How many litres of water will have to be added to 1125 litres of the 45% solution of acid so that the resulting mixture will contain more than 25% but less than 30% acid content?

Explanation

To solve the problem step by step, we need to find out how many liters of water should be added to 1125 liters of a 45% acid solution so that the resulting mixture has an acid concentration of more than 25% but less than 30%.

### Step 1: Determine the amount of acid in the original solution
The amount of acid in the original solution can be calculated as follows:

\[ \text{Amount of acid} = \text{Volume of solution} \times \text{Concentration of acid} \]
