The present book has been written particularly keeping in mind the problems faced by students studying economics as a paper under CBSE  course. The book will equally serve the purpose of students opting either Arts or Commerce stream. The book is written in a very simple language understanding that it is meant for beginners. The book contains two Parts-A and B. Part-A analysis Microeconomics and Part-B deals with Macroeconomics. The new syllabus containing microeconomics and macroeconomics with eleven units in total have been suitably divided into twenty chapters. At the end of the book, selected basic economic terms have been included under the heading ‘Elementary Economic Terms’. These are the terms most commonly and frequently used in economics and also in real life. The underlying idea is to provide a student general understanding of economics as a subject more clearly and analytically. Past years examination question papers of the NBSE from 1995 onwards have also been incorporated.
