Answer:

It is given that

Birth rate = 9.2%

Death rate = 1.7%

So the net growth rate = 9.2 - 1.7 = 7.5%

Present population (P) = 320000

Period (N) = 3 years

We know that

Population after 3 years (A) = P(1+r/100)

n

Substituting the values

=320000(1+7.5/100)

3

By further calculation

=320000(1+3/40)

3

=320000×(43/40)

3

So we get

= 320000×43/40×43/30×43/40

=397535
