यदि किसी city की gross density 420 है और land-only density 560 व्यक्ति प्रति वर्ग किलोमीटर है, तो water bodies total municipal area का कितना प्रतिशत हैं?

B. 25 प्रतिशत25 percent
Simple Explanation
Gross density \(P/A=420\) और land-only density \(P/L=560\) है। इसलिए \(L/A=420/560=0.75\)। Land total area का 75 percent है, इसलिए water bodies remaining 25 percent हैं। दूसरा विकल्प सही है। Density differences से area composition infer की जा सकती है जब numerator population same हो। / Gross density is \(P/A=420\), while land-only density is \(P/L=560\). Thus \(L/A=420/560=0.75\). Land occupies 75 percent of total area, so water bodies occupy the remaining 25 percent. Therefore, the second option is correct. When the same population is used as the numerator, density differences can reveal area composition.
