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
