यदि किसी region की arithmetic density 210 और habitable-area density 525 व्यक्ति प्रति वर्ग किलोमीटर है, तो habitable area total area का कितना प्रतिशत है?

B. 40 प्रतिशत40 percent
Simple Explanation
Arithmetic density \(P/A=210\) और habitable density \(P/H=525\) है। इसलिए \(H/A=210/525=0.4\)। Habitable area total area का 40 percent है। दूसरा विकल्प सही है। Remaining 60 percent area under the stated assumption settlement के लिए effectively unusable माना गया है। / Arithmetic density is \(P/A=210\), while habitable-area density is \(P/H=525\). Therefore, \(H/A=210/525=0.4\). Habitable area is 40 percent of total area, making the second option correct. Under the stated assumption, the remaining 60 percent is effectively unusable for settlement.
