am glad to present this book, especially designed to serve the needs of the students.
The book has been written keeping in mind the general weakness in understanding
the fundamental concept of the topic. The book is self-explanatory and adopts the
“Teach Yourself” style. It is based on Question-answer pattern. The language of book is Quite
easy and understandable based on scientific approach.
Any further improvement in the contents of the book by making corrections, omission
and inclusion is keen to be achieved based on suggestions from the reader for which the author
shall be obliged.
I acknowledge special thanks to Mr. Rajeev Biyani, Chiarman & Dr. Sanjay Biyani,
Director (Acad.) Biyani Group of Colleges, who is the backbone and main concept provider and
also have been constant source of motivation throughout this endeavour.
I look forward to receiving valuable suggestions from professors of various educational
institutions, other faculty members and the students for improvement of the Quality of the book.
