3,00,000
Incorrect Answer2,10,000
Incorrect Answer1,20,000
Incorrect AnswerExplanation:
- The town's population is growing at 10% per year.
- Currently, the population is 1,00,000.
- To find the population after 2 years, we use the formula: Future Population = Present Population × (1 + Growth Rate)^Number of Years.
- Calculation:
- After 1 year: 1,00,000 × 1.10 = 1,10,000
- After 2 years: 1,10,000 × 1.10 = 1,21,000
- Option 1: 3,00,000 - This is too high for a 10% growth over 2 years.
- Option 2: 1,21,000 - This is the correct population after 2 years.
- Option 3: 2,10,000 - Also too high.
- Option 4: 1,20,000 - Slightly less than the correct calculation.
