You have to add 30 litres of water At the beginning you have 20 L of 10% solution, so it consists of 2L of acid and 18 L of water. Now you have to calculate the amount of water to add to change the solution to 4%. To do this you have to solve equation: 2/(20+x)=4/100 The equation comes from the fact that the amount of acid is unchanged (2L) and the sum of water and acid is increased by x (added water) 2/(20+x)=2/50 40+2x=100 2x=100-40 2x=60 x=30
