Answer:

From the given percentage, let's work out the amount of sugar in the solution.

Sugar = 20/100 x 150 = 30 grams

Amount of water = 150 - 30 = 120

The ratio of water to sugar in the 150 grams solution is given as:

120/30 4:1

= 4:1

Let the amount of sugar added to the solution be x.

The new ratio is given by:

(10025)/25= 75/25 = 3:1

So we have that:

120/(x +30) = 3/1

120 = 3(x + 30)

120 = 3x + 90

120 90 3x

30 = 3x

x = 30/3 = 10

So, we should add 10 grams of sugar to make it 25% in the solution.
