In the bottled soft drink industry, a mixture of sugars is used as a sweetener, basically glucose and fructose dissolved in water. Consider the mixing process as shown in the figure in which three streams are poured in certain proportions to obtain a solution containing $14\mathrm{.}3\%$ fructose and $16\mathrm{.}6\%$ glucose. to$.$ Determine the mass ratio D$1/$D$2.$ b$.$ If the solution obtained in the previous point must raise the fructose concentration to $25\%$ through evaporation, how much water must be removed per $100$ kg of original solution $($P$)$
