Question

150 gram of sugar solution has 20% sugar in it how much should be added to make it 25% in the solution​

Answer 1

Answer:

Step-by-step explanation:

300g × 40/100 = 120g

So its 120g sugar and 180g water.

Now to make it 50%, we should add 60g sugar. That makes it 180g sugar in 180g water.

Answer 2

Answer:

150 gram of sugar solution has 20% sugar in it. We should add 10 grams to make it 25% in the solution​.

Step-by-step explanation:

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

Sugar = 20/100 × 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:

(100 - 25)/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.
