Chapter-wise important questions for CBSE Class 10 Maths board exam 2027. Focus on high-weightage topics, common mistakes, and scoring strategies.

The CBSE Class 10 Maths board exam 2027 follows the same pattern as recent years: 80 marks theory, 20 marks internal assessment. Knowing which questions are most likely to appear gives you a clear advantage.

This guide covers the most important questions from each chapter, organized by marks and frequency in past papers.

Exam Pattern Overview

  • Section A: 20 MCQs (1 mark each) = 20 marks
  • Section B: 5 questions (2 marks each) = 10 marks
  • Section C: 6 questions (3 marks each) = 18 marks
  • Section D: 4 questions (5 marks each) = 20 marks
  • Section E: 3 case-based questions (4 marks each) = 12 marks

Chapter 1: Real Numbers

High-weightage topics: HCF and LCM using prime factorization, proof that root 2 is irrational.

  • Find the HCF and LCM of 306 and 657 using the prime factorization method. (2 marks)
  • Prove that the square root of 3 is irrational. (3 marks - asked almost every year)
  • Explain why 7 x 11 x 13 + 13 is a composite number. (1 mark MCQ)

Chapter 2: Polynomials

High-weightage topics: Finding zeroes from graphs, relationship between zeroes and coefficients.

  • Find the zeroes of 6x^2 - 3 - 7x and verify the relationship between zeroes and coefficients. (3 marks)
  • If one zero of 2x^2 - 5x + k is reciprocal of the other, find k. (2 marks)

Chapter 3: Linear Equations in Two Variables

High-weightage topics: Graphical method, cross-multiplication method, word problems.

  • Solve the pair of equations: 2x + 3y = 11 and 2x - 4y = -24. (3 marks)
  • For what value of k does the pair kx + 3y = k-3 and 12x + ky = k have no solution? (2 marks)

Chapter 7: Coordinate Geometry

High-weightage topics: Distance formula, section formula, area of triangle.

  • Find the distance between the points A(2, 3) and B(4, 1). (2 marks)
  • Find the coordinates of the point which divides the join of (-1, 7) and (4, -3) in the ratio 2:3. (3 marks)
  • Find the area of the triangle formed by points (2, 3), (4, 7), and (6, 2). (3 marks)

Chapter 13: Statistics

High-weightage topics: Mean (direct, assumed mean, step deviation), median from grouped data.

  • Find the mean of the following frequency distribution using the step deviation method. (5 marks - very commonly asked)
  • Find the median of the following distribution. (5 marks)

Scoring Strategy

  1. Attempt all MCQs first (20 marks in 15 minutes). These are free marks.
  2. Section B and C next (28 marks). Show all steps clearly.
  3. Section D last (20 marks). These take the most time.
  4. Never skip case-based questions (12 marks). They look long but are usually straightforward.
