**A tank contains 200 liters of a solution that is 15% salt. How much pure water must be added to dilute it to a 10% salt solution?** How much pure water must be added to a 200-liter saltwater solution containing 15% salt to reduce its concentration to 10%? This common question arises in daily life, industry, and even educational contexts—driven by growing interest in water quality, sustainability, and resource efficiency. In regions where water scarcity or cost efficiency impacts decision-making, understanding how to safely dilute concentrated salt solutions can matter more than ever. As people seek reliable, transparent data to guide household maintenance, industrial processes, or environmental practices, this calculation becomes surprisingly relevant. --- ### Why A tank contains 200 liters of a solution that is 15% salt.
