It is given that the amount of alcohol in the mixture should be 25%.
The given quantity of alcohol is 75 ml.
So, if the quantity of alcohol is 25% then the quantity of water must be 75%.
Let the total solution be x.
Therefore, 25 % of x = 75
x = 300 ml
So, the quantity of water added = 300 - 75
⇒ 225
Hence, option 2 is correct.
