Question

Sugar solution is composed of 40 grams of sugar and 200 grams of water.
How many grams of sugar must be added to make a 60% sugar solution?

(please answer this with a complete solution)

Answer 1

60% sugar by weight ... 60% of the weight of the solution is sugar

(40 + s) / (240 + s) = 60%

40 + s = 144 + .6 s

.4 s = 104 ... s = 260
