Acc to question
this mixture contain 18kg spirit and 2kg water
as per the question, we have to add water to make the concentration equal to 25%
so the amount of spirit will remain unchanged in the final mixture
spirit = 18 kg which represent 75% of the final mixture (as remining 25% is water)
applying formula for percentage
75%=18kg
then 100% would be (18*100)/75
=24
which means we have to add 4kg of water.
