जनसंख्या घनत्व का सामान्य अर्थ क्या है?

What is the general meaning of population density?

Explanation opens after your attempt
Correct Answer

A. प्रति इकाई क्षेत्र में रहने वाले लोगों की संख्याNumber of people living per unit area

Explanation

Simple Explanation

जनसंख्या घनत्व किसी निश्चित क्षेत्रफल में रहने वाले लोगों की संख्या बताता है। सामान्यतः इसे कुल जनसंख्या को कुल क्षेत्रफल से विभाजित करके व्यक्त किया जाता है। इसलिए पहला विकल्प सही है। जन्म दर जनसंख्या परिवर्तन से संबंधित है लेकिन density नहीं बताती। इसी प्रकार वर्षा और केवल शहरी जनसंख्या भी population density की परिभाषा नहीं हैं। परीक्षा में density को लोगों की संख्या और land area के संबंध के रूप में याद रखें। / Population density expresses how many people live within a given unit of area. It is generally calculated by dividing total population by total land area. Therefore, the first option is correct. Birth rate is related to population change but does not define density. Rainfall and urban population alone also do not represent population density. For examinations, remember density as the relationship between the number of people and the area they occupy.

जनसंख्या घनत्व ज्ञात करने के लिए कौन-सा सूत्र सामान्यतः प्रयोग किया जाता है?

Which formula is generally used to calculate population density?

Explanation opens after your attempt
Correct Answer

B. \(Population\ Density = \frac{Population}{Area}\)

Explanation

Simple Explanation

जनसंख्या घनत्व निकालने के लिए कुल जनसंख्या को कुल क्षेत्रफल से विभाजित किया जाता है। इसलिए सही सूत्र \(Population\ Density = \frac{Population}{Area}\) है और दूसरा विकल्प सही है। पहले विकल्प में numerator और denominator उलटे हैं। गुणा या जोड़ करने से density प्राप्त नहीं होती। परीक्षा में population को ऊपर और area को नीचे रखकर formula याद करना उपयोगी है। / Population density is calculated by dividing the total population by the total area. Therefore, the correct formula is \(Population\ Density = \frac{Population}{Area}\), making the second option correct. The first option reverses the numerator and denominator, while multiplication or addition does not produce density. For examinations, remember that population goes in the numerator and area in the denominator.

जनसंख्या घनत्व की सामान्य इकाई क्या होती है?

What is a common unit of population density?

Explanation opens after your attempt
Correct Answer

C. व्यक्ति प्रति वर्ग किलोमीटरPersons per square kilometre

Explanation

Simple Explanation

जनसंख्या घनत्व किसी unit area में रहने वाले लोगों की संख्या दर्शाता है। इसलिए इसे सामान्यतः persons per square kilometre जैसी इकाई में व्यक्त किया जाता है और तीसरा विकल्प सही है। Kilometres per person दूरी जैसी इकाई है, जबकि people per year समय से संबंधित है। प्रतिशत भी सामान्य population density की इकाई नहीं है। परीक्षा में persons per square kilometre को standard expression के रूप में याद रखें। / Population density shows the number of people living in a unit of area. It is therefore commonly expressed as persons per square kilometre, making the third option correct. Kilometres per person is a distance-related expression, while people per year introduces a time dimension. Percentage is also not the normal unit of population density. In examinations, remember persons per square kilometre as the standard way of expressing density.

यदि किसी क्षेत्र की कुल जनसंख्या समान रहे लेकिन उसका क्षेत्रफल बढ़ जाए, तो population density पर क्या प्रभाव पड़ेगा?

If the total population of a region remains the same but its area increases, what happens to population density?

Explanation opens after your attempt
Correct Answer

D. यह सामान्यतः घटेगीIt will generally decrease

Explanation

Simple Explanation

जनसंख्या घनत्व में population numerator और area denominator होता है। यदि population समान रहे और area बढ़ जाए तो वही लोग बड़े क्षेत्र में फैले होंगे, इसलिए density कम हो जाती है। इस कारण चौथा विकल्प सही है। Density दोगुनी या zero होने की कोई आवश्यकता नहीं है और unchanged भी नहीं रहेगी। परीक्षा में denominator बढ़ने पर ratio घटने के सरल संबंध को समझें। / In population density, population is the numerator and area is the denominator. If population remains constant while area increases, the same number of people is spread over a larger area, so density decreases. Therefore, the fourth option is correct. Density does not necessarily double or become zero, and it cannot remain unchanged in this situation. In examinations, remember that increasing the denominator reduces the ratio when the numerator stays constant.

यदि population बढ़े और area समान रहे, तो जनसंख्या घनत्व में सामान्यतः क्या होगा?

If population increases while area remains the same, what generally happens to population density?

Explanation opens after your attempt
Correct Answer

A. जनसंख्या घनत्व बढ़ेगाPopulation density will increase

Explanation

Simple Explanation

Population density का सूत्र population को area से divide करता है। यदि area unchanged रहे और population बढ़े तो numerator बढ़ता है, इसलिए density भी बढ़ती है। इस कारण पहला विकल्प सही है। दूसरा विकल्प विपरीत संबंध बताता है और area अपने आप बदलना आवश्यक नहीं है। परीक्षा में समान area के भीतर अधिक लोगों का मतलब अधिक population density समझें। / Population density is calculated by dividing population by area. If the area remains unchanged while population increases, the numerator becomes larger and density also increases. Therefore, the first option is correct. The second option gives the opposite relationship, and the area does not automatically change. In examinations, remember that more people within the same area means a higher population density.

दो क्षेत्रों का क्षेत्रफल समान हो तो किस क्षेत्र की population density अधिक होगी?

If two regions have the same area, which region will have the higher population density?

Explanation opens after your attempt
Correct Answer

B. जिसकी population अधिक होThe one with the larger population

Explanation

Simple Explanation

जब दो क्षेत्रों का area समान हो तो population density का अंतर केवल population की संख्या से निर्धारित होगा। जिस क्षेत्र में अधिक लोग रहेंगे उसकी density अधिक होगी। इसलिए दूसरा विकल्प सही है। कम population वाले क्षेत्र की density कम होगी और rainfall इस calculation में सीधे शामिल नहीं है। परीक्षा में same-area comparison में larger population को higher density से जोड़ें। / When two regions have the same area, the difference in population density depends on their population totals. The region with more people will have the higher density. Therefore, the second option is correct. The region with fewer people will have a lower density, while rainfall does not directly enter this calculation. In examinations, for equal-area comparisons, associate a larger population with a higher density.

Explanation opens after your attempt
Correct Answer

C. जिसका area कम होThe one with the smaller area

Explanation

Simple Explanation

यदि population समान है तो smaller area में वही लोग अधिक compact रूप से बसे होंगे। Formula में area denominator है, इसलिए area कम होने पर density बढ़ती है। इस कारण तीसरा विकल्प सही है। Larger area वाले region में density lower होगी। Rainfall density की numerical calculation में सीधे शामिल नहीं होती। परीक्षा में equal-population comparison में smaller area को higher density से जोड़ें। / If population is the same, the same number of people is concentrated within a smaller area. Since area is the denominator in the density formula, a smaller area produces a higher density. Therefore, the third option is correct. A larger area gives a lower density. Rainfall does not directly enter the numerical calculation. In examinations, for equal-population comparisons, connect the smaller area with higher density.

किस स्थिति में population density सबसे कम होने की संभावना है?

Under which condition is population density most likely to be lowest?

Explanation opens after your attempt
Correct Answer

D. कम population और बहुत बड़ा areaSmall population and very large area

Explanation

Simple Explanation

Population density population और area के ratio पर निर्भर करती है। कम population यदि बहुत बड़े area में फैली हो तो persons per unit area कम होंगे, इसलिए density low होगी। इस कारण चौथा विकल्प सही है। बड़ी population और छोटा area सामान्यतः high density produce करता है। परीक्षा में low population plus large area को low density का सरल उदाहरण समझें। / Population density depends on the ratio between population and area. When a small population is spread over a very large area, the number of persons per unit area is low, so density is low. Therefore, the fourth option is correct. A large population within a small area generally creates high density. In examinations, remember small population plus large area as a simple pattern of low density.

Under which condition is population density most likely to be highest?

Explanation opens after your attempt
Correct Answer

A. बहुत बड़ी population और छोटा areaVery large population and small area

Explanation

Simple Explanation

High population density तब बनती है जब बड़ी संख्या में लोग comparatively छोटे area में रहते हैं। Formula में population अधिक और denominator area छोटा होने से ratio बड़ा मिलता है। इसलिए पहला विकल्प सही है। Small population with large area low density का उदाहरण है। परीक्षा में high density को large population concentration within limited space के रूप में समझें। / High population density occurs when a large number of people live within a comparatively small area. In the density formula, a larger population and a smaller area produce a larger ratio. Therefore, the first option is correct. A small population spread across a large area represents low density. In examinations, understand high density as a large concentration of people within limited space.

B. लोग किसी क्षेत्रफल में कितने सघन रूप से बसे हैंHow closely people are concentrated within an area

Explanation

Simple Explanation

Population density यह बताती है कि किसी निश्चित area में औसतन कितने लोग रहते हैं। इससे settlement concentration की सामान्य intensity समझी जा सकती है। इसलिए दूसरा विकल्प सही है। Density rainfall, birth rate या केवल urban population नहीं बताती। परीक्षा में density को people per unit area के माध्यम से spatial concentration का सामान्य माप समझें। / Population density tells us how many people, on average, live within a given unit of area. It therefore provides a general measure of how concentrated settlement is. The second option is correct. Density does not directly describe rainfall, birth rate, or only the urban population. In examinations, understand density as a general measure of spatial concentration expressed through people per unit area.

यदि किसी क्षेत्र की population 100000 और area 1000 वर्ग किलोमीटर हो, तो population density कितनी होगी?

If a region has a population of 100000 and an area of 1000 square kilometres, what is its population density?

Explanation opens after your attempt
Correct Answer

C. 100 व्यक्ति प्रति वर्ग किलोमीटर100 persons per square kilometre

Explanation

Simple Explanation

Population density के लिए \(Population\ Density = \frac{Population}{Area}\) प्रयोग करते हैं। यहां \(Population\ Density = \frac{100000}{1000} = 100\) persons per square kilometre मिलता है। इसलिए तीसरा विकल्प सही है। 10 और 50 बहुत कम values हैं जबकि 1000 तब मिलता यदि area केवल 100 square kilometres होता। परीक्षा में population को area से divide करना न भूलें। / Use \(Population\ Density = \frac{Population}{Area}\). Here \(Population\ Density = \frac{100000}{1000} = 100\) persons per square kilometre. Therefore, the third option is correct. Values of 10 and 50 are too small, while 1000 would result only with a much smaller area such as 100 square kilometres. In examinations, remember to divide population by area, not the reverse.

यदि population 50000 और area 500 वर्ग किलोमीटर हो, तो density कितनी होगी?

If population is 50000 and area is 500 square kilometres, what is the density?

Explanation opens after your attempt
Correct Answer

D. 100 व्यक्ति प्रति वर्ग किलोमीटर100 persons per square kilometre

Explanation

Simple Explanation

Formula \(Population\ Density = \frac{Population}{Area}\) के अनुसार \(Population\ Density = \frac{50000}{500} = 100\) persons per square kilometre है। इसलिए चौथा विकल्प सही है। यदि calculation में population और area को उल्टा कर दिया जाए तो गलत result मिलेगा। परीक्षा में zeros को simplify करके division करना आसान रहता है; 50000 को 500 से divide करने पर 100 मिलता है। / Using \(Population\ Density = \frac{Population}{Area}\), we get \(Population\ Density = \frac{50000}{500} = 100\) persons per square kilometre. Therefore, the fourth option is correct. Reversing population and area would give an incorrect result. In examinations, simplifying the zeros before division makes the calculation easier; dividing 50000 by 500 gives 100.

A. 40 व्यक्ति प्रति वर्ग किलोमीटर40 persons per square kilometre

Explanation

Simple Explanation

Population density निकालने के लिए \(Population\ Density = \frac{Population}{Area}\) प्रयोग करेंगे। यहां \(Population\ Density = \frac{24000}{600} = 40\) persons per square kilometre है। इसलिए पहला विकल्प सही है। 60, 80 और 120 इस division से प्राप्त नहीं होते। परीक्षा में units को final answer के साथ लिखना जरूरी है क्योंकि density केवल number नहीं बल्कि persons per unit area है। / To calculate population density, use \(Population\ Density = \frac{Population}{Area}\). Here \(Population\ Density = \frac{24000}{600} = 40\) persons per square kilometre. Therefore, the first option is correct. Values of 60, 80, and 120 do not result from this division. In examinations, always include the unit with the final answer because density is not just a number; it is persons per unit area.

Which area has a higher density: 20000 people in 100 square kilometres or 20000 people in 200 square kilometres?

Explanation opens after your attempt
Correct Answer

B. 100 वर्ग किलोमीटर वाला क्षेत्रThe 100 square kilometre area

Explanation

Simple Explanation

दोनों क्षेत्रों की population समान है, लेकिन पहले region का area छोटा है। पहले की density \(20000/100 = 200\) persons per square kilometre है, जबकि दूसरे की \(20000/200 = 100\) है। इसलिए 100 square kilometre वाला area अधिक dense है और दूसरा विकल्प सही है। परीक्षा में equal population होने पर smaller area को higher density से जोड़ें। / Both areas have the same population, but the first region has the smaller area. Its density is \(20000/100 = 200\) persons per square kilometre, while the second has \(20000/200 = 100\). Therefore, the 100 square kilometre region has the higher density, making the second option correct. In examinations, when population is equal, associate the smaller area with higher density.

Explanation opens after your attempt
Correct Answer

C. 60000 population वाला क्षेत्रThe area with population 60000

Explanation

Simple Explanation

दोनों regions का area 300 square kilometres है, इसलिए higher population वाला region higher density रखेगा। पहले की density \(30000/300 = 100\) और दूसरे की \(60000/300 = 200\) persons per square kilometre है। इसलिए तीसरा विकल्प सही है। परीक्षा में equal-area situations में population comparison से density आसानी से समझी जा सकती है। / Both regions have the same area of 300 square kilometres, so the region with the larger population has the higher density. The first density is \(30000/300 = 100\), while the second is \(60000/300 = 200\) persons per square kilometre. Therefore, the third option is correct. In examinations, equal-area situations allow density to be compared directly through population totals.

Explanation opens after your attempt
Correct Answer

C. density बढ़ेगीDensity will increase

Explanation

Simple Explanation

City area fixed होने पर additional residents same space में add होते हैं। Formula में population numerator बढ़ता है जबकि denominator unchanged रहता है, इसलिए population density बढ़ती है। तीसरा विकल्प सही है। Density decrease या unchanged तभी हो सकती है जब area या population का relation अलग हो। परीक्षा में fixed-area population growth को higher density से जोड़ें। / When the city area remains fixed, additional residents are added to the same space. In the formula, the population numerator increases while the denominator remains unchanged, so population density rises. Therefore, the third option is correct.

D. density भी आधी हो जाएगीDensity will also become half

Explanation

Simple Explanation

Population density सीधे population के proportional होती है जब area constant हो। यदि population आधी हो जाए और area same रहे, तो \(Population/Area\) ratio भी आधा हो जाएगा। इसलिए चौथा विकल्प सही है। Density double या unchanged नहीं रहेगी। परीक्षा में fixed area पर population के proportional change को density में समान proportional change से जोड़ें। / Population density is directly proportional to population when area is constant. If population falls by half and the area stays the same, the \(Population/Area\) ratio also becomes half. Therefore, the fourth option is correct. Density will not double or remain unchanged.

A. औसतन प्रत्येक वर्ग किलोमीटर में 150 लोग रहते हैंOn average 150 people live in each square kilometre

Explanation

Simple Explanation

Density 150 persons per square kilometre का अर्थ है कि total population और total area के ratio के अनुसार average रूप से प्रत्येक square kilometre पर 150 लोग आते हैं। इसका अर्थ यह नहीं कि region की total population केवल 150 है या area 150 है। इसलिए पहला विकल्प सही है। परीक्षा में density value को average concentration समझें, exact uniform distribution नहीं। / A density of 150 persons per square kilometre means that, according to the ratio of total population to total area, there are on average 150 people for each square kilometre. It does not mean that the total population is only 150 or that the region's area is 150 square kilometres. Therefore, the first option is correct. In examinations, interpret density as an average concentration, not an exactly uniform distribution.

क्या high population density का अर्थ यह है कि region का हर स्थान समान रूप से densely populated है?

Does high population density mean that every part of a region is equally densely populated?

Explanation opens after your attempt
Correct Answer

B. नहीं क्योंकि density पूरे region का average हो सकती हैNo because density may be an average for the whole region

Explanation

Simple Explanation

Arithmetic population density पूरे region की total population को total area से divide करती है, इसलिए यह average value है। एक ही region के कुछ parts densely settled और other parts sparsely settled हो सकते हैं। इसलिए दूसरा विकल्प सही है। High average density का अर्थ uniform local density नहीं है। परीक्षा में density और actual internal distribution के अंतर को समझना महत्वपूर्ण है। / Arithmetic population density divides the total population of a region by its total area, so it is an average value. Some parts of the same region may be densely settled while others are sparsely settled. Therefore, the second option is correct. A high average density does not mean uniform local density everywhere. In examinations, understand the difference between average density and actual internal distribution.

यदि किसी देश का अधिकांश population कुछ cities में concentrated हो और बाकी land sparsely populated हो, तो national density क्या दर्शाएगी?

If most of a country's population is concentrated in a few cities while the remaining land is sparsely populated, what will national density show?

Explanation opens after your attempt
Correct Answer

C. पूरे देश के population और area का average ratioThe average ratio of population to area for the whole country

Explanation

Simple Explanation

National population density total national population को total national area से divide करके average ratio देती है। यह individual cities or villages की exact local density नहीं बताती। इसलिए तीसरा विकल्प सही है। यदि population कुछ cities में concentrated हो तो national average internal contrasts को hide कर सकती है। परीक्षा में arithmetic density की यही limitation याद रखें। / National population density gives the average ratio obtained by dividing total national population by total national area. It does not show the exact local density of individual cities or villages. Therefore, the third option is correct. If population is concentrated in a few cities, the national average may hide strong internal contrasts. In examinations, remember this limitation of arithmetic density.

यदि किसी region की population 60000 से 90000 हो जाए और area समान रहे, तो density पर क्या effect होगा?

If a region's population rises from 60000 to 90000 while area remains unchanged, what effect will occur on density?

Explanation opens after your attempt
Correct Answer

D. density बढ़ेगीDensity will increase

Explanation

Simple Explanation

Area constant रहने पर population density population के साथ directly बढ़ती है। Population 60000 से 90000 होने पर numerator बढ़ा है जबकि denominator unchanged है, इसलिए density भी बढ़ेगी। चौथा विकल्प सही है। Exact new density निकालने के लिए area जानना होगा, लेकिन direction of change स्पष्ट है। परीक्षा में fixed-area population increase को higher density से जोड़ें। / When area remains constant, population density rises directly with population. As population increases from 60000 to 90000 while the denominator remains unchanged, density increases. Therefore, the fourth option is correct. The exact new density would require knowing the area, but the direction of change is clear. In examinations, connect population growth within a fixed area with increasing density.

यदि area double हो जाए लेकिन population unchanged रहे, तो density क्या होगी?

If area doubles while population remains unchanged, what happens to density?

Explanation opens after your attempt
Correct Answer

A. density आधी हो जाएगीDensity will become half

Explanation

Simple Explanation

Density \(Population/Area\) ratio है। यदि population same रहे और denominator यानी area double हो जाए तो ratio आधा हो जाता है। इसलिए पहला विकल्प सही है। Density double नहीं होगी क्योंकि population नहीं बढ़ी। परीक्षा में denominator के proportional change को समझना ratio-based questions हल करने में उपयोगी है। / Density is the \(Population/Area\) ratio. If population remains the same while the denominator, area, doubles, the ratio becomes half. Therefore, the first option is correct. Density does not double because population has not increased. In examinations, understanding proportional changes in the denominator helps solve ratio-based questions quickly.

यदि population और area दोनों double हो जाएं, तो density का क्या होगा?

If both population and area double, what happens to density?

Explanation opens after your attempt
Correct Answer

B. density समान रहेगीDensity will remain the same

Explanation

Simple Explanation

Original density \(Population/Area\) है। दोनों को double करने पर new ratio \(\frac{2Population}{2Area}\) होगा, जिसमें 2 cancel हो जाता है और original ratio ही बचता है। इसलिए density unchanged रहती है और दूसरा विकल्प सही है। परीक्षा में numerator और denominator समान proportion से बदलें तो ratio unchanged रहने का नियम याद रखें। / Original density is \(Population/Area\). If both are doubled, the new ratio becomes \(\frac{2Population}{2Area}\). The factor 2 cancels, leaving the original ratio unchanged. Therefore, density remains the same and the second option is correct. In examinations, remember that a ratio stays unchanged when both numerator and denominator change by the same proportion.

C. density चार गुना होगीDensity will become four times

Explanation

Simple Explanation

Original density \(Population/Area\) है। नई density \(\frac{2Population}{Area/2}\) होगी, जो \(4 \times \frac{Population}{Area}\) के बराबर है। इसलिए density four times हो जाती है और तीसरा विकल्प सही है। यह question दिखाता है कि population increase और area decrease दोनों density को same direction में बढ़ाते हैं। परीक्षा में ratio carefully simplify करें। / Original density is \(Population/Area\). The new density is \(\frac{2Population}{Area/2}\), which equals \(4 \times \frac{Population}{Area}\). Therefore, density becomes four times the original value, making the third option correct. This question shows that increasing population and decreasing area both raise density in the same direction. In examinations, simplify the ratio carefully.

D. density original की एक-चौथाई होगीDensity will become one-fourth of the original

Explanation

Simple Explanation

New density \(\frac{Population/2}{2Area}\) होगी, जो \(\frac{1}{4} \times \frac{Population}{Area}\) के बराबर है। इसलिए density original value की one-fourth हो जाती है और चौथा विकल्प सही है। Population decrease और area increase दोनों density को कम करते हैं। परीक्षा में numerator decrease और denominator increase के combined effect को ध्यान से समझें। / The new density is \(\frac{Population/2}{2Area}\), which equals \(\frac{1}{4} \times \frac{Population}{Area}\). Therefore, density becomes one-fourth of the original value and the fourth option is correct. A decrease in population and an increase in area both reduce density. In examinations, carefully consider the combined effect of a smaller numerator and a larger denominator.

A. ऐसा thematic map जिसमें regions को density values के अनुसार दिखाया जाएA thematic map showing regions according to density values

Explanation

Simple Explanation

Population density spatial data है, इसलिए thematic maps regions की density values को compare करने में उपयोगी होते हैं। अलग-अलग areas को density classes के अनुसार दिखाने से high और low density patterns समझे जा सकते हैं। इसलिए पहला विकल्प सही है। Road or weather maps का primary purpose density दिखाना नहीं है। परीक्षा में thematic mapping को population geography data visualization से जोड़ें। / Population density is spatial data, so thematic maps are useful for comparing density values among regions. Areas can be shown according to density classes, making high- and low-density patterns easier to understand. Therefore, the first option is correct.

C. प्रति इकाई area में comparatively अधिक लोग रहते हैंComparatively more people live per unit area

Explanation

Simple Explanation

High population density का direct meaning यही है कि persons per unit area comparatively अधिक हैं। यह जरूरी नहीं कि area छोटा ही हो या सभी लोग cities में रहते हों, क्योंकि density population और area दोनों के ratio से बनती है। इसलिए तीसरा विकल्प सही है। परीक्षा में high density को numerical concentration समझें, न कि automatically urbanization का synonym। / High population density directly means that comparatively more people live per unit area. It does not necessarily mean that the area is small or that everyone lives in a city, because density depends on the ratio of population to area. Therefore, the third option is correct.

Correct Answer

A. 40000 population और 200 area वाला regionThe region with population 40000 and area 200

Explanation

Simple Explanation

पहले region की density \(40000/200 = 200\) persons per square kilometre है। दूसरे की density \(50000/500 = 100\) persons per square kilometre है। इसलिए पहला region अधिक dense है और पहला विकल्प सही है। केवल total population देखकर comparison नहीं करना चाहिए क्योंकि area भी density को प्रभावित करता है। परीक्षा में दोनों ratios calculate करके compare करें। / The first region has a density of \(40000/200 = 200\) persons per square kilometre. The second has \(50000/500 = 100\) persons per square kilometre. Therefore, the first region has the higher density, making the first option correct.

Explanation opens after your attempt
Correct Answer

B. 150 density वाला regionThe region with density 150

Explanation

Simple Explanation

Population density values already persons per unit area का comparison देती हैं। 150 persons per square kilometre, 75 से अधिक है, इसलिए second region more dense है। दूसरा विकल्प सही है। Area separately जानने की आवश्यकता नहीं है क्योंकि density calculation पहले ही population और area दोनों को include करती है। परीक्षा में given density values को directly compare किया जा सकता है। / Population-density values already provide a comparison in persons per unit area. A value of 150 persons per square kilometre is greater than 75, so the second region is denser. Therefore, the second option is correct. There is no need to know area separately because density already incorporates both population and area. In examinations, given density values can be compared directly.
