Correct Answer
C. 120 प्रतिशत120 percent
Simple Explanation
Population \(=Density\times Area\)। इसलिए population multiplier \(1.25\times0.96=1.20\) है। Population original की 120 percent होगी, अर्थात 20 percent increase। इसलिए तीसरा विकल्प सही है। Density increase और area decrease दोनों को combine करना जरूरी है; केवल density change देखकर population change नहीं निकाला जा सकता। / Population equals density multiplied by area. Therefore, the population multiplier is \(1.25\times0.96=1.20\). Population becomes 120 percent of the original, an increase of 20 percent. The third option is correct. Both density and area changes must be combined; population change cannot be inferred from density alone.
