equation y = 2x + 3?
  - A 2
  - B 3
  - C 0.5
  - D -2
  - Answer: A 2

5. Evaluate the expression: 5! + 3! (Factorial)!
  - A 120 + 6
  - B 126
  - C 120
  - D 130
  - Answer: B 126
  (Calculation: 5! = 120 and 3! = 6; so 120 + 6 = 126)

6. If the perimeter of a square is 36 cm, what is the length of one side?
  - A 6 cm
  - B 9 cm
  - C 12 cm
  - D 15 cm
  - Answer: B 9 cm
  (Perimeter of a square P = 4s; 36 = 4s leads to s = 9 cm)

7. What is 15% of 200?
  - A 25
  - B 30
  - C 35
  - D 40
  - Answer: B 30
  (Calculation: 15/100 × 200 = 30)

8. The sum of two consecutive integers is 45. What are the integers?
  - A 22 and 23
  - B 21 and 22
  - C 23 and 24
  - D 20 and 21
  - Answer: A 22 and 23
  (Let the integers be x and x+1; then x + (x + 1) = 45, leading to 2x + 1 = 45)

9. What is the area of a triangle with base 10 cm and height 5 cm?
  - A 15 cm²
  - B 20 cm²
  - C 25 cm²
  - D 30 cm²
  - Answer: B 25 cm²
  (Area = 1/2× base × height = 1/2× 10 × 5 = 25 cm²)

10. Which of the following equations represents a circle with a radius of 5 centered at the origin?
  - A x^2 + y^2 = 5
  - B x^2 + y^2 = 25
  - C x^2 + y^2 = 10
  - D x^2 + y^2 = 20
  - Answer: B x^2 + y^2 = 25
  (The standard form of a circle's equation is (x - h)^2 + (y - k)^2 = r^2, where r is the radius.)
