Weightage kya hai sare chapters ek hi to book me hai. Chapters ke liya separate books nahi hai.

**Weightage for each chapter of maths**

The weightage for each chapter of mathematics can vary depending on the specific curriculum, syllabus, or exam pattern. However, I can provide you with a general breakdown of some common chapters and their weightage based on a typical curriculum. It's important to note that this breakdown is not exhaustive and may vary in different education systems. Here is a detailed explanation of the weightage for each chapter of maths:

**1. Number Systems:**
- Weightage: 5-7%
- This chapter includes topics like rational and irrational numbers, real numbers, laws of exponents, and square roots.
- It forms the foundation for various mathematical concepts and helps in understanding the properties and operations involving numbers.

**2. Algebra:**
- Weightage: 10-12%
- Algebra includes topics such as polynomials, linear equations, quadratic equations, arithmetic progressions, and factorization.
- It is a fundamental branch of mathematics that deals with symbols and the manipulation of these symbols to solve equations and represent mathematical relationships.

**3. Coordinate Geometry:**
- Weightage: 6-8%
- This chapter involves the study of the relationship between geometric figures and their coordinates on a plane.
- It includes topics like distance formula, section formula, and the concept of a straight line.
- Coordinate geometry helps in understanding the graphical representation of equations and solving problems related to geometrical figures.

**4. Geometry:**
- Weightage: 15-18%
- Geometry covers topics like lines and angles, triangles, polygons, circles, and three-dimensional figures.
- It focuses on the properties and relationships of shapes and figures in both two and three dimensions.
- Geometry is an essential branch of mathematics as it helps in understanding spatial relationships and solving problems related to shapes and figures.
