CBSE Class 10 Maths Important Questions 2027 - Chapter Wise

In short: The most important questions for CBSE Class 10 Maths 2027 come from Trigonometry, Statistics, Coordinate Geometry, and Quadratic Equations, which together carry over 40 marks. Focus on NCERT examples, previous year repeats, and case-based questions from Section E to maximize your score on the 80-mark theory paper.

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. For a complete understanding of how marks are distributed, check our CBSE Class 10 Maths chapter-wise marks weightage guide.

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.

Frequently Asked Questions

Which chapters are most important for CBSE Class 10 Maths 2027?

Trigonometry (Chapters 8-9), Statistics and Probability (Chapters 13-14), and Algebra chapters like Quadratic Equations and Arithmetic Progressions carry the highest marks. Together, these chapters account for over 40 marks out of 80.

How many times should I solve previous year papers for Maths?

Aim to solve at least 5 to 8 previous year papers under timed conditions. This helps you identify repeating question patterns, improve your speed, and build confidence for the actual exam.

Are NCERT examples enough for the CBSE Class 10 Maths board exam?

NCERT examples and exercises cover roughly 70% of what appears on the board paper. For a 90+ score, supplement NCERT with previous year questions and sample papers. The remaining 30% tests application of the same concepts in slightly different formats.

How should I prepare for the case-based questions in Section E?

Case-based questions in Section E carry 12 marks and are usually based on real-life applications of Maths concepts. Practice reading data from tables, graphs, and word problems. These questions test comprehension more than calculation, so they are often easier than they look.

What is the best revision strategy for Maths before the board exam?

Keep a formula sheet for all chapters and revise it daily. In the last 2 weeks, focus on solving full-length papers rather than reading theory. For more detailed revision tips, see our best revision strategy before board exams guide.
