If 3 litres has 10% solution of sugar, the sugar comprises 300ml (i.e. a tenth of 3000). If we want 300ml to be 5% then we need a total of 100/5 * 300 = 6,000ml (6 litres). So we need to add 3 more litres of water.
In other words, to halve the percentage of sugar we need to double the total solution from 3 litres to 6 litres.

The chemist will use 100 liters of the 80% acid solution and 100 liters of the 30% acid solution to make a 200-liter solution that is 62% acid. The amount of acid in the 80% solution will be 0.8 * 100 = 80 liters, and in the 30% solution, it will be 0.3 * 100 = 30 liters.
