Raj Kumar, you may refer book of Parag Sir, but the only problem with it is it is a question bank. You need to refer compiler for most of the solutions of his book. His book is freely available at https://groups.yahoo.com/group/costingbyparaggupta
If you want any solved book, then saxena vashisht is a very good book. Padhuka is also superb but already said that you are not interested in Padhuka
