यदि density 480 से बढ़कर 600 व्यक्ति प्रति वर्ग किलोमीटर हो और area 15 प्रतिशत बढ़े, तो population कितने प्रतिशत बढ़ी?

Correct Answer
C. 43.75 प्रतिशत43.75 percent
Simple Explanation
Density multiplier \(600/480=1.25\) है और area multiplier 1.15 है। इसलिए population multiplier \(1.25\times1.15=1.4375\) होगा। Population 43.75 percent बढ़ी और तीसरा विकल्प सही है। केवल density rise 25 percent को population growth मानना गलत होगा क्योंकि area भी बढ़ी है। / The density multiplier is \(600/480=1.25\), while the area multiplier is 1.15. Therefore, the population multiplier is \(1.25\times1.15=1.4375\). Population increased by 43.75 percent, so the third option is correct. It would be wrong to treat the 25 percent density rise as the population increase because area also expanded.
