SAT QOTD - Oct 25th

I recently downloaded SAT QOTD onto my smartphone and am having a blast. The Oct 25th math question was especially fun! Join me, guys, we can compare notes. You can view the questions online or download the app through the College Board website, http://sat.collegeboard.org/practice/sat-question-of-the-day.

Tip : When I see a pie slice type question, I remind myself how many degrees are in a circle and imagine myself slicing a pie. ie A pie cut in 4 would be 90deg each slice. If I further cut the pie to make 8 slices, each would then be 45deg.

So, how did you approach this difficult math question? How long did it take you to find your solution?  If you saw this question on the SAT, how much time would you spend on it and why?
