**drwls**, Monday, July 6, 2009 at 6:46pmYour original 10%, 200 g mixture has 180 g of water and 20 g of sucrose. Let x be the number of grams of sucrose you need to add. The reqiuorement is

(20 + x)/180 + x) = 0.20

Solve for x

**Reiny**, Monday, July 6, 2009 at 7:14pmBut, aren't we adding the x grams to the original 200 ?

so I would say:

20+x = .2(200+x)

for x = 25
