Which of the following is NOT correct in respect of density of world population?

If area of Region X is 100 sq km and the population is 1,50,000 persons. The density of population will be 150 person/sq km

The correct answer is Option 3: If area of Region X is 100 sq km and the population is 1,50,000 persons. The density of population will be 150 person/sq km

Each unit of land has limited capacity to support people living on it. Hence, it is necessary to understand the ratio between the numbers of people to the size of land. This ratio is the density of population. It is usually measured in persons per sq km.

Density of Population = Population/Area

An area of Region X is 100 sq km and the population is 1,50,000 persons. The density of population is calculated as: Density = 1,50,000/ 100 = 1,500 person/sq km
