Answer 1

hope it will help you

Answer 2

Answer:

40 grams

Step-by-step explanation:

Let x be the grams of sugar has to be added to make it 40 percent solution

Initial concentration of sugar = 20 g

Initial concentration of water = 60 g

New amount of solution = x+60

ATQ

$\frac{x}{x+60}=\frac{40}{100}$

$x=0.4x+24$

$x=40$

Hence 40 grams of sugar has to be added to make it 40 percent solution
