Question

The population of a town was 77000 in 2012. If it is increased by 25% every year after that, in which year did it cross 153000 for the first time ?

Answer 1

Answer:

Given that,

Population increases annually by 25%

Let population 3 years ago be x

⇒ Population two years ago was 

$= > \frac{125}{100} x$

Population last year was

$= > \frac{125 \times 125}{10000} x$

population this year is

$= > \frac{125 \times 125 \times 125}{1000000} x = 10000000$

⇒ Population three years ago was x=5120000

∴ Difference between population three years ago and two years ago =25% of x

=1280000
