## Task 3 - 060833

Given are $3000 \mathrm{~g}$ of a 7.2 percent sodium chloride solution in water (i.e., in every $100 \mathrm{~g}$ of the solution, exactly 7.2 g of sodium chloride is contained). By boiling this solution, so much water evaporates that exactly $2400 \mathrm{~g}$ of the concentrated solution remains.

What is the percentage of the resulting solution?
