the Sugar have 10 levels of sweetness from X1 = 0 to X10 = 9

[koder]

the Sugar have 10 levels of sweetness from X1 = 0 to X10 = 9
each sort of sugar have its quantity of sells in tonnes/kg,
X1: [0] - 10 tonn
x2: [1] - 9 tonn
x3: [2] - 2 tonn
x4: [3] - 38 tonn
x5: [4] - 1 tonn
x6: [5] - 3 tonn
x7: [6] - 2 tonn
x8: [7] - 42 tonn
x9: [8] - 1 tonn
x10: [9] - 12 tonn

How to calculate the most rational demanded weighted average Sweetness Level i.e.[x] of sugar ?

Unfortunately, i have no clue, maybe i can solve this problem with this algorithm:
quantityX / Σ(quantityX1-X10) - coefficient of weight of each sweetness level
and then... i dont know what to do with sweetness level,
im stuck
, any help please?
