Question
The population of a city in the year 2020 was 2,00,000.
The rate of growth of population is 8% per annum. Find the population of that city in the year 2022.Solution
The population of a city in the year 2020 was 2,00,000. The rate of growth of population is 8% per annum. Population of that city in the year 2022 = 2,00,000 of (100+8)% of (100+8)% = 2,00,000 of 108% of 108% = 20x108x108 =Â 2,33,280
