Brix value of sugarcane at maturity is

Brix value is a measure of the soluble solids content of a solution.
Brix value can be calculated by dividing the dissolved solids by the sum of the dissolved solid plus water, all multiplied by 100.
$${\text{Bx}} = \frac{{\left( {{\text{Ds}} \times {\text{100}}} \right)}}{{\left( {{\text{Ds}} + {\text{100}}} \right)}}$$
And Brix value of sugar cane is in between 16 - 18.
