Solution

Given that a solution is obtained by mixing $300$ g of $25 %$ solution and $400$ g of $40 %$ solution by mass.

Total mass of solution $= 300 + 400 = 700$ g

Mass of solute $= 0.25 \times 300 + 0.40 \times 400 = 75 + 160 = 235$ g

Mass percentage of solution $= \frac{235}{700} \times 100 = 33.6 %$

Hence, the mass percentage of the resulting solution is 33.6%
