यदि population आधी हो और area double हो जाए, तो density क्या होगी?
If population becomes half and area doubles, what happens to density?

D. density original की एक-चौथाई होगीDensity will become one-fourth of the original
Simple Explanation
New density \(\frac{Population/2}{2Area}\) होगी, जो \(\frac{1}{4} \times \frac{Population}{Area}\) के बराबर है। इसलिए density original value की one-fourth हो जाती है और चौथा विकल्प सही है। Population decrease और area increase दोनों density को कम करते हैं। परीक्षा में numerator decrease और denominator increase के combined effect को ध्यान से समझें। / The new density is \(\frac{Population/2}{2Area}\), which equals \(\frac{1}{4} \times \frac{Population}{Area}\). Therefore, density becomes one-fourth of the original value and the fourth option is correct. A decrease in population and an increase in area both reduce density. In examinations, carefully consider the combined effect of a smaller numerator and a larger denominator.
