Question

15. The population of a town increases at the rate
of 5% every year. The present population is
8000. When will it become 9261?​

Answer 1

Step-by-step explanation:

Present population = 9261

Let the population 3 years ago = x

9261=x×[(100×5100+100)×1100]3

9261=x×105100×105100×105100

x=9261×20×20×2021×21×21=Rs.8000
