Simple Explanation
Original density \(Population/Area\) है। नई density \(\frac{2Population}{Area/2}\) होगी, जो \(4 \times \frac{Population}{Area}\) के बराबर है। इसलिए density four times हो जाती है और तीसरा विकल्प सही है। यह question दिखाता है कि population increase और area decrease दोनों density को same direction में बढ़ाते हैं। परीक्षा में ratio carefully simplify करें। / Original density is \(Population/Area\). The new density is \(\frac{2Population}{Area/2}\), which equals \(4 \times \frac{Population}{Area}\). Therefore, density becomes four times the original value, making the third option correct. This question shows that increasing population and decreasing area both raise density in the same direction. In examinations, simplify the ratio carefully.
