यदि किसी region के 25 प्रतिशत area में 50 प्रतिशत population रहती है और बाकी population शेष area में, तो dense portion की density बाकी portion से कितनी गुना होगी?
Explanation opens after your attempt
B. 3 गुना3 times
Simple Explanation
First portion की relative density \(0.50/0.25 = 2\) times regional average है। Remaining portion में 50 percent population 75 percent area में रहती है, इसलिए relative density \(0.50/0.75 = 2/3\) है। Ratio \(2 \div (2/3)=3\) है। इसलिए पहला portion बाकी portion से 3 times dense है और दूसरा विकल्प सही है। / The first portion has relative density \(0.50/0.25 = 2\) times the regional average. The remaining portion contains 50 percent of the population in 75 percent of the area, giving relative density \(0.50/0.75 = 2/3\). Their ratio is \(2 \div (2/3)=3\). Therefore, the first portion is three times denser than the remainder, making the second option correct.
