  1. A train travels 360 km in 4 hours. What is its speed in meters per second?

    Answer: 25 m/s

    360 km/4 h = 90 km/h; 90 × 1000/3600 = 25 m/s.

  2. Which property is illustrated by: 3 × (4 + 5) = (3 × 4) + (3 × 5)?

    Answer: Distributive property

    Multiplication distributing over addition is the distributive property.

  3. The area of a rhombus with diagonals 12 cm and 8 cm is:

    Answer: 48 cm²

    Area of rhombus = (d1 × d2)/2 = (12 × 8)/2 = 48 cm².

  4. If 20% of a number is 50, what is 35% of the same number?

    Answer: 87.5

    The number = 50/0.20 = 250; 35% of 250 = 87.5.

  5. The HCF of 48 and 72 is:

    Answer: 24

    Prime factors: 48 = 2⁴×3, 72 = 2³×3²; HCF = 2³×3 = 24.

  6. A cylinder has radius 7 cm and height 10 cm. Its total surface area is: (use π = 22/7)

    Answer: 748 cm²

    TSA = 2πr(h + r) = 2×(22/7)×7×(10+7) = 44×17 = 748 cm².

  7. In a class of 40 students, the ratio of boys to girls is 3:5. How many girls are there?

    Answer: 25

    Girls = 40 × 5/(3+5) = 40 × 5/8 = 25.
