Every month there is sells report in a free market, need to calculate statistics and analyze one type of goods, for example textile of one color (Green for example) with different color gradation (from 10 of Light green to> +10 Darkest green). There are 20 types of green textile with their sells characteristics  V  volume of sells in meters and P  price (which is free market price based on demand/supply in open exchange) How to calculate Most attractive weighted average (so the gradation can be 7.82 for example) Green gradation to buyers, using three data types  digital color, volume and price?

Can you put up a better translation of the original problem? For instance, what does "V  volume of sells in meters" mean? Thank you.

V is the quantity of textile expressed in any unit of length, that is meters, inches, centimeters, and so on.

Well, perhaps someone else here will understand; I sure don't. Suggest you get someone to translate the original to proper English.
