  1. The sum of interior angles of a hexagon is:

    Answer: 720°

    Sum = (n − 2) × 180° = (6 − 2) × 180° = 720°.

  2. Which of the following fractions is between 3/5 and 4/5?

    Answer: 7/10

    3/5 = 0.6 and 4/5 = 0.8; 7/10 = 0.7 lies between them.

  3. A number when divided by 56 gives remainder 29. What remainder does the same number give when divided by 8?

    Answer: 5

    56 is divisible by 8; so remainder = 29 mod 8 = 29 − 24 = 5.

  4. The probability of getting a head when a fair coin is tossed twice is:

    Answer: 3/4

    P(at least one head) = 1 − P(no head) = 1 − 1/4 = 3/4.

  5. If a:b = 2:3 and b:c = 4:5, then a:b:c is:

    Answer: 8:12:15

    Make b common: a:b = 8:12 and b:c = 12:15; so a:b:c = 8:12:15.

  6. The volume of a cube whose surface area is 96 cm² is:

    Answer: 64 cm³

    6a² = 96 → a² = 16 → a = 4 cm; volume = 4³ = 64 cm³.

  7. Which pedagogical approach best helps primary students understand the concept of fractions?

    Answer: Using paper folding and equal-sharing activities

    Concrete manipulatives like paper folding build conceptual understanding of fractions.
