AI explanation

The initial 60-liter mixture contains 40 percent paint B, which equals 24 liters, and 36 liters of paint A. Removing 20 liters of this uniform mixture leaves two-thirds of the original volume, meaning the remaining 40 liters hold exactly 16 liters of paint B and 24 liters of paint A. Adding 20 liters of pure paint B brings the total paint B to 36 liters in a final mixture of 60 liters. The final percentage of paint B is 36 divided by 60 multiplied by 100, which is 60 percent, making Quantity B of 70 percent greater.
