Simple Explanation
क्योंकि \(Density = Population/Area\), इसलिए \(Area = Population/Density\)। Area ratio होगा \(\frac{9}{3}:\frac{4}{2} = 3:2\)। इसलिए दूसरा विकल्प सही है। केवल population ratio 9:4 को area ratio मानना गलत होगा, क्योंकि density differences भी account करने होते हैं। परीक्षा में area ratio निकालने के लिए population ratio को density ratio से divide करें। / Since \(Density = Population/Area\), area equals population divided by density. The area ratio is therefore \(\frac{9}{3}:\frac{4}{2} = 3:2\). Hence the second option is correct. Using the population ratio 9:4 directly as the area ratio would be wrong because density differences must also be considered. To obtain area ratio, divide the population ratio by the density ratio.
