Problem-Solving and Data Analysis practice question
After a 15% raise, an employee's salary is $41,400. What was the salary before the raise, in dollars?
Answer: 36000
1.15 × original = 41,400 → original = 41,400 ÷ 1.15 = 36,000.
Common wrong answers
- If you answered 6210
- 6,210 is 15% of 41,400, not the original salary.
- If you answered 35190
- 35,190 subtracts 15% of the new salary instead of dividing by 1.15.
- If you answered 47610
- 47,610 adds 15% again.
