Which city is more crowded? Why do you say so?To find which city is more crowded, we find Population Density And, Population density is defined as Population Density = 𝑃𝑜𝑝𝑢𝑙𝑎𝑡𝑖𝑜𝑛/𝐴𝑟𝑒𝑎 Thus, we find Population Density for both Delhi and Mumbai and find out which is more crowded Delhi Population = 30 million = 30,000,000 Area = 1,484 sq. km Population Density of Delhi = 30,000,000/1,484 ≈𝟐𝟎,𝟐𝟏𝟓 people per sq km Mumbai Population = 20 million = 20,000,000 Area = 550 sq. km Population Density of Mumbai = 20,000,000/550 ≈ 36,363 people per sq km
