A container initially held 8 liters of vinegar. After
removing a certain amount of vinegar, 2.4 liters of water was added to the container. As a result, the ratio of vinegar to water in the container became 7:3. How much vinegar was removed from the container?Solution
Let x litres of vinegar was taken out.
The quantity of water in the mixture = 2.4 litres
So, (8 - x)/(2.4) = 7/3
=> 24 - 3x = 16.8
=> 3x = 7.2
=> x = 2.4 litres
