The population of a village has a constant growth of 5% every year. if its present population is 1,04,832, what was the population two years ago?

95086

Step-by-step explanation:

We let the population one year ago be x, the relationship between x and the present population is;

(105/100)*x = 104832

This is because the present population exceeds the population one year ago by 5%.

therefore,

1.05*x =  104832

x = 99840

We now let the population two years ago be y, the relationship between y and the population one year ago is;

(105/100)*y = 99840

This is because the population one year ago exceeds the population two years ago by 5%.

Therefore,

1.05*y = 99840

y = 95085.7

Rounding to the nearest whole number;

95086
