Not that much tough.
Todays AMA paper was a purely conceptual based paper. All questions needs only basic knowledge about the concept.
1) Target costing, life cycle costing,
2) production budget,
3) selecting profitable alternative based on variable and fixed cost,
4) selection of customer order based on total cost incurred to fulfill the order, .
5) Assignment 4*4 matrix row and column knowledge, when zero comes in a row and ascertaining how minimum lines are drawn.
whatever asked was just checking of basic knowledge of concepts, nothing was tough and complecated. we have to apply concept while solving the question.
only Linear programming was bit complecated for me, it involves return and risk adjustment. i didi not attempted that question but It was quite managable and easy paper.
