Question: A mixture of two types of tea contains 40% of tea A and 60% of tea B. If 20 liters of tea B is added, what will be the new percentage of tea A if the total mixture becomes 100 liters?
Options:
Correct Answer: 40%
Solution:
Initial volume of tea A = 0.4 * 80 = 32 liters. Total volume after adding tea B = 100 liters. New percentage of tea A = (32/100) * 100 = 32%.
