As i have completed MBA, i will suggest the following books
Principles of Marketing by Philip Kotler,
Management by Danny Samson & Richard L. Daft
Fundamentals of Financial Management by Van Horne
But for the management i found
"Strategic Management and Business Policy" by Thomas L. Wheelen & David Hunger the best book. It is very comprehensive & having all basic and strategic management concepts in a sequence covered in just 300 pages. So it is MUST READ Book for Business Administration.
Cheers
