यदि किसी region की population आधी हो जाए और area समान रहे, तो density का क्या होगा?
If a region's population becomes half while area remains unchanged, what happens to its density?

D. density भी आधी हो जाएगीDensity will also become half
Simple Explanation
Population density सीधे population के proportional होती है जब area constant हो। यदि population आधी हो जाए और area same रहे, तो \(Population/Area\) ratio भी आधा हो जाएगा। इसलिए चौथा विकल्प सही है। Density double या unchanged नहीं रहेगी। परीक्षा में fixed area पर population के proportional change को density में समान proportional change से जोड़ें। / Population density is directly proportional to population when area is constant. If population falls by half and the area stays the same, the \(Population/Area\) ratio also becomes half. Therefore, the fourth option is correct. Density will not double or remain unchanged. In examinations, remember that with fixed area, proportional changes in population produce the same proportional changes in density.
