pls answer with full steps and formulas

Answer 1

Answer:

Population in 2016=240000.

Step-by-step explanation:

Let the population of the town in 2016 was x.

Then, its population in 2017

=105% of x

=105/100 ×x

=21x/20.

Now, its population in 2018

=105% of 21x/20

=105/100 × 21x/20

=441x/400.

But, given population of town in 2018=264600.

Therefore, 441x/400=264600

=>x=264600×400/441

=>x=600×400

=>x=240000.

Hence, the population of the town in 2016 was 240000.
