According to question,
300g of 25% solution contains solute = (300 x 25) / 100 = 75g
&
400g of 40% solution contains solute = (400 x 40) / 100 = 160g
Total solute = 75 + 160 = 235g
As given in the question, total solution =300 + 400 = 700g
Percentage of solute in the final solution = (235 x100) / 700 = 33.5%
Percentage of water in the final solution = 100 - 33.5 = 65.5%

Answer:
Mass of sodium chloride (solution) = 36 g
Mass of water (solvent) = 100 g
Total mass of solution = 100 + 36 = 136 g
Mass percentage of solution= mass of solute/mass of solution X 100
=36/136x100
= 26.47%
