Problem Solving Set #1


11. Twelve balloons are arranged in a circle as shown. Counting clockwise, every third balloon is popped. C is the first one popped. This continues around the circle until two unpopped balloons remain.
My favorite question was number 11. I like this question because it was more of a fun question. I figured this question out by starting at D because C was the first to be popped. Then, i just kept counting clockwise and crossing out the popped ones until I'm left with 2 remaining balloons, which were E and J
