Mixture problems combine different solutions or substances to achieve a desired concentration or amount. The general approach: amount of solute in mixture 1 plus amount of solute in mixture 2 equals total solute in the final mixture. For instance, if you mix 5 liters of 10% saline with 3 liters of 20% saline, the total salt is 5×0.1 + 3×0.2 = 0.5 + 0.6 = 1.1 liters of salt in 8 liters total, giving a 1.1/8 = 13.75% saline. Mixture problems appear in chemistry labs, cooking recipes, or business scenarios blending inventory. Familiarity with mixture setups fosters accurate solution mixing and real-world problem resolution.
