Most quant questions can be solved via textbook math (lots of algebra), brute force (lots of computations) or via reasoning (number lines, conceptual understanding, etc.) but in my opinion reasoning is the only way to keep your average time per question below 2 minutes.
Thanks!
Hey Avi!
On average, how many approaches or different types of problems exist for each concept tested on the exam?

Hey, are these related to the GMAT?
Yes, this is an official GMAT problem
Also can you please explain how you inferred that 3150 is not a perfect square based on that it is not being multiplied by 1?
Because 1 isn't one of the options in the answer choices.
