- The original mixture contains 25 liters, with 30% spirit. This means it has 7.5 liters of spirit (0.3 * 25 = 7.5).

- The remaining 70% is water, which is 17.5 liters of water.

- When you add 5 liters of water, the total amount of water becomes 22.5 liters (17.5 + 5).

- The total volume of the new mixture is now 30 liters (25 + 5).

- The amount of spirit remains unchanged at 7.5 liters.

- To find the new percentage of spirit: \((7.5 \ \text{liters of spirit} / 30 \ \text{liters total}) \times 100 = 25%\).

- Correct Answer: Option 3 - 25%
