Answer #1

A. Time required for reaching 10billion population:

Annual growth rate of 1.075% in 2019 (Given)

Population in 2020 7.6 billion

7.6billion(1+1.075%)^n = 10billions

(1.01075)^n = 10/7.6

=(1.01075)^n = 1.316

= n= 26 years i.e, In Year 2046 the population would be 10billions.

2. In case of males the population by then would be

7.6(1.01075)^57.1= 13.99bn

In case of females the population by then would be

7.6(1.01075)^61.8= 15.85bn
