Answer 2

The population was 153846 of a year ago

Step-by-step explanation:

Let the initial population be x

We are given that the population of a town increases by 4% every year

So, Population after 1 year = $x+4\%x=x+0.04x=1.04x$

We are given that ts current population is 1.6 lakh i.e. 160000

So, $1.04x=160000\\x=\frac{160000}{1.04}\\x=153846.15$

Hence The population was 153846 of a year ago
