Simple Explanation
यदि total administrative area calculation में lake area भी include हो और population unchanged रहे, तो denominator बढ़ेगा। इसलिए arithmetic density घटेगी। दूसरा विकल्प सही है। यह example बताता है कि density boundary and area-definition sensitive measure है। परीक्षा में different cities की density compare करते समय area definitions comparable होना जरूरी है। / If the lake area is included in total administrative area while population remains unchanged, the denominator increases. Therefore, arithmetic density decreases. The second option is correct. This example shows that density is sensitive to boundary and area definitions. In examinations, area definitions should be comparable when comparing densities of different cities.
