Problem-Solving and Data Analysis practice question
A company with 250 employees laid off 20% of them. It later rehired 10% of the employees it had laid off. How many employees does the company have now?
Answer: 205
Laid off: 0.20 × 250 = 50, leaving 200. Rehired: 10% of the 50 laid off = 5. Now: 200 + 5 = 205.
Common wrong answers
- If you answered 200
- 200 forgets the rehired employees.
- If you answered 220
- 220 takes 10% of the remaining 200 instead of 10% of the 50 laid off.
- If you answered 225
- 225 treats the 10% as applying to the whole company (25 people), but it applies to the 50 laid off.
