यदि population और area दोनों double हो जाएं, तो density का क्या होगा?
If both population and area double, what happens to density?
Explanation opens after your attempt
B. density समान रहेगीDensity will remain the same
Simple Explanation
Original density \(Population/Area\) है। दोनों को double करने पर new ratio \(\frac{2Population}{2Area}\) होगा, जिसमें 2 cancel हो जाता है और original ratio ही बचता है। इसलिए density unchanged रहती है और दूसरा विकल्प सही है। परीक्षा में numerator और denominator समान proportion से बदलें तो ratio unchanged रहने का नियम याद रखें। / Original density is \(Population/Area\). If both are doubled, the new ratio becomes \(\frac{2Population}{2Area}\). The factor 2 cancels, leaving the original ratio unchanged. Therefore, density remains the same and the second option is correct. In examinations, remember that a ratio stays unchanged when both numerator and denominator change by the same proportion.
