Simple Explanation
Formula \(Population\ Density = \frac{Population}{Area}\) के अनुसार \(Population\ Density = \frac{120000}{600} = 200\) persons per square kilometre है। इसलिए चौथा विकल्प सही है। अन्य options division के सही result नहीं हैं। परीक्षा में zeros simplify करने पर 120000 divided by 600 को 1200 divided by 6 की तरह देखकर 200 आसानी से निकाला जा सकता है। / Using \(Population\ Density = \frac{Population}{Area}\), we get \(Population\ Density = \frac{120000}{600} = 200\) persons per square kilometre. Therefore, the fourth option is correct. The other options do not match the correct division. In examinations, simplifying zeros can make the calculation easier because 120000 divided by 600 reduces to 1200 divided by 6, which equals 200.
