Now, to bring the bleach percentage back to 20%, extra water is added and the amount of bleach remains the same. 16 L of bleach constitutes 20% of the solution → 16/(32 y) = 20/100 → y = 48.

Therefore, 48 litres of water has to be added to the solution if bleach has to be 20% of the whole solution.
