That sure is a nice problem you've got there.... but what are your thoughts? What have you tried? Please (re)-read the Read Before Posting thread that's stickied at the top of each subforum and comply with the rules found therein. Specifically, please share with us any and all work you've done on this problem, even the parts you know for sure are wrong. Thank you.

Assuming you need a hint to even get started, let \(x\) be the number of liters of 30% sugar solution used and \(y\) be the number of liters of 10% sugar solution used. What, then, does the quantity \(x + y\) represent? Based on the problem text, what must this value be? Where does that lead you?
