DU B.COM (SEM-3): Business Mathematics and Statistics  (English, Paperback, J. K. Sharma)

There are a lot of mistakes in the book. The answers are not correct and neither is the method clearly displayed. So many questions do not show the proper steps to proceed with. Also, log tables required are not given with the book. Although I have given a 4 star review, the book clearly has a lot of room for improvement.
