    Hello Sir,

    Following is the question I have a doubt in:

    A company needs 400kg of material Z to fulfil a customer order in one month’s time.
    It currently has no material Z in inventory. The current purchase price of material Z is $20 per kg
    and this is expected to rise to $24 per kg in one month’s time. Material Z is perishable and normally 20% of stored material is lost per month.
    The company expects to have 200kg of material Y in inventory in one month’s time with no
    alternative use other than to sell it for scrap for $18 per kg. The 200kg of material Y could be
    converted into 200kg of material Z in one month’s time at a cost of $4 per kg. Material Y is not
    perishable.

    In the answer,
    The total relevant cost is (200kg x $22) + (200kg x $24) = $9,200
    In the $22, they are even added $18. I did not understand why are we accounting for the scrap value when we can covert Y into Z at $4.

    Thank you in advance!

    It they convert Y and use it then they will be losing the scrap proceeds of $18 that they would otherwise have received. There is therefore an opportunity cost of $18 in addition to the $4 that is spent converting it.

    Have you watched my free lectures on relevant costing? The lectures are a complete free course for Paper PM and cover everything needed to be able to pass the exam well.
