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

Question 1 · Arithmetic progressions

The first term of an AP is 9 and the common difference is 3. What is its 10th term?

  1. A. 33
  2. B. 37
  3. C. 36 ✓
  4. D. 39

Answer: 36. nth term = a + (n − 1)d = 9 + 9 × 3 = 36.

Question 2 · Probability

A bag holds 4 red, 2 blue and 1 green balls. One ball is picked at random. What is the probability it is red?

  1. A. 4/7 ✓
  2. B. 2
  3. C. 3/7
  4. D. 2/7

Answer: 4/7. Probability = favourable ÷ total = 4/7.

Question 3 · Algebraic identities

If a + b = 7 and ab = 7, what is a² + b²?

  1. A. 35 ✓
  2. B. 42
  3. C. 63
  4. D. 14

Answer: 35. (a + b)² = a² + 2ab + b², so a² + b² = 7² − 2 × 7 = 49 − 14 = 35.

Question 4 · Coordinate geometry

Find the distance between the points (−1, 3) and (13, 51).

  1. A. 50 ✓
  2. B. 49
  3. C. 62
  4. D. 100

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

Question 5 · Mensuration

A cylinder has a radius of 7 cm and a height of 8 cm. What is its volume? (Use π = 22/7)

  1. A. 2464 cm³
  2. B. 1232 cm³ ✓
  3. C. 1386 cm³
  4. D. 1239 cm³

Answer: 1232 cm³. Volume = π r² h = 22/7 × 7 × 7 × 8 = 1232 cm³.
