^I think Schoy's solution is how you're suppose to 'see it' in order to break it down in less than 2 minutes. My grudge with the GMAT is that some of the wordings REALLY throw me off. I spend a good portion trying to decipher what they're really trying to say. And when I look at the explanation for the answer, it's quite 'simple' as Schoy's solution. Of course it's only simple when you see how they did it.
