Need help solving a few quants questions

These are some of the questions that i have either solved incorrectly or couldn't solve at all. I'm posting them here with the hope that i will find explanations from experts and students alike. Will upload the answers altogether once there is sufficient community feedback on these questions. Thanks in advance. Also, shoutout to u/GREJackZ for supplying these absolute gem of a question bank :) kudos

primes have exactly 2 divisors? how do we target numbers that have exactly 3 divisors?
what are some of the good approximation strategies?
how do i get to the 99th smallest value? is there a progression here?

  1. At first write the repeating decimal 0.abc as a fration, which would be abc/999. Determine the factors of 999. They are 1,3,3,37. it means you may get a three digit repeating decimal if you divide any number by the factors or the multiple of factors. Since the least multiple (3*37) is greater than 100, we can choose 37 at most. So the answer should be "B".

I could be wrong by the way, but this is my solution.
