Question

300 grams of sugar solution contains 40% sugar. how much sugar should be added to make it 50% sugar solution

Answer 1

Now, Percentage of sugar=amount of sugar/amount of solution

let x be the amount of sugar present in the given solution.

40/100=x/300

(4*300)/10=x

120 gram =x.

50% percent of sugar solution =50/100=0.5

let a be the amount of sugar to be added.

0.5=(120+a)/(300+a)

150+(a/2)=120+a

a-(a/2)=30

(a/2)=30

a= amount of sugar should be added to make it 50 percent sugar solution = 60 gram .

Hope this will help you.
