Answer 1

⚡Hey mate⚡

✨Here is your answer✨

Population in 1981 = 4.54 lakhs

In 2001 it was = 7.44 lakhs


It means that year of increasing is = 2001 - 1981

= 20 years

Increased population is = 2001 population - 1981 population

Increased population = 7.44 - 4.54

Increased population = 2.9 lakhs


It means that in 20 years population were increased 2.9 lakhs then only one year increasing is

20 years = 2.9

1 year = 2.9 ÷ 20

1 year = 0.145 lakes

We have to Calculate the estimated mid-year population of that district in year 2009.

Difference between 2009 and 2001 (2009 - 2201 = 8 ) is eight years.

If in 1 year increase 0.145 lakhs then 8 years increasing is ??????

1 year = 0.145 lakhs

8 years = 0.145 × 8

8 years = 1.16 lakhs


2009 total population is = 2001 population + 8 years increased population

2009 population =7.44 + 1.16

2009 population = 8.6 lakes



I hope it's helpful for you. Thank you ❤️❤️
