Question

A sweets manufacturer uses 15% sugar solution to immerse sweets in it. The customers
complain about the lack of sweetness in the sweets. So, the manufacturer evaporates 30 liters
of water to make it 20% sugar solution. What was the initial volume of the sugar solution before
30 liters of water was evaporated?​

Answer 1

Answer:

Step-by-step explanation:

Let the mass of solution =100g

Mass of sugar =15g

Mass of water =100−15=85g

On heating some amount water is disappeared and let the new amount of solution is (X)g, which contain 40% sugar equal to 15g

X×  

100

40

​  

=15

x=37.5g

After heating mass of solution is =37.5g

Mass of water = Mass of solution - Mass of water

=37.5−15=22.5

Amount of water disappeared on heating

=(85−22.5)=62.5g
