Question: how many liters of water will have to be added to 1125 liters of 45?
Answer: Total quantity of acid present in the resultant solution remains the same; ie., 1125*45/100=506.25 litres. So, % of acid in the resultant solution = 506.25*100/1825 = 27.7% which is more than 25%, but, less than 30%.
