The book provides quantitative tools to tackle real-life problems of the corporate world. It has been designed to prepare MBA students to take a straight plunge into the streams of Mathematics, Statistics and Operations Research for business purposes. It is a three-in-one textbook that covers the fundamentals of these streams, and perhaps a textbook with the largest number of fully-solved case studies from diverse areas of management, like marketing, finance, HR and operations in a single volume. Its rich Appendix offers many utility tables in mathematics and statistics, and other supplementary topics that are not directly covered by the MBA curriculum, but form the backbone of their study. The book contains minimal of text as it leans heavily on explaining the concepts through application-oriented examples and solved problems. The end-of-chapter exercises have been provided with answers to all problems and hints, wherever necessary.
