Solution

Let us suppose that solution A contains 25% of solute X and solution B contain 40% of solute X. The two solutions are mixed together to form a solution C.
The total mass of the solution = 300 g (Solution A) + 400 g (solution B) = 700 g
Mass of solute X in solution A = 25% of 300g = (25x300) / 100 = 75 g
Mass of solute X in Solution B = 40% of 400g = (40x400) / 100 = 160 g
Total mass of solute in Solution C = 75 g + 160 g = 235 g
Mass % of solution C = (235 / 700) x 100 = 33.6 %
