If an area has population of one lakh and area of five hundred square kilometres, what will be the density?

Answer and explanation

Correct answer: Two hundred persons per square kilometre

Population density = total population ÷ total area. Here, one lakh = 100,000 persons, so 100,000 ÷ 500 = 200 persons per square kilometre. Therefore, option A is correct. A density of 500 persons per square kilometre would require a population of 250,000 over this area. Exam tip: first convert lakh into a number, then divide population by area and write the unit.
