Hi boomgoesthegmat,
The answer choices to this question are so 'spread out' that you can use a bit of 'brute force' math and some logic to get to the correct answer relatively quickly.
The question asks us what percent of 30 is 150....
Well, 100% of 30 is 30, so we're clearly looking for a larger percent than 100%.
200% of 30 is 60, but we're asked to find a percent that equals 150, so we need one that's far greater than 200%.
There's only one answer left...
Final Answer: E
