If you have time then Go for P.C.Tulsian. It has variety of questions, past year questions as well to grab the concept. A perfect self study book.
But if you have less time you can refer Rajesh makkar,it gives conceptual clarity in concise form. You can combine it with Practice manual and compiler as well.
Both writer's books are available for costing and FM. And I have presumed that you are going to do self study.
