Given ;
• Present population of town = 21,250
• Rate of increase in population annually = 15%

=> Let the population 1 year ago be x .

Now,

=> Present Population = X ( 1 + 15/100 ) 1

=> 21250 = X x 115/100

=> X = 21250*100/115

=> 18478 { Approximate }

Hence , the population 1 year ago will be 18478 .

Answer 2

Solutions :-

Given :
The present population of a town = 21250
The population of a town increased every year = 15%

Let the population of a year be x


According to the question,

=> x + 15% of x = 21250
=> x + 0.15x = 21250
=> 1.15x = 21250
=> x = 21250/1.15 = 18478 (approx)


Hence,
The population of a year = 18478
