Answers
Answer:
Step-by-step explanation:
Let the population of the town after 2 years be x
Increase percent of population every year = 10%
Present population = 180000
= 10% of 180000
= 10/100 * 180000 = 10*1800 = 18000
Increase in population after 1 year = 180000+18000 = 198000
Increase in population afer 2 years = 10% of population in 1 year + population of 1 year
= 10% of 198000+198000
= 10/100 * 198000 = 10*1980 = 19800
= 198000+19800 = 217800
Therefore, the population of the town after 2 years is 2,17,800.
Increase population per year = 15%
present population = 1,20,000
Total population After two years = ?
= 15 × 120000 × 2/100
= 15 × 2 × 1200
= 30 × 1200
= 36000
Total population After two years = 36000 + 120000 = 1,56,000
