I hope that this book will be a favourite among the students and will significantly improve their understanding and confidence. This book is predetermined for the students of the Second Semester Bachelor in Business Administration (Honours) Programme of M.G. University, with effect from the academic year 2024 admission onwards. The objective of this book is to enable the students to understand economic concepts and also help them to prepare for their university examinations. Illustrations are given to explain to the students in a simple way and the technical points involved in working out the problems. I have taken our best efforts to present the subject matter in a simple and understandable manner so that the students can easily learn the terms, concepts and theories that play an important role in the business decision-making process. I gratefully acknowledge the services of our teachers and friends who encouraged and helped us to publish this work. I am confident that both the students and the teachers will find the book extremely useful and rewarding. Constructive and helpful suggestions for improvement of the book will be greatly appreciated and acknowled
