Class 9–10 Maths quiz — 5 November 2026

Questions and answers from this day. Play today's quiz to build your streak.

Question 1 · Trigonometry

Find the value of sin 30° × cos 60° + tan 45°.

  1. A. 5/4 ✓
  2. B. 2
  3. C. 1/2
  4. D. 3/2

Answer: 5/4. Use sin 30° = ½, cos 60° = ½, tan 45° = 1, sin 90° = 1 and cos 0° = 1. sin 30° × cos 60° + tan 45° = 5/4.

Question 2 · Coordinate geometry

Find the distance between the points (3, −4) and (17, 44).

  1. A. 51
  2. B. 62
  3. C. 672
  4. D. 50 ✓

Answer: 50. Distance = √(14² + 48²) = √2500 = 50.

Question 3 · Quadratic equations

What is the larger root of x² − 4x + 3 = 0?

  1. A. 3 ✓
  2. B. 2
  3. C. 4
  4. D. 1

Answer: 3. x² − 4x + 3 = (x − 3)(x − 1) = 0, so the roots are 3 and 1. The larger is 3.

Question 4 · Linear equations

If x + y = 26 and x − y = 4, what is x?

  1. A. 16
  2. B. 26
  3. C. 15 ✓
  4. D. 30

Answer: 15. Add the two equations: 2x = 26 + 4 = 30, so x = 15.

Question 5 · AP sums

Find the sum of the first 20 terms of the AP that starts at 2 with common difference 5.

  1. A. 970
  2. B. 1010
  3. C. 1040
  4. D. 990 ✓

Answer: 990. Sum = n/2 × (2a + (n − 1)d) = 20/2 × (4 + 95) = 990.
