The book originally written over 30 years ago has been revised and reprinted several times during the intervening period. It is very heartening to note that there has been an increasing response for the hook from the students of B.A. (Economics Honours), B.Com. (Pass and Honours); M.Com., M.A. (Economics), C.A., I.C.W.A., MBA and other management courses, in spite of the fact that the book has not been revised for quite a long time. Its great pleasure in presenting to the readers, the seventh thoroughly revised and enlarged edition of the book. The book has been revised in the light of the valuable criticism, suggestions and the feedback received from the teachers, students and other readers of the book from all over the country.

Some salient features of the new edition are:

The theoretical discussion throughout has been refined, restructured, rewritten and updated. During the course of rewriting, a sincere attempt has been made to retain the basic features of the earlier editions viz., the simplicity of presentation, lucidity of style and the analytical approach, which have been appreciated by the teachers and the students all over India.

Several new topics have been added at appropriate places to make the treatment of the subject matter more exhaustive and up-to-date.

On persistent demand from the students and the teachers of M.A. (Economies), M.Com. and M.B.A. courses, the New Chapters have been added to make the book more exhaustive and to cater to the syllabi of most of the Indian Universities and professional courses.

STATISTICAL TABLES: (In the Appendix): TABLE XII to TABLE XVI

A number of solved examples, selected from the latest examination papers of various universities and professional institutes, have been added. These are bound to assist understanding and provide greater variety.

Exercise sets containing questions and unsolved problems at the end of each Chapter have been substantially reorganised and rewritten by deleting old problems and adding new problems, selected from the latest examination papers of various universities, C.A., I.C.W.A., and other management courses. All the problems have been very carefully graded and answers to the problems are given at the end of each problem.

An attempt has been made to rectify the errors in the last edition.
