Question 37
HardOriginal questionData for three countries:
| Country | Population (crore) | Area (lakh sq km) | Population growth (% a year) |
|---|---|---|---|
| X | 120 | 30 | 1.2 |
| Y | 140 | 96 | 0.4 |
| Z | 22 | 8 | 2.0 |
Using the data for the three countries, which country has the lowest population density?
Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
Density = population ÷ area: X = 120 ÷ 30 = 4 crore per lakh sq km (400 per sq km); Y = 140 ÷ 96 ≈ 1.46 (146); Z = 22 ÷ 8 = 2.75 (275).
Y has the most people but the most land, so its density is lowest.
Worth noting
Z has the fewest people, but it also has the least land.
