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.

15,972

 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 .
