Answer:
ratio of pure lemon juice to water in the homestyle lemon drink is 5 : 19.
Step-by-step explanation:
In order to solve the final ratio of lemon juice to water, let us start by determining the initial ratio of pure lemon juice to water in the first mix. This is done as follows:
Total volume of mixture = 60 liters
initial volume of water = 60 liters
initial volume of lemon juice = 0 liters
1) She removed 15 liters of the water and replaced it with 15 liters of pure lemon juice.
Volume of water = 60 - 15 = 45 liters
Volume of lemon juice = 15 liters
2) She removed 10 liters of the new mixture
Let us convert this amount removed into ratio:
New volumes of water and lemon juice after removing the 10 liters of mixture is calculated as follows:
3) and replaced it with 10 liters of water.
The final ratio of lemon juice to water:
Therefore, the final ratio of pure lemon juice to water in the homestyle lemon drink is 5 : 19.
