Question
A glass contains a certain quantity of vodka. After
removing 8 liters of vodka and replacing it with lime, this process is repeated twice more—first, taking out 10 liters of the mixture and replacing it with lime, and then, taking out 12 liters of the mixture and replacing it with lime. If the initial quantity of vodka in the glass is 80 liters, what is the final quantity of vodka?ÂSolution
ATQ Votka = 80 × (1 – 8/80) × (1 – 10/80) × (1 – 12/80) = 53.55 litersÂ
