Question 12 of 22intermediate🔍 AnalyzeLong Answer3 marks

The area of Delhi is 1,484 sq. km and the area of Mumbai is 550 sq. km. The population of Delhi is approximately 30 million and that of Mumbai is 20 million people. Which city is more crowded? Why do you say so?

Correct Answer

Mumbai is more crowded than Delhi.

Population density of Delhi: 30,000,000 ÷ 1,484 ≈\approx 20,216 people per sq. km

Population density of Mumbai: 20,000,000 ÷ 550 ≈\approx 36,364 people per sq. km

Comparison: 36,364 > 20,216

Why: Since Mumbai has a higher population density (more people per square kilometre), it is more crowded.

Explanation

To determine which city is more crowded, we need to compare population density (people per unit area). The city with higher population density is more crowded.

Solution Steps

  1. Step 1: Calculate population density of Delhi = 30,000,000 ÷ 1,484 ≈\approx 20,216 people/sq.km

  2. Step 2: Calculate population density of Mumbai = 20,000,000 ÷ 550 ≈\approx 36,364 people/sq.km

  3. Step 3: Compare: 36,364 > 20,216

  4. Step 4: Mumbai has higher population density, so it is more crowded
