  1. What is the gradient (slope) of the line passing through (2, 3) and (6, 11)?

    Answer: 2

    Slope = (11 − 3) / (6 − 2) = 8 / 4 = 2.

  2. A car travels 180 km in 3 hours. What is its average speed?

    Answer: 60 km/h

    Speed = distance ÷ time = 180 ÷ 3 = 60 km/h.

  3. Which of the following is NOT a property of a parallelogram?

    Answer: All angles are 90°

    All angles being 90° is a property of a rectangle, not all parallelograms.

  4. Factorize: x² − 9

    Answer: (x − 3)(x + 3)

    x² − 9 is a difference of two squares: (x − 3)(x + 3).

  5. What is the volume of a cuboid with length 5 cm, width 4 cm, and height 3 cm?

    Answer: 60 cm³

    Volume = l × w × h = 5 × 4 × 3 = 60 cm³.

  6. If the ratio of boys to girls in a class is 3:5 and there are 24 boys, how many girls are there?

    Answer: 40

    24 boys = 3 parts, so 1 part = 8; girls = 5 × 8 = 40.

  7. Evaluate: √(144 + 25)

    Answer: 13

    144 + 25 = 169, and √169 = 13.
