If the population of a town is 12,000 and the population increases at the rate of 10% per annum, then find the population after 3 years.
Answer & explanation
Correct answer: option 1
Present population = 12000
According to question ,
Population after 3 years = 12000 × \(\frac{100+10}{100}\) × \(\frac{100+10}{100}\) × \(\frac{100+10}{100}\)
= 12000 × \(\frac{110}{100}\) × \(\frac{110}{100}\) × \(\frac{110}{100}\)
= 15972
So , Population after 3 years is 15972 .
