Answer:
It is given that
Present population = 6760000
Increase percent = 4% p.a.
(i) We know that
Population 2 years hence = P(1+r/100)n
Substituting the values
= 6760000(1+4/100)2
By further calculation
=6760000×26/25×26/25
=7311616
(ii) We know that A = 6760000
Population 2 years ago P=A+(1+r/100)2
Substituting the values
= 6760000+(1+4/100)2
By further calculation
= 6760000+(26/25)2
=6760000×25/26×25/26
= 6250000
