Simple Explanation
relative density factor population share divided by area share होता है। यहाँ \(\frac{0.30}{0.10}=3\)। इसलिए selected area का density region average का तीन गुना होगा और विकल्प B सही है। इस calculation के लिए actual population या area जानना आवश्यक नहीं है। परीक्षा में share-based density questions के लिए population percentage को area percentage से divide करें। / Relative density factor equals population share divided by area share. Here \(\frac{0.30}{0.10}=3\). Therefore the selected area has three times the average density of the whole region and option B is correct. Actual population and area values are not required. In examinations divide the population percentage by the area percentage for share-based density questions.
