This book is intended to be a comprehensive and standard textbook for undergraduate students of Microeconomics. Apart from providing students with sufficient study material for examination purpose, it aims at making them understand economics. An effort has been made to explain abstract and complex microeconomic theories in a simple and lucid language without sacrificing analytical sophistication. The subject matter has been structured in a systematic manner without leaving gaps for the readers to fill in. Though the approach is non-mathematical, simple algebra has been used to give a concrete view of economic concepts and theories and to show the applicability of economic theories in decision making.
