Question

The population of a village was 130000. It increased by 10% in the first year and increased by 25% in the second year. Its population after two years is _______.

• A. 178750
• B. 175500
• C. 162500
• D. 143000

Answer 1

Answer:

A. 178750

1. Calculate the population increase in the first year:

• Initial population = 130000

• Increase percentage = 10%

• Increase in population = 10% of 130000 = (10/100) * 130000 = 13000

2. Calculate the population after the first year:

• Population after first year = Initial population + Increase in population

• Population after first year = 130000 + 13000 = 143000

3. Calculate the population increase in the second year:

• Population at the beginning of the second year = 143000

• Increase percentage = 25%

• Increase in population = 25% of 143000 = (25/100) * 143000 = 35750

4. Calculate the population after the second year:

• Population after second year = Population after first year + Increase in population

• Population after second year = 143000 + 35750 = 178750

Therefore, the population after two years is 178750.
