NCERT Solutions for Class 9 Mathematics (Ganita Manjari)

Old vs New Class 9 Maths Textbook: Where Each Topic Went

Ganita Manjari is not the old textbook with new chapter names. The topics have been regrouped and taught in a different order, and three chapters are completely new. Use this table to find where a familiar topic from the old book now appears.

Chapters that are new to Class 9

a) Ch 8: Predicting What Comes Next: Exploring Sequences and Progressions covers explicit and recursive rules for sequences, arithmetic progressions and geometric progressions. Arithmetic progressions were earlier taught in Class 10.

b) Ch 9: Propositions and their Converses introduces mathematical statements and their converses, which is the groundwork for writing proofs.

c) Ch 11: The World of Algorithms teaches step-by-step procedures and algorithmic thinking. There was no equivalent in the old book.

How to use these solutions

a) Part 1 (Chapters 1 to 8): each chapter's solutions are on a single page.

b) Part 2 (Chapters 9 to 14): solutions are split into separate pages for each exercise set, the solved examples, and the end-of-chapter exercises, so you can go straight to the exercise you are working on.

c) Old textbook solutions: these are still useful for extra practice on topics that carried over, such as circles and quadrilaterals. The chapter numbers and exercise questions do not match Ganita Manjari, though, so do not use them for Ganita Manjari homework.
