Cost Accounting-Tulsian PC, Financial management- Tulsian PC, both are easy books with full concepts. But I advise you to refer our inst. material relating to theory part of this subject because its given in easy understood way..Reg. practical problems u refer Tulsian books in addition to module problems and compilations.
Padhuka is exam-oriented. Tulsian book is both knowledge and exam - oriented. Before purchasing, read few chapters from Tulsian available at library or with your friends. If you feel satisfied, go ahead to grab knowledge and ultimate success in your professional life. I am using Tulsian and feel satisfied with it.
