यदि किसी region की area boundary 1000 से बढ़कर 1250 वर्ग किलोमीटर हो जाए और population 200000 ही रहे, तो density कितनी होगी?
Explanation opens after your attempt
B. 160 व्यक्ति प्रति वर्ग किलोमीटर160 persons per square kilometre
Simple Explanation
New area 1250 square kilometres और population 200000 है। इसलिए \(Population\ Density = \frac{200000}{1250} = 160\) persons per square kilometre। दूसरा विकल्प सही है। Original density 200 थी, इसलिए boundary expansion के बाद density decrease होना expected है। परीक्षा में administrative area changes calculated density को बदल सकते हैं even when population unchanged हो। / The new area is 1250 square kilometres while population remains 200000. Therefore, \(Population\ Density = \frac{200000}{1250} = 160\) persons per square kilometre. The second option is correct. The original density was 200, so a decline after boundary expansion is expected. In examinations, remember that administrative-area changes can alter calculated density even when population remains unchanged.
