75 g of sugar solution has 30% sugar in it. Then, the quantity of sugar that should be added to the solution to make the quantity of the sugar 70% in the solution, is
A.125 g
B.100 g
FeedbackSugar in original solution = (75 x 30) / 100 = 22.5 g Let x g of sugar be mixed According to the question {(22.5 + p)/(75 + p)} x 100 = 70 2250 + 100p = 75 × 70 + 70p 2250 + 100p = 5250 + 70p 30p = 5250 – 2250= 3000 => p = 3000/30 = 100g
C.120 g
D.130 g
