Understanding Percentage Increase
To calculate the percentage increase in a population, you need to follow a simple formula:
Percentage Increase = (New Value - Old Value) / Old Value * 100
This formula helps you determine how much the population has grown in relation to its original size.
Step-by-Step Calculation
1. Identify the Old and New Values
- Old Value (Initial Population) = 1,000
- New Value (Final Population) = 1,200
2. Calculate the Increase in Population
- Increase = New Value - Old Value
- Increase = 1,200 - 1,000 = 200
3. Use the Formula to Find the Percentage Increase
- Percentage Increase = (Increase / Old Value) * 100
- Percentage Increase = (200 / 1,000) * 100
4. Calculate the Result
- Percentage Increase = 0.2 * 100 = 20%
Conclusion
The percentage increase in the population from 1,000 to 1,200 is 20%. This means that the population has grown by one-fifth of its original size, which is a significant increase.
Thus, the correct answer is option 'A' - 20%.
