Question

the population of a town increased by 10.5% every year. if it's present population is 7,95,600, what was it a year ago ?

Answer 1

Present population = 795600

Percentage increases every year = 10.5 %

Therefore 10.5 % of present population = 795600 * 105/ 1000

                                                                  = 83538

Therefore last years population = 795600 - 83538

                                                        = 712062

I pray it help you
