The overwhelming response to the previous edition has encouraged us to present this new, enriched and enlarged edition, with much more to read, practise and grasp. The feedback received from our readers and the pattern of questions asked in various competitive exams in the current years have been the major factor kept in mind while preparing this book. Consequently, many new chapters like Geom­etry, Fundamentals of Trigonometry, Linear and Quadratic Equations, Progressions, Polygons etc. have been incorporated. Special emphasis has been laid on short-cut approach to solving the questions as early as possible. The reference of questions asked in various competitive examinations, collected from various examinees on their memory basis, have been given. It is very much hoped that the new subject matter will instil a confidence among the readers and help them achieve their goal. I convey my gratitude to the entire management and staff of S.Chand & Co. Ltd. for taking great pains and interest in presenting the book in the present form.
