Hi AAPL,

We're told that in a certain shipment of T-shirts, 20% are red - and of those red shirts, 30% are size small. There are 366 red, small T-shirts. We're asked for the total number of T-shirts in the original shipment. This question can be solved in a couple of different ways, but you might find it fastest to just to the 'math' involved (although the answer choices are 'spread out' enough that you can stop working at a certain point....).

Since 30% of the 20% of the total are red, small shirts, we can set up the following equation:

(Total)(.2)(.3) = 366
(Total)(.06) = 366
(Total)(6) = 36,600

At this point, we know that '6 times' the total = 36,000+, so the correct answer has to be greater than 6,000. There's only one answer that matches:

Final Answer: E
