No sir. Everything in the above diagram is set up in terms of Total weights of solutions (water + sugar) and not the weight of water alone. The individual weights of sugar or sugar are implied in the percentage concentrations (5%, 0%, and 20%). Therefore x= Total weight of 20%
solution = 60 oz. Not 48 oz., which represents the weight of water alone in the 20% solution
Fast Technique. Thanks to GMATClub!
I've done mixtures questions before, and maybe this is just me not getting it because my brain is all curdled up right now, so forgive me for my ignorance.
Shouldn't x = 48 oz (which is the amount of water in it)?
And therefore, 3x = 144 oz?
I too get the 1:3 ratio. But maybe I'm missing something here.
+1 Kudos me - I'm half Irish, half Prussian.
