Plz. advice me which is the best book for CA Final Costing. I heard in Collin Drury the concepts are explained brilliantly. And if Collin Drury's book is the best then which book is the second best for thorough preperation of the subject and just like Murlidharan's for MAFA do we have some book completely on theory of CA Final Costing?? Eagerly looking fwd to the reply.
