यदि किसी region की density 40 प्रतिशत बढ़ती है जबकि population unchanged है, तो area original का कितना प्रतिशत रह जाएगा?

B. 71.4 प्रतिशत71.4 percent
Simple Explanation
Population constant और density multiplier 1.40 है। इसलिए area multiplier \(1/1.40=0.714285...\) है। अर्थात new area original का लगभग 71.4 percent है। दूसरा विकल्प सही है। Area लगभग 28.6 percent घटा। 40 percent density rise को 40 percent area decline मानना inverse relationship को गलत apply करना होगा। / Population is constant and the density multiplier is 1.40. Therefore, the area multiplier is \(1/1.40=0.714285...\). The new area is about 71.4 percent of the original. The second option is correct. Area decreased by about 28.6 percent. Treating a 40 percent density rise as a 40 percent area decline would misuse the inverse relationship.
