Class 8 Mathematics Chapter 13 – Direct and Indirect Proportion – All Textual Solutions | ASSEB Assam (English Medium)
Class 8 Mathematics Chapter 13 – Direct and Indirect Proportion Complete Textual Questions, Answers, and Solutions (ASSEB / SEBA Assam – English Medium)
Chapter 13, ‘Direct and Indirect Proportion’ (also known as Direct and Inverse Variations), is a highly practical arithmetic chapter in the Class 8 Mathematics curriculum. These complete textual solutions (Class 8 Maths Chapter 13 Textual Question Answers) have been carefully prepared according to the latest syllabus guidelines of the new ASSEB (Assam State School Education Board) and the National Education Policy (NEP). This comprehensive guide includes step-by-step solutions to all textbook exercises, real-world word problems, unitary method applications, and objective-type questions. Brought to you by Ospin Academy, these solutions are designed to be accurate, easy to understand, and fully exam-oriented.
In this chapter, students explore how two quantities depend on each other. In a Direct Proportion, as one quantity increases, the other increases at a constant ratio ($\frac{x}{y} = k$). Conversely, in an Indirect (Inverse) Proportion, as one quantity increases, the other decreases such that their product remains constant ($x \times y = k$). Mastering these concepts is vital for solving real-life problems related to time and work, speed and distance, and resource allocation. Our textual solutions provide clear, step-by-step calculations and table formulations for all textbook problems, along with extra practice questions and MCQs to ensure students are fully prepared for their school examinations.
What you will learn and get from these Textual Solutions:
- Clear methods to identify whether a given situation represents direct or indirect variation.
- Step-by-step table formulation techniques to organize data clearly before solving.
- Application of the direct proportion formula: $\frac{x_1}{y_1} = \frac{x_2}{y_2}$.
- Application of the indirect (inverse) proportion formula: $x_1 \times y_1 = x_2 \times y_2$.
- Important extra variation word problems and latest pattern MCQs designed according to the new syllabus structure.
