यदि population 50000 और area 500 वर्ग किलोमीटर हो, तो density कितनी होगी?
If population is 50000 and area is 500 square kilometres, what is the density?
Explanation opens after your attempt
D. 100 व्यक्ति प्रति वर्ग किलोमीटर100 persons per square kilometre
Simple Explanation
Formula \(Population\ Density = \frac{Population}{Area}\) के अनुसार \(Population\ Density = \frac{50000}{500} = 100\) persons per square kilometre है। इसलिए चौथा विकल्प सही है। यदि calculation में population और area को उल्टा कर दिया जाए तो गलत result मिलेगा। परीक्षा में zeros को simplify करके division करना आसान रहता है; 50000 को 500 से divide करने पर 100 मिलता है। / Using \(Population\ Density = \frac{Population}{Area}\), we get \(Population\ Density = \frac{50000}{500} = 100\) persons per square kilometre. Therefore, the fourth option is correct. Reversing population and area would give an incorrect result. In examinations, simplifying the zeros before division makes the calculation easier; dividing 50000 by 500 gives 100.
