Answer 2

Answer:

Answer will be 100 gm.

Step-by-step explanation:

75 gm of sugar solution has 30% sugar. then

sugar in original solution = (75*30)/100 = 22.5 g

(note: (22.5 / 75) * 100 = 30 )

let x g of sugar be mixed to make the quantity of sugar 70%,so

(22.5+x) / (75+x) *100 =70

=>2250+100x = 5250+70x

=>100x-70x = 5250-2250

=>30x = 3000

=>x = 100 gm
