If the population is 8000 and 75% attended, how many did not attend?

Correct answer: 2000. 25% did not attend: 25% of 8000 = 2000.

Background: Did not attend = 100% − 75% = 25%.

• 1500: 1500 is not 25% of 8000.
• 1800: 1800 is not 25% of 8000.
• 2500: 2500 is not 25% of 8000.

Did you know? 75% of 8000 is 6000, and 8000 − 6000 = 2000.

Memory trick: 100% − 75% = 25%.
