यदि किसी city का area 400 से बढ़कर 500 वर्ग किलोमीटर हो जाए और population 240000 same रहे, तो new density क्या होगी?
Explanation opens after your attempt
B. 480 व्यक्ति प्रति वर्ग किलोमीटर480 persons per square kilometre
Simple Explanation
New density \(240000/500 = 480\) persons per square kilometre है। इसलिए दूसरा विकल्प सही है। Original density \(240000/400 = 600\) थी, इसलिए boundary expansion के बाद calculated density घटती है। यह example दिखाता है कि administrative area change statistical density को बदल सकता है, भले actual residents न बदलें। / The new density is \(240000/500 = 480\) persons per square kilometre. Therefore, the second option is correct. The original density was \(240000/400 = 600\), so calculated density falls after boundary expansion. This example shows that administrative-area changes can alter statistical density even when the number of residents remains unchanged.
