 calculate assessable value:

cum duty whole sale price : 15000

primary packing charges : 800

durable and returnable packing charges : 580

excise duty : 14%

sec n higher educat cess together : 3%

solution: (15000-580)*100/114.42

                 =10,000.

this is how it is done in many books.

my doubt here is why are we deducting the durable n returnable charges from cum duty price....we shud first convert the cum duty price to ex duty n then deduct right....we are supposed to adjust the excludable items to transaction value to arrive at correct A.V...then on it excise duty????
