Question

Present population of a village is 46080. What is the population of the village 2 years

ago if the rate of increase in the population was 20% every year​

Answer 1

Answer:

Step-by-step explanation:

Let the population before two years ago be x

Given the population increases by 10%

So increase in population after one year is  

100

10

​  

×x=0.1x

So population after one year is x+0.1x=1.1x

Increase in population after another one year is  

100

10

​  

×1.1x=0.11x

So population at present is 1.1x+0.11x=1.21x

But given population at present is 3,02,500

⟹1.21x=302500

⟹x=  

1.21

302500

​  

=2,50,000

Population of city two years ago is 2,50,000
