1 litre of water is added to 5 Il tres of alcohol-water solution con taining 40% alcohol strength. The strength of alcohol in the new solution will be

Options

A. 0.3
B. 0.33
C. 33 `2/3` %
D. 33 `1/3` %

Answer

To solve the problem, we need to determine the strength of alcohol in the new solution after adding 1 liter of water to the existing 5 liters of alcohol-water solution that contains 40% alcohol.

### Step-by-Step Solution:

1. **Calculate the amount of alcohol in the original solution:**
- The original solution is 5 liters with 40% alcohol.
- Amount of alcohol = 40% of 5 liters = (40/100) * 5 = 2 liters.

2. **Determine the total volume of the new solution:**
- We add 1 liter of water to the original 5 liters of solution.
- Total volume of the new solution = 5 liters + 1 liter = 6 liters.

3. **Calculate the strength of alcohol in the new solution:**
- The amount of alcohol remains the same, which is 2 liters.
- Strength of alcohol in the new solution = (Amount of alcohol / Total volume of solution) * 100
- Strength of alcohol = (2 liters / 6 liters) * 100 = (1/3) * 100 ≈ 33.33%.

### Final Answer:
The strength of alcohol in the new solution will be approximately **33.33%**.
