Sample Questions and Answers (Class 8 Maths)

  1. What is the value of 2x + 5 when x = 3?

    • Answer: Substituting x = 3, we get 2(3) + 5 = 6 + 5 = 11.

  2. Solve for x: 5x – 3 = 22.

    • Answer: Add 3 to both sides: 5x = 25. Now, divide both sides by 5: x = 5.

  3. Find the area of a triangle with base 6 cm and height 4 cm.

    • Answer: Area = 1/2 * base * height = 1/2 * 6 * 4 = 12 cm².

  4. What is the perimeter of a rectangle with length 8 cm and width 5 cm?

    • Answer: Perimeter = 2 * (length + width) = 2 * (8 + 5) = 26 cm.

  5. Solve for y: 3y + 4 = 19.

    • Answer: Subtract 4 from both sides: 3y = 15. Now divide by 3: y = 5.

  1. What is the value of the expression 4x² + 3 when x = 2?

    • Answer: Substitute x = 2: 4(2)² + 3 = 4(4) + 3 = 16 + 3 = 19.

  2. If the sum of two consecutive integers is 15, find them.

    • Answer: Let the integers be x and x + 1. So, x + (x + 1) = 15. Solving, we get x = 7 and x + 1 = 8.

  3. Find the simple interest on a principal of ₹1000 at a rate of 5% for 3 years.

    • Answer: Simple Interest = (Principal * Rate * Time) / 100 = (1000 * 5 * 3) / 100 = ₹150.

  4. The ratio of boys to girls in a class is 3:4. If there are 21 boys, how many girls are there?

    • Answer: 3/4 = 21/x. Cross-multiply and solve for x: x = (21 * 4) / 3 = 28 girls.

  5. What is the volume of a cube with side 3 cm?

    • Answer: Volume = side³ = 3³ = 27 cm³.

  6. Solve for z: 4z – 7 = 9.

    • Answer: Add 7 to both sides: 4z = 16. Now divide by 4: z = 4.

  7. Find the perimeter of a square with side length 5 cm.

    • Answer: Perimeter = 4 * side = 4 * 5 = 20 cm.

  1. Solve for x: 2x + 8 = 18.

  4. Solve for y: 6y – 4 = 32.

    • Answer: Add 4 to both sides: 6y = 36. Now divide by 6: y = 6.

  5. Find the area of a circle with radius 7 cm (use π = 22/7).

    • Answer: Area = π * r² = (22/7) * 7² = 154/7 = 22 cm².

  1. Solve for x: 3x – 4 = 11.

    • Answer: Add 4 to both sides: 3x = 15. Now divide by 3: x = 5.

  2. What is the perimeter of a triangle with sides 3 cm, 4 cm, and 5 cm?

    • Answer: Perimeter = 3 + 4 + 5 = 12 cm.

  3. Solve for x: 5x + 6 = 26.

    • Answer: Subtract 6 from both sides: 5x = 20. Now divide by 5: x = 4.
