AI explanation

The initial mixture contains 7/21 of liquid B, which equals 210 liters, and adding 30 liters of the second mixture contributes another 5 liters of liquid B for a total of 215 liters. The total volume of the new mixture becomes 660 liters, making the final percentage of liquid B equal to (215 divided by 660) multiplied by 100, or 32.58%.
