Correct Answer
B. 10 प्रतिशत10 percent
Simple Explanation
New density multiplier \(\frac{1.54}{1.40}=1.10\) है। इसलिए density exactly 10 percent बढ़ती है और दूसरा विकल्प सही है। Population growth area growth से केवल relatively थोड़ा अधिक है, इसलिए density increase भी limited है। Combined percentage changes में direct subtraction 54 minus 40 equals 14 percent देना गलत होगा। / The new density multiplier is \(\frac{1.54}{1.40}=1.10\). Therefore, density increases by exactly 10 percent and the second option is correct. Population grows only modestly faster than area, so density rises by a limited amount. Directly subtracting 40 from 54 to obtain 14 percent would be incorrect for this ratio-based change.
