Preface to The Ninth Edition

I am pleased to present the Ninth Edition (Two Colours) of this standard treatise on large size paper to enable the reader to handle the book comfortably. The warm reception which the previous editions and reprints of this book have enjoyed all over India and abroad, has been a matter of great satisfaction to me.

The entire book has been thoroughly revised ; besides adding a large number of “Additional/Typical Worked Examples” in various chapters. It is hoped that the book in this comprehensive and complete form will prove to be of immense use for the students preparing various ‘Universities’ and Competitive Examinations (e.g., UPSC, GATE etc.).

The author’s thanks are due to his wife Ramesh Rajput for extending all cooperation during preparation and proof reading of this revised manuscript.
