Which mathematical idea is involved in linking India's area with population density?

Answer and explanation

Correct answer: जनसंख्या को क्षेत्रफल पर विभाजित करना (Dividing population by area)

The governing mathematical idea is a ratio: population density expresses the average number of people living per unit of land area. The basic calculation is population density = total population ÷ area, usually reported as persons per square kilometre. For example, if a region has 2,000,000 people and covers 10,000 km², its average density is 200 persons per km². Thus option A is correct. The measure does not add coastline to longitude, multiply time by latitude or convert a land boundary into a percentage. Density is an average and may hide local differences, but its essential calculation always requires population divided by area.
