Book for costing

You have options as follows-

1. If you want  Fully Conceptual, depth starts from Zero Book Then I think it is Cost Accounting, B. K. Bhar, Academic publishers, Kolkata. It is really for self-Study.                                                                                                                                                                                                                                                                                        

                                              OR

2. You may opt for P. C. tulsian, TMH. It is good for Both Basic Concepts and Practice

                                              OR

3. Take ICWAI study material Cost and Management Accounting i.e. Now Cost Accounting and Financial Management uder New Syllabus-2012 (Inter). It is for Easy, Basics, short way Study but Practice Examples are not  in large number.

Whether you reffer for Option 1 or 2 or 3, Lastly you must have Suppliment exam material like Padhuka, RTP etc.

I think it would be better to opt for Option 1(B. K. Bhar) + Exam suppliment like padhuks & RTP etc

padhuka its a exam oriented book with decent concept see nov 12 paper direct question of transfer pricng and capital budgeting with probabilty from there 23 marks and most of them say it was a very tough paper 

theory  only from practice manual

Go for Padhuka & Practice manual..
