Question:
A 60 litres of alcohol and water contains 20 litres of alcohol. How much alcohol must be added to produce a solution of 50% alcohol?
Answer:
20 litres.
Explanation:
Given,
- Total solution = 60 litres
- Amount of alcohol = 20 litres.
Let's assume the required amount of alcohol must be added is ‘x’ litres.
∴ New amount of alcohol = (x + 20) litres.
∴ New solution = (x + 60) litres.
According to the question,
New amount of alcohol is 50% of the total new solution.
Solving for ‘x’ :-
∴ Required answer: 20 litres

Question :
A 60 litres of alcohol and water contains 20 litres of alcohol. How much alcohol must be added to produce a solution of 50% alcohol?
Given :
- Total solution = 60 litres
- Alcohol in solution = 20 litres
To Find :
- Amount of alcohol must be added to produce a solution of 50% alcohol.
Solution :
Let “x” litre alcohol must be added to produce 50% alcohol. So, the new amount of solution and alcohol will be :
- ➝ Alcohol = (x + 20) litres
- ➝ Solution = (60 + x) litres
Now, According to the question :
Hence, 20 litres of alcohol must be added to produce a solution of 50% alcohol.
