94% of Chief Rose's income last year came from his salary. The rest came from working on details. If he earned $9,600 on detail, what was his total income?

  1. $145,000
  2. $160,000
  3. $170,000
  4. $120,000
  5. $118,600
Explanation
Answer: B - $160,000.

In this case, 94% is a pretty lousy number to work with. 6% is much better.

If 6% equals $9,600, then 1% = $1,600. Thus, 100% is equal to $160,000.

Key Takeaway: This question is all about speed. By finding easy numbers to work with, you can do this question in a flash.
