Explanation / Answer

Given 4 countries birthrate and deathrates

Here, need to find the Net growth rate of country C for each year.

For year 1985:

Given Birthrate/1000=10.2

Deathrate/1000=11.5

Net growth rate can be obtained by subtracting deathrate from birthrate.

Net growthrate= Bithrate-Deathrate

=10.2 - 11.5

= -1.3

Here '-' sign shows that there is no growth of population.The population is declining.

For year 1995:

Given birthrate=11.2

deathrate=10.9

Net growthrate= 11.2-10.9

= 0.3

In this year, there is a growth of 0.3

For year 2003:

Given Birthrate=12.3

Deathrate= 10.4

Net growthrate=12.3-10.4

= 1.9

There is much growth in the year 2003 which is 1.9

By observing the growth rates for the 3 years, the net growthrate is increasing i.e., The population is increasing.

Therefore, After next 20 years, the The country's population will increase.

Therefore, Net growth rate for 1985 is -1.3

Net growth arte for 1995 is 0.3

Net growth rate for 2003 is 1.9

And Best prediction for Country C future population is "The Country's population will increase"

Option C is the correct one.
