Question 1/2 Expert Geography The World Population – Distribution, Density and Growth Population Density Class 12 Level 21

यदि density unchanged है और population 240000 से 324000 हो जाती है, तो area में कितने प्रतिशत वृद्धि हुई?

If density remains unchanged while population rises from 240000 to 324000, by what percentage did area increase?

Correct Answer

C. 35 प्रतिशत35 percent

Explanation

Simple Explanation

Population increase \(324000-240000=84000\) है। Percentage increase \(\frac{84000}{240000}\times100=35\%\) है। Density unchanged होने के लिए area को भी exactly 35 percent बढ़ना होगा। इसलिए तीसरा विकल्प सही है। Constant density का अर्थ population and area का same proportional change है। / Population increases by \(324000-240000=84000\). Percentage increase is \(\frac{84000}{240000}\times100=35\%\). For density to remain unchanged, area must also increase by exactly 35 percent. Therefore, the third option is correct. Constant density means population and area change by the same proportion.

Question 2/2 Expert Geography The World Population – Distribution, Density and Growth Population Density Class 12 Level 19

यदि किसी city की resident density 1000 है और daytime density 1350 व्यक्ति प्रति वर्ग किलोमीटर है, तो daytime density resident density से कितने प्रतिशत अधिक है?

If a city's resident density is 1000 and daytime density is 1350 persons per square kilometre, by what percentage is daytime density higher?

Correct Answer

C. 35 प्रतिशत35 percent

Explanation

Simple Explanation

Difference \(1350-1000=350\) है। Percentage increase resident density के relative \(\frac{350}{1000}\times100=35\%\) है। इसलिए तीसरा विकल्प सही है। 350 absolute difference है, percentage नहीं। परीक्षा में comparison का base resident density है क्योंकि पूछा गया है daytime density उससे कितने percent अधिक है। / The difference is \(1350-1000=350\). Percentage increase relative to resident density is \(\frac{350}{1000}\times100=35\%\). Therefore, the third option is correct. The value 350 is the absolute difference, not the percentage. The comparison base is resident density because the question asks how much higher daytime density is relative to it.
