Simple Explanation
selected area का relative density factor \(\frac{0.70}{0.35}=2\) है। national average 220 है इसलिए selected area density \(220\times2=440\) व्यक्ति प्रति वर्ग किलोमीटर होगा। इसलिए विकल्प C सही है। 400 population और area shares के exact ratio को ignore करता है। परीक्षा में subregional density निकालने के लिए national density को population share divided by area share से multiply करें। / The relative density factor of the selected area is \(\frac{0.70}{0.35}=2\). National average density is 220, so density of the selected area is \(220\times2=440\) persons per square kilometre. Therefore option C is correct. A value of 400 ignores the exact relationship between population and area shares. Multiply national density by population share divided by area share.
