Simple Explanation
Population density के लिए \(Population\ Density = \frac{Population}{Area}\) प्रयोग करते हैं। यहां \(Population\ Density = \frac{100000}{1000} = 100\) persons per square kilometre मिलता है। इसलिए तीसरा विकल्प सही है। 10 और 50 बहुत कम values हैं जबकि 1000 तब मिलता यदि area केवल 100 square kilometres होता। परीक्षा में population को area से divide करना न भूलें। / Use \(Population\ Density = \frac{Population}{Area}\). Here \(Population\ Density = \frac{100000}{1000} = 100\) persons per square kilometre. Therefore, the third option is correct. Values of 10 and 50 are too small, while 1000 would result only with a much smaller area such as 100 square kilometres. In examinations, remember to divide population by area, not the reverse.
