CBSE Class 10 Maths Exam : Check Chapter-wise Weightage Paper with Latest Marking Scheme
Check here the chapter-wise weightage distribution for the CBSE Class 10 Maths Exam . Mark the chapters with high weightage to prepare them carefully.CBSE Class 10 Maths Chapter wise Weightage for Board Exam
CBSE Class 10 Maths Paper under the ongoing board exams will be conducted tomorrow – 12th March, . This year board will conduct two papers – Mathematics Standard and Mathematics Basic. On one side, where the students with basic Maths will solve the easy paper, the paper will be a bit tough for the students with standard Maths. In fact, the level of the standard Maths paper will be the same as of previous years’ board examinations. So, here the students with standard Maths will be more anxious about their preparations as they have to score good marks in the paper so that they may continue with Mathematics in the higher classes as well.
In this article, we are providing the in-depth analysis of the latest CBSE sample paper of Class 10 Standard Maths.

This will help students to know the chapters which are important for the exam and need to be prepared carefully.
In CBSE Class 10 Maths Paper , there will be 40 questions divided into four sections – A, B, C and D.
- Section A (1-20) – Objective type questions carrying 1 mark each
- Section B (21-26) – Short answer type questions (Type I) carrying 2 marks each
- Section A (27-34) – Short answer type questions (Type II) carrying 3 marks each
- Section A (35-40) – Long answer type questions carrying 4 marks each
You can check below the number of questions from each chapter asked in all the four sections of Standard Maths Sample Paper:
Chapter Number | Section A | Section B | Section C | Section D | Total Marks |
Chapter 1 | 2 | 1 | 1 | – | 07 |

According to the weightage mentioned above, we can now pick out the chapters which carry high weightage for the annual board examination.
Important Chapters with High Weightage for CBSE Class 10 Maths Board Exam
- Chapter 3 – Pair of Linear Equations in Two Variables = 8 Marks
- Chapter 5 – Arithmetic Progression = 5 Marks
- Chapter 6 – Triangles = 9 Marks
- Chapter 7 – Coordinate Geometry = 6 Marks
- Chapter 8 – Introduction to Trigonometry = 6 Marks
- Chapter 9 – Some Applications of Trigonometry = 6 Marks
- Chapter 13 – Surface Areas and Volumes = 7 Marks
- Chapter 14 – Statistics = 8 Marks
Thus students must focus on these important chapters to prepare them thoroughly so that they may secure high marks in their Maths paper.
Important thing to note here is that this analysis is completely based on the CBSE Class 10 Maths Sample Paper. Board, generally follows the same pattern as of sample papers, in the questions papers of board examinations. So, we can expect the questions in the Maths Paper arranged according to the distribution discussed here.
NCERT Solutions for class 10 Maths Chapter 2- Polynomials
As this is one of the important topics in maths, it comes under the unit – Algebra which has a weightage of 20 marks in the class 10 maths board exams. The average number of questions asked from this chapter is usually 1. This chapter talks about the following,
- Introduction to Polynomials
- Geometrical Meaning of the Zeros of Polynomial
- Relationship between Zeros and Coefficients of a Polynomial
- Division Algorithm for Polynomials
Polynomials are introduced in class 9 where we discussed polynomials in one variable and their degrees in the previous class and this is discussed more in details in class 10. The NCERT solutions for class 10 maths for this chapter discusses the answers for various types of questions related to polynomials and their applications. We study about the division algorithm for polynomials of integers and also whether the zeroes of quadratic polynomials are related to their coefficients.
The chapter starts with the introduction of polynomials in section 2.1 followed by two very important topics in section 2.2 and 2.3
- Geometrical Meaning of the zeroes of a Polynomial – It includes 1 question having 6 different cases.
- Relationship between Zeroes and Coefficients of a polynomial – Explore the relationship between zeroes and coefficients of a quadratic polynomial through solutions to 2 problems in Exercise 2.2 having 6 parts in each question.
Next, it discusses the following topics which were introduced in class 9.
- Division Algorithm for Polynomials – In this, the solutions for 5 problems in Exercise 2.3 is given having three long questions.
