If Region A has population of thirty lakh and area of five thousand square kilometres while Region B has population of twelve lakh and area of twelve hundred square kilometres, which has higher density?

Answer and explanation

Correct answer: Region B

Correct answer: B, Region B. Population density means the average number of people living in one square kilometre. Use the formula: density = population ÷ area. Region A has 30 lakh people over 5,000 square kilometres, so its density is 300,0000? Written in lakh units, 30,00,000 ÷ 5,000 = 600 persons per square kilometre. Region B has 12,00,000 ÷ 1,200 = 1,000 persons per square kilometre. Thus B has the higher density even though its total population is smaller. Option A is wrong because it compares population without considering area. C is wrong because 600 and 1,000 are not equal. D is wrong because both regions have positive populations. Memory cue: density is a ratio, so always divide population by area before comparing.
