Which book to refer for cma inter paper - 8 cost accounting

Hi Friends;

Though the book provided by the institute is very good but I still feel that the problem questions are less in the book. On this forum people are suggesting for the book from Saxena and Vashist.

I see the below books authored by them and all are Sultan Chand & Sons Publications

01. Advanced Cost and Management Accounting 02. Cost Accounting Problems and Solutions 03. Essentials of Cost Accounting 04. Cost Accounting 05. Advanced Cost and Management Accounting Problems and Solutions

Out of these which book I should refer.

Awaiting your response

Thanks
