Class 9–10 Maths quiz — 1 November 2026

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

Question 1 · Algebraic identities

If a + b = 12 and ab = 17, what is a² + b²?

Answer: 110. (a + b)² = a² + 2ab + b², so a² + b² = 12² − 2 × 17 = 144 − 34 = 110.

Question 2 · Coordinate geometry

Answer: 13. Distance = √(5² + 12²) = √169 = 13.

Question 3 · Pythagoras theorem

Answer: 87 cm. c² = 60² + 63² = 3600 + 3969 = 7569, so c = 87 cm.

Question 4 · Quadratic equations

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

Question 5 · Trigonometry

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