* Original ratio of milk and water was 4:3 * Let the original quantity of milk be 4x * Then original quantity of water was 3x * Total original quantity = 4x + 3x = 7x * 49 litres of water was added * So new quantity of water = 3x + 49 * Ratio is reversed, so new ratio is 3x + 49 : 4x * Using the ratio, (3x + 49) / (4x) = 3/4 * (3x + 49) = 3x * 49 = 2x * x = 24 * Original quantity = 7x = 7 * 24 = 168 litres * New quantity = 4x
