A town's population was 800 in 2015 and 1000 in 2020. By what percentage did the population change between the two years?
Answer and explanation
Correct answer: C. 25% increase
- Step 1: Change = 200.
- Step 2: Percentage change = 200 ÷ 800 × 100 = 25%, so the population increased.
Answer
25% increase.
Why not the others: 200 people: this is the number difference, not the percentage. 20% increase: the change was divided by the later year instead of the earlier year. 35% increase does not fit.
