Correct Answer
C. 108 प्रतिशत108 percent
Simple Explanation
Population multiplier \(0.90 \times 1.20 = 1.08\) है। इसलिए population original की 108 percent होगी, अर्थात 8 percent increase। तीसरा विकल्प सही है। Density decline के बावजूद total population बढ़ सकती है यदि area sufficiently expand करे। यह density और total population के difference को दर्शाता है। / The population multiplier is \(0.90 \times 1.20 = 1.08\). Therefore, population becomes 108 percent of the original, an increase of 8 percent. The third option is correct. Total population can rise even when density falls if area expands sufficiently. This illustrates the difference between density and total population.
