    Pro Rata number of garments?

    I have to manufacture 1000 garments. Each garment will require on average 2mts of fabric. I need to make a number of garments in different sizes. 100 in size 10, 500 in size 12 and 400 in size 14. The total amount of fabric available is 2000 mts.

    How do I pro rata the number of garments of each size to be made, if the average amount of fabric required per garment is 1.5 mts?

    This sounds suspiciously like an exam question...

    Don't get lost in the numbers, look at what's important - how much material do you have for reference, how much do you have in reality. Find the difference between the two, apply it to your reference figures.

    This is a technical IT How to do it forum... not a maths problem solving forum

    Thank you for the info elsiegee40, this is there first time I've used this forum.

    LosOjos, this is not an exam question. Thanks for your input. The amount of material is 2000 mts. That remains constant. What needs to change is the number of garments for each size when the amount of fabric required to manufacture each garment changes.

    Ask a textiles forum? Surely they would be better placed.

    How do I pro rata the number of garments of each size to be made, if the average amount of fabric required per garment is 1.5 mts?
    Being sensible for once I'm not sure I understand the question. You have two different values for the average material used per garment. Also what do you mean by "pro rata the number of garments"? If each garment will require on average 2m of fabric (as first stated) then in my mind it is 2000m/2m = 1000 garments able to be made. You have an order for 1000 garments (the total of all the sizes) so you are OK. If each garment will require on average 1.5m of fabric (as stated at the end) then again in my mind it is 200m/1.5m = 1333.33 garments. So you will have fabric over, or better you have a margin for error and spoilage.

    Otherwise just cleanse it with fire. It's for the best

    Hi TechMonkey,

    Yes you are right, the number of extra garments that could be made is 333. The question is, how would you spread the extra amount in the same proportion as the original amounts? "Pro Rata" ie 100 in size 10, 500 in size 12 and 400 in size 14.

    As regards to the fire, that is next week. (Very old joke)

    This reminds me of the Jeb's Jobs video:
