QUESTION 1 OF 20

Consider the following statements about assessing population change over time: The annual growth rate of India's population is calculated using only the inward and outward movement of people. Population growth can be expressed in both absolute numbers and percentage rates. Which of the statements is/are true?

List-I	List-II
1. Absolute Number Growth	a. Calculated as \(\frac{\left(P_{2}\ −\ P_{1}\right)}{P_{1}}\times 100\)
2. Decadal Growth Rate (%)	b. The raw difference between the population of the present year and the base year
3. Positive Population Growth	c. Population of the later period is greater than the base period
4. Negative Population Growth	d. Population of the later period is lower than the base period

Answer Review

1 Consider the following statements about assessing population change over time: The annual growth rate of India's population is calculated using only the inward and outward movement of people. Population growth can be expressed in both absolute numbers and percentage rates. Which of the statements is/are true?

A Only 1

B Only 2

C Both 1 and 2

D Neither 1 nor 2

💡 Short Explanation

Population change relies on natural change plus migration factors, not migration alone. Growth metrics are mathematically expressed in absolute figures or percentages. NCERT benchmarks evaluate both expressions for dynamic clarity.

✅ Correct Answer Explanation

Population growth is determined by two major sets of components: natural factors (births and deaths) and induced factors (migration). Statement 1 is false because it claims growth is calculated using only migration (inward and outward movement), completely ignoring vital statistics like birth and death rates. Statement 2 is entirely correct as demographers evaluate population shifts either through direct net additions (absolute numbers) or by determining its relative expansion pace over a base year value (percentage rate). Therefore, option B is the only logically sound choice.

❓ Why Other Options Are Incorrect

Option A → Incorrect because statement 1 misrepresents demographic inputs by eliminating natural components.
Option C → Incorrect because it validates statement 1 which completely overlooks reproductive variables.
Option D → Incorrect because it wrongly rejects statement 2, which is a standard metric expression in geography.

🎯 Strategy

Used: Elimination

Application: Filtering out statement 1 due to the restrictive word "only", which ignores core natural growth factors.

Final Logic: Eliminating statement 1 automatically removes options A and C, leaving statement 2 to confirm option B.

2 Match the demographic measurement to its correct description based on the chapter:

List-I	List-II
1. Absolute Number Growth	a. Calculated as $\frac{\left(P_{2}\ −\ P_{1}\right)}{P_{1}}\times 100$
2. Decadal Growth Rate (%)	b. The raw difference between the population of the present year and the base year
3. Positive Population Growth	c. Population of the later period is greater than the base period
4. Negative Population Growth	d. Population of the later period is lower than the base period

A 1-b, 2-a, 3-c, 4-d

B 1-a, 2-b, 3-d, 4-c

C 1-b, 2-d, 3-a, 4-c

D 1-a, 2-c, 3-b, 4-d

💡 Short Explanation

Absolute Number Growth measures the actual increase or decrease in population. Decadal Growth Rate expresses population change as a percentage of the base population. Positive Population Growth occurs when the later population exceeds the earlier population. Negative Population Growth occurs when the later population is less than the earlier population.

✅ Correct Answer Explanation

Population growth can be measured in both absolute and relative terms. Absolute Number Growth is obtained by subtracting the population of the base year ($P_{1}$) from that of the later year ($P_{2}$), giving the actual numerical increase or decrease (1 → b). The Decadal Growth Rate (%) measures this change relative to the base population using the formula $\frac{\left(P_{2}\ −\ P_{1}\right)}{P_{1}}\times 100$ which matches (2 → a). If the population in the later period is greater than the base period, it represents Positive Population Growth (3 → c). Conversely, if the later population is lower than the base period, it indicates Negative Population Growth (4 → d). Thus, the correct matching is 1-b, 2-a, 3-c, 4-d, corresponding to Option A.

❓ Why Other Options Are Incorrect

Option B: Incorrect because it reverses the definitions of absolute growth and growth rate and swaps positive and negative growth.
Option C: Incorrect because it incorrectly links the growth-rate concept with negative growth and mismatches the remaining definitions.
Option D: Incorrect because it assigns the formula to the wrong concept and mismatches the remaining population growth characteristics.

🎯 Strategy

Used: Formula and Concept Matching

Application: Match numerical difference with Absolute Growth, percentage formula with Growth Rate, increase with Positive Growth, and decrease with Negative Growth.

Final Logic:

Absolute Growth → Raw difference (b)
Growth Rate → Percentage formula (a)
Positive Growth → Later population higher (c)
Negative Growth → Later population lower (d)
This uniquely identifies Option A.

3 Arrange the steps a demographer would take to calculate the natural growth rate of a region:
1. Assess the crude death rate
2. Assess the crude birth rate
3. Find the difference between the two rates

A 2 → 1 → 3

B 3 → 1 → 2

C 1 → 3 → 2

D 2 → 3 → 1

💡 Short Explanation

Crude birth indices establish baseline population additions. Crude death indices measure baseline population subtractions. The natural balance equation subtracts mortality from fertility.

✅ Correct Answer Explanation

Natural growth rates capture demographic shifts excluding external migration inputs. To find this value, a demographer first needs to quantify the active entry points by assessing the crude birth rate (Step 2) and map the exit points via the crude death rate (Step 1). Once both independent indices are computed, the final operational step is finding the mathematical difference between these values (Step 3). This makes the 2, 1, 3 sequence the only operational progression.

❓ Why Other Options Are Incorrect

Option B → Incorrect because it seeks an operational difference before establishing the base values.
Option C → Incorrect because it attempts a comparative deduction before identifying the death rate.
Option D → Incorrect because it places the operational execution prior to gathering mortality statistics.

🎯 Strategy

Used: Operational Sequencing

Application: Ordering data aggregation steps before applying mathematical functions.

Final Logic: Values must be individually collected before a mathematical difference can be computed between them.

4 Which of the following scenarios serves as an example of an induced growth factor heavily influencing population numbers?

A An overall improvement in regional sanitation lowering the death rate.

B The influx of Tibetans and Bangladeshis contributing to high growth rates post-independence.

C A downward trend in crude birth rates due to female education.

D An increase in the mean age at marriage.

💡 Short Explanation

Induced population change relates directly to migration channels. Inbound movements create non-natural regional population spikes. Sanitation, education, and marriage directly regulate internal natural transitions.

✅ Correct Answer Explanation

Demographic literature splits growth into natural and induced streams. Natural growth deals exclusively with internal vital metrics like births and deaths. Induced growth represents external mobility factors altering settlement densities, specifically international or internal migration. The influx of migrants from Tibet and Bangladesh post-independence changed regional demographics through inbound relocation, making it a clear example of induced growth. All other choices reflect internal socio-medical factors that impact natural vital statistics.

❓ Why Other Options Are Incorrect

Option A → Incorrect because sanitation improvements modify natural mortality rates, not migration values.
Option C → Incorrect because female education alters natural fertility habits, not structural mobility.
Option D → Incorrect because marriage age structures relate to biological reproductive spans under natural changes.

🎯 Strategy

Used: Odd One Out

Application: Categorizing choices based on whether they affect internal biological rates or physical movement.

Final Logic: Three choices focus on biological rates, while option B isolates spatial relocation, identifying it as the induced factor.

🧠 Memory Trick

Induced is Inbound migration.

5 Which of the following statements analytically justifies why the 1901-1921 phase recorded a stagnant growth rate?
1. Exceptional improvements in healthcare counterbalanced high birth rates.
2. Inefficient food distribution systems and poor medical services caused death rates to remain almost as high as birth rates.
3. It recorded a negative growth rate during the 1911-1921 decade.

A 1 and 2 only

B 2 and 3 only

C 1 and 3 only

D 1, 2, and 3

💡 Short Explanation

Phase I highlights a period of stagnant demographic growth. High mortality rates counterbalanced high birth rates due to poor infrastructure. The decade of 1911-1921 showed an absolute negative decline.

✅ Correct Answer Explanation

The period from 1901 to 1921 is classified as Phase I of Indian population growth, marked by a stagnant or stationary growth pattern. Statement 1 is historically incorrect because healthcare infrastructure was severely lacking, not exceptionally improved. Statement 2 is correct because poor sanitation, food insecurity, and minimal medical coverage kept mortality rates high enough to match high birth rates. Statement 3 is also correct because the sub-period of 1911-1921 recorded an absolute negative growth rate (-0.31%) due to famines and epidemics. Thus, statements 2 and 3 provide the correct justification.

❓ Why Other Options Are Incorrect

Option A → Incorrect because it includes statement 1, which misrepresents early colonial health conditions.
Option C → Incorrect because it relies on statement 1 while omitting the structural explanation in statement 2.
Option D → Incorrect because it assumes all statements are true, overlooking the historical inaccuracy of statement 1.

🎯 Strategy

Used: Extreme Word Filter

Application: Spotting the historically inaccurate claim of "exceptional improvements" in colonial healthcare.

Final Logic: Eliminating statement 1 removes options A, C, and D, pointing directly to option B.

6 Fill in the blank: During 1911-1921, India recorded a ________ growth rate of (-) 0.31 per cent.

A Marginal positive

B Negative

C Stagnant but positive

D Exponential

💡 Short Explanation

The mathematical value is prefixed with a minus symbol. A minus sign indicates a net loss in population. This remains the only decade in census history showing an absolute reduction.

✅ Correct Answer Explanation

During the census decade of 1911-1921, severe epidemics (such as the influenza pandemic) and widespread crop failures caused high mortality across India. This resulted in a population decrease, leading to a growth rate of minus 0.31 percent. In demographics, any value below zero represents a negative growth rate, making option B the correct descriptor.

❓ Why Other Options Are Incorrect

Option A → Incorrect because a minus sign contradicts any form of positive calculation.
Option C → Incorrect because the value shows a decline rather than low positive stability.
Option D → Incorrect because exponential growth represents rapid, compounding increases.

🎯 Strategy

Used: Contextual Matching

Application: Linking the mathematical minus sign directly to its semantic equivalent.

Final Logic: A negative mathematical prefix requires the term "Negative" to describe the trend accurately.

🧠 Memory Trick

Minus sign means negative growth.

7 Consider the following statements about the 1921–1951 period:
1. The mortality rate dropped due to improved transport and communication systems facilitating better distribution.
2. It witnessed a sharp decline in the crude birth rate due to family planning policies.
3. The period is known as the phase of steady population growth because the death rate declined while the birth rate remained relatively high.

A 1 and 3 only

B 2 and 3 only

C 1 and 2 only

D 1, 2 and 3

💡 Short Explanation

Phase II (1921–1951) witnessed a decline in mortality due to improvements in transport, communication, and public health. Birth rates remained relatively high during this period. Family planning programmes were introduced only after 1952. Therefore, Statements 1 and 3 are correct, while Statement 2 is incorrect.

✅ Correct Answer Explanation

The period 1921–1951 is referred to as the Phase of Steady Population Growth in India. During this phase, mortality rates declined because improvements in transport, communication, medical facilities, and food distribution reduced deaths from famines and epidemics, making Statement 1 correct. Statement 2 is incorrect because India launched the world's first official National Family Planning Programme only in 1952, after this period. Hence, the crude birth rate remained relatively high throughout Phase II. Statement 3 is correct because the defining feature of this phase was declining death rates combined with persistently high birth rates, resulting in steady population growth. Therefore, the correct answer is Option A (1 and 3 only).

❓ Why Other Options Are Incorrect

Option B: Incorrect because Statement 2 is historically inaccurate, although Statement 3 is correct.
Option C: Incorrect because it includes Statement 2, which refers to a post-1952 development.
Option D: Incorrect because all three statements cannot be correct when Statement 2 is false.

🎯 Strategy

Used: Temporal Filter

Application: Verify whether each demographic event occurred during 1921–1951.

Final Logic: Improvements in transport and communication reduced mortality, while family planning belongs to the post-1952 period. Thus, only Statements 1 and 3 are correct.

🧠 Memory Trick

Family Planning → Starts in 1952

8 The steady population growth between 1921 and 1951 despite the Great Economic Depression is an example of what demographic principle?

A Mortality decline from infrastructural improvement overtaking economic stagnation's impact on population.

B Economic depression directly causing higher fertility rates.

C World Wars inducing mass inbound migration.

D Stagnant birth rates resolving food distribution inefficiencies.

💡 Short Explanation

Sanitation and transport improvements reduced overall mortality rates. This mortality decline sustained population growth despite economic crises. Infrastructure changes had a greater impact than economic shocks during Phase II.

✅ Correct Answer Explanation

During Phase II (1921-1951), India experienced steady population growth despite global economic issues like the Great Depression. This growth occurred because improvements in sanitation, public health, and transport infrastructure reduced mortality rates across the country. This downward trend in deaths had a stronger demographic impact than economic stagnation, allowing the population to grow steadily. Option A correctly explains this relationship.

❓ Why Other Options Are Incorrect

Option B → Incorrect because economic depressions generally lower birth rates rather than increasing them.
Option C → Incorrect because the World Wars did not cause large-scale migration into India.
Option D → Incorrect because changing birth rates do not fix supply chain issues.

🎯 Strategy

Used: Causality Matching Application: Identifying the main driver of Phase II growth, which was a decline in mortality. Final Logic: Option A is the only choice that correctly highlights the drop in mortality as the driver of growth.

9 Consider the following statements regarding the 1951-1981 population explosion phase:
1. The average annual growth rate reached as high as 2.2 per cent.
2. A centralized planning process effectively suppressed fertility rates.
3. Living conditions improved, leading to a high natural increase. Which statements are correct?

A 1 and 2 only

B 2 and 3 only

C 1 and 3 only

D 1, 2, and 3

💡 Short Explanation

Phase III is known as the population explosion phase. The annual growth rate peaked at 2.2 percent during this time. Improved living conditions reduced mortality while fertility rates stayed high.

✅ Correct Answer Explanation

The period 1951-1981 is known as Phase III, or the population explosion phase, driven by a rapid drop in mortality alongside high fertility rates. Statement 1 is correct because the average annual growth rate reached 2.2 percent. Statement 2 is incorrect because early centralized planning focused on infrastructure and health, which lowered death rates but did not immediately reduce birth rates. Statement 3 is correct because better living conditions led to a large natural increase. Thus, statements 1 and 3 are correct.

❓ Why Other Options Are Incorrect

Option A → Incorrect because it includes statement 2, which contradicts the concept of an explosion.
Option B → Incorrect because it includes statement 2 and leaves out the growth rate fact in statement 1.
Option D → Incorrect because it assumes all statements are true, overlooking the error in statement 2.

🎯 Strategy

Used: Logic Check

Application: Identifying contradictions between a "population explosion" and "suppressed fertility."

Final Logic: An explosion cannot happen if fertility is suppressed, which makes statement 2 false and leaves option C.

🧠 Memory Trick

Explosion Phase: High growth (2.2%) and better living conditions.

10 Arrange the following historical factors in the causal sequence that led to the Phase III population explosion:
1. Introduction of developmental activities through centralized planning
2. Rapid fall in mortality rate while fertility remained high
3. Improvement of living conditions of people at large

A 1 → 3 → 2

B 2 → 1 → 3

C 3 → 2 → 1

D 1 → 2 → 3

💡 Short Explanation

Centralized planning introduced new development policies after independence. These development programs helped improve general living conditions. Better living conditions led to a drop in death rates, causing the population explosion.

✅ Correct Answer Explanation

The population explosion in Phase III was driven by a clear sequence of events. It began with the introduction of developmental policies through centralized Five-Year Plans (Step 1). These policies improved healthcare, food security, and general living standards (Step 3). As a result, the mortality rate dropped quickly while birth rates stayed high, leading to the population explosion (Step 2). This makes 1, 3, 2 the correct causal sequence.

❓ Why Other Options Are Incorrect

Option B → Incorrect because the drop in mortality was a result of development, not the start of it.
Option C → Incorrect because living conditions improved due to planning, not before it.
Option D → Incorrect because the drop in mortality happened after living conditions improved, not before.

🎯 Strategy

Used: Cause and Effect

Application: Sorting steps from the root cause to the final demographic outcome.

Final Logic: Government planning (1) led to better living conditions (3), which resulted in lower death rates (2).

11 Match the socio-demographic indicators with their resulting impact during the post-1981 phase.

List-I	List-II
1. Increase in the mean age at marriage	a. Downward trend of crude birth rate
2. Education of females	b. Greater awareness and acceptance of family planning
3. Improved healthcare facilities	c. Decline in the crude death rate
4. Declining population growth rate (Post-1981)	d. Result of falling birth rates along with low death rates

A 1-a, 2-b, 3-c, 4-d

B 1-c, 2-a, 3-b, 4-d

C 1-a, 2-c, 3-d, 4-b

D 1-b, 2-d, 3-a, 4-c

💡 Short Explanation

Increasing the average age at marriage reduces fertility and lowers the crude birth rate. Female education promotes awareness of family planning and smaller family norms. Better healthcare reduces mortality, leading to a lower crude death rate. During the post-1981 phase, population growth slowed because birth rates declined while death rates remained low.

✅ Correct Answer Explanation

The post-1981 phase (Phase IV) of India's demographic transition is characterized by a gradual decline in the population growth rate. An increase in the mean age at marriage shortened the reproductive span of women, contributing to a decline in the crude birth rate (1 → a). Female education improved awareness regarding health, contraception, and family planning, encouraging smaller families (2 → b). At the same time, improved healthcare facilities reduced mortality through better medical services, immunization, and disease control, resulting in a decline in the crude death rate (3 → c). Together, declining birth rates and already low death rates led to the slowing of population growth after 1981 (4 → d). Thus, the correct matching is 1-a, 2-b, 3-c, 4-d, corresponding to Option A.

❓ Why Other Options Are Incorrect

Option B: Incorrect because it links the age at marriage with declining death rates and misplaces the effects of female education.
Option C: Incorrect because it incorrectly associates female education with healthcare outcomes and mismatches the demographic impacts.
Option D: Incorrect because it reverses the relationships between education, marriage age, healthcare, and population growth.

🎯 Strategy

Used: Cause-and-Effect Matching

Application: Match each demographic indicator with its direct demographic outcome during the post-1981 phase.

Final Logic:

Later marriage → Lower birth rate (a)
Female education → Family planning awareness (b)
Healthcare → Lower death rate (c)
Lower birth rate + Low death rate → Slower population growth (d)
This uniquely identifies Option A.

12 Which of the following analytical statements explains the paradox of Phase IV (Post-1981)?
1. The growth rate started slowing down gradually, but absolute population numbers continued to increase heavily.
2. The slowing down is attributed to a massive surge in mortality rather than declining birth rates.
3. Even with a lower growth rate, a large population base resulted in substantial absolute population addition.

A 1 and 3 only

B 2 and 3 only

C 1 and 2 only

D 1, 2 and 3

💡 Short Explanation

Phase IV witnessed a decline in the population growth rate. However, India's large population base continued to generate high absolute population additions. The slowdown resulted from declining birth rates, not rising mortality. Therefore, Statements 1 and 3 are correct, while Statement 2 is incorrect.

✅ Correct Answer Explanation

The post-1981 phase (Phase IV) is characterized by a gradual decline in India's population growth rate. Statement 1 is correct because, although the percentage growth rate slowed, the country's already enormous population base meant that even a smaller percentage increase produced a large absolute increase in population. Statement 2 is incorrect because the decline in the growth rate was not caused by a rise in mortality. Instead, it resulted mainly from a declining crude birth rate, supported by increased literacy, later marriages, improved family planning, and socio-economic development. Statement 3 is also correct because it explains the demographic paradox: a lower growth rate applied to a very large population still produces substantial additions in absolute numbers. Therefore, Statements 1 and 3 are correct, making Option A the correct answer.

❓ Why Other Options Are Incorrect

Option B: Incorrect because Statement 2 wrongly attributes the slowdown to increasing mortality.
Option C: Incorrect because it includes Statement 2, which is factually incorrect.
Option D: Incorrect because Statement 2 is false; therefore, all three statements cannot be correct.

🎯 Strategy

Used: Base Population Analysis

Application: Distinguish between percentage growth and absolute population increase by considering the effect of a large population base.

Final Logic: A lower growth rate on a very large population still results in substantial population additions, while declining birth rates—not higher mortality—explain the slowdown.

13 Fill in the blank: Kerala registered the lowest growth rate of ________ per cent not only in the southern group of states but also in the country as a whole during 1991-2001.

A 9.4

B 17.64

C 21.54

D 24.66

💡 Short Explanation

Kerala has consistently maintained low growth rates due to social development. During the 1991-2001 decade, its growth rate fell to single digits. The exact historical figure recorded for the state was 9.4 percent.

✅ Correct Answer Explanation

During the 1991-2001 period, southern states showed slower population growth compared to other parts of the country. Kerala recorded the lowest decadal growth rate in India at 9.4 percent. This low rate was largely due to high literacy, widespread female education, and effective healthcare access. The other options represent higher growth rates from other states or national averages.

❓ Why Other Options Are Incorrect

Option B → Incorrect because 17.64 percent is closer to the national average for a later decade (2001-2011).
Option C → Incorrect because 21.54 percent reflects the national decadal average for the 1991-2001 period.
Option D → Incorrect because 24.66 percent represents the higher growth rates seen in northern states.

🎯 Strategy

Used: Fact Verification

Application: Matching the lowest recorded state growth rate with the lowest percentage among the choices.

Final Logic: Since Kerala had the lowest growth rate in the country, it must match the lowest value option, 9.4%.

14 Consider the continuous belt of states comprising Gujarat, Maharashtra, Rajasthan, Punjab, Haryana, UP, MP, and West Bengal. Which statement characterizes this region's growth during 1991-2001?
1. It maintained a low rate of growth not exceeding 20 per cent.
2. It recorded a relatively high growth rate averaging 20-25 per cent.
3. Its growth was solely driven by international migration.

A 1 and 3

B Only 2

C 2 and 3

D Only 1

💡 Short Explanation

This northern and western belt showed higher growth rates than the south. The average decadal growth rate for these states was between 20 and 25 percent. This growth was driven by natural increase rather than international migration alone.

✅ Correct Answer Explanation

During the 1991-2001 decade, India showed clear regional differences in population growth. While southern states stayed below 20 percent, a continuous belt of northern, central, and western states—including Gujarat, Maharashtra, Rajasthan, Punjab, Haryana, UP, MP, and West Bengal—recorded higher growth rates, averaging between 20 and 25 percent. Statement 2 describes this correctly. Statement 3 is incorrect because the growth was mainly due to high natural birth rates, not international migration. Thus, only statement 2 is correct.

❓ Why Other Options Are Incorrect

Option A → Incorrect because this region exceeded 20 percent growth, and statement 3 is false.
Option C → Incorrect because it includes statement 3, which exaggerates the impact of international migration.
Option D → Incorrect because it relies on statement 1, which understates the region's actual growth rate.

🎯 Strategy

Used: Extreme Word Filter

Application: Identifying and removing statement 3 because of the restrictive word "solely."

Final Logic: Removing statement 3 eliminates options A and C; knowing the region had high growth confirms option B.

📄 Passage

"During 2001-2011, the growth rates of almost all States and Union Territories have registered a lower figure compared to the previous decade, namely, 1991-2001. The percentage decadal growth rates of the six most populous States, namely, Uttar Pradesh, Maharashtra, Bihar, West Bengal, Andhra Pradesh and Madhya Pradesh have all fallen during 2001-2011 compared to 1991-2001, the fall being the lowest for Andhra Pradesh (3.5% percentage points) and highest for Maharashtra (6.7 percentage points)."

According to the passage, which analytical conclusion can be drawn about the six most populous states between 2001 and 2011?

A Their absolute population decreased uniformly.

B They experienced negative decadal growth rates.

C The velocity at which their populations grew decelerated compared to the previous decade.

D Andhra Pradesh recorded the highest absolute population fall.

💡 Short Explanation

The passage states that decadal growth rates fell across these states. A falling growth rate means population growth slowed down. The population was still growing, but at a slower pace.

✅ Correct Answer Explanation

The passage notes that the percentage decadal growth rates for the six most populous states all fell during 2001-2011 compared to 1991-2001. A drop in the growth rate means that while the total population kept increasing, it did so at a slower pace than before. This indicates that the velocity of population growth decelerated, which matches option C.

❓ Why Other Options Are Incorrect

Option A → Incorrect because a lower growth rate does not mean a decrease in the absolute population.
Option B → Incorrect because the rates fell but remained positive, meaning growth did not turn negative.
Option D → Incorrect because Andhra Pradesh had the smallest drop in its growth rate, not the largest absolute decrease.

🎯 Strategy

Used: Contextual Matching

Application: Understanding that a drop in a growth rate means growth is slowing down.

Final Logic: A decline in percentage growth points directly to deceleration, confirming option C.

🧠 Memory Trick

Fallen rates mean slower growth velocity.

📄 Passage

Based strictly on the passage provided, what was the difference in the rate of fall (percentage points) between Maharashtra and Andhra Pradesh?

A 10.2 percentage points

B 3.2 percentage points

C 6.7 percentage points

D 3.5 percentage points

💡 Short Explanation

Maharashtra's growth rate fell by 6.7 percentage points. Andhra Pradesh's growth rate fell by 3.5 percentage points. The difference between these two values is 3.2 percentage points.

✅ Correct Answer Explanation

According to the passage, the drop in the decadal growth rate was 6.7 percentage points for Maharashtra and 3.5 percentage points for Andhra Pradesh. To find the difference between the two, subtract Andhra Pradesh's value from Maharashtra's: 6.7 - 3.5 = 3.2 This makes 3.2 percentage points the correct answer, matching option B.

❓ Why Other Options Are Incorrect

Option A → Incorrect because it adds the two values ($6.7 + 3.5 = 10.2$) instead of finding the difference.
Option C → Incorrect because it only lists the value for Maharashtra.
Option D → Incorrect because it only lists the value for Andhra Pradesh.

🎯 Strategy

Used: Substitution / Calculation

Application: Extracting the numbers from the text and running the required subtraction.

Final Logic: Subtracting 3.5 from 6.7 yields 3.2, which matches option B.

💡 Short Explanation

Poor nutrition and maternal mortality mainly affect adolescent mothers and young women. Skill development and entrepreneurship are essential for the youth workforce. Anaemia and reproductive health are major concerns among adolescent girls. Productive employment is necessary to harness India's demographic dividend.

✅ Correct Answer Explanation

Different demographic groups face distinct developmental challenges. Low nutrient intake and high maternal mortality primarily affect adolescent mothers and young females (1 → a), making maternal health a major policy concern. The need for skill development and entrepreneurship is most relevant to the youth workforce (15–29 years), enabling productive employment and economic growth (2 → b). Adolescent girls are particularly vulnerable to anaemia and poor reproductive health, making (3 → c) the correct match. India's large working-age population presents a demographic dividend only when supported by adequate employment opportunities. Therefore, employment generation and productive utilization of the demographic dividend correspond to the young working-age population (4 → d). Thus, the correct matching is 1-a, 2-b, 3-c, 4-d, which corresponds to Option A.

❓ Why Other Options Are Incorrect

Option B: Incorrect because it reverses the health and employment-related groups and mismatches the remaining categories.
Option C: Incorrect because it incorrectly links entrepreneurship with adolescent girls and anaemia with the youth workforce.
Option D: Incorrect because it swaps maternal health, employment, and demographic dividend categories.

🎯 Strategy

Used: Contextual Matching

Application: Associate health-related issues with adolescent females and employment-related issues with the youth and working-age population.

Final Logic:

Maternal mortality → Adolescent mothers (a)
Skill development → Youth workforce (b)
Anaemia → Adolescent girls (c)
Demographic dividend → Young working-age population (d)
This uniquely identifies Option A.

🧠 Memory Trick

Demographic Dividend → Workers (d)

18 Consider the following statements about the demographic composition of adolescents in India (2011):
1. The total share of adolescents is exactly one-third of India's population
2. Male adolescents constitute a higher percentage (52.7%) than female adolescents (47.3%).
3. Juvenile delinquency and drug abuse are cited as challenges regarding this demographic.

A 1 and 2 only

B 2 and 3 only

C 1 and 3 only

D 1, 2, and 3

💡 Short Explanation

According to the 2011 Census, adolescents constitute about one-fifth of India's population, not one-third. Male adolescents form a slightly higher share than females, and issues like juvenile delinquency and drug abuse are recognized social concerns. Therefore, Statements 2 and 3 are correct, while Statement 1 is incorrect.

✅ Correct Answer Explanation

As per the 2011 Census, adolescents (age group 10–19 years) account for approximately 20.9% (about one-fifth) of India's total population. Therefore, Statement 1 is incorrect because it wrongly states that adolescents form one-third of the population. Statement 2 is correct because male adolescents constitute 52.7%, while female adolescents account for 47.3%, indicating a slightly higher proportion of males. Statement 3 is also correct as social issues such as juvenile delinquency, substance abuse, and risky behaviour are recognized challenges faced by adolescents in India. Hence, only Statements 2 and 3 are correct, making Option B the correct answer.

❓ Why Other Options Are Incorrect

Option A (1 and 2 only) is incorrect because Statement 1 is false while Statement 2 is true.
Option C (1 and 3 only) is incorrect because Statement 1 is false even though Statement 3 is correct.
Option D (1, 2, and 3) is incorrect because Statement 1 overstates the adolescent population share.

🎯 Strategy

Used: Elimination

Application: Verify census-based demographic proportions and compare them with the given statements.

Final Logic: Adolescents form about one-fifth of the population (not one-third), while gender distribution and social challenges are correctly stated, confirming Option B.

🧠 Memory Trick

1/5 population, boys slightly more, and real social issues exist.

19 If a country maintains a constant annual growth rate of 1.64%, the mathematical calculation to determine when its population will jump from 1.2 billion to 2.4 billion is an example of applying which concept?

A Induced migration calculation

B Population doubling time

C Agricultural density measurement

D Decadal growth rate percentage

💡 Short Explanation

Going from 1.2 billion to 2.4 billion means the population is doubling. The time it takes for a population to double at a constant growth rate is its doubling time. This is a standard concept used to evaluate long-term population growth.

✅ Correct Answer Explanation

Population doubling time is defined as the time it takes for a population to double its size at a constant annual growth rate. In this example, moving from 1.2 billion to 2.4 billion is a exact doubling of the population. Calculating how long this takes based on the 1.64% annual growth rate is a direct application of the population doubling time concept, making option B correct.

❓ Why Other Options Are Incorrect

Option A → Incorrect because migration calculations focus on movement across borders, not total population doubling.
Option C → Incorrect because agricultural density measures population relative to cultivated land area.
Option D → Incorrect because decadal growth rates measure the percentage change over a fixed ten-year period.

🎯 Strategy

Used: Logic Check

Application: Recognizing that a change from 1.2 to 2.4 represents a 2x increase.

Final Logic: A 2x increase means the population is doubling, which points directly to the concept of doubling time.

🧠 Memory Trick

1.2 to 2.4 is double, so it is doubling time.

20 Fill in the blank: Population doubling time is intricately linked to the ________ annual growth rate, which for India was 1.64 per cent in 2011. Options:

A Absolute

B Historical

C Current

D Projected

💡 Short Explanation

Doubling time is calculated based on recent, active growth rates. India's annual growth rate was recorded at 1.64 percent in 2011. This rate reflects the current pace of growth at the time of calculation.

✅ Correct Answer Explanation

Population doubling time is a projection calculated using the current annual growth rate of a country. It estimates how long it would take for the population to double if that current rate stays the same. In 2011, India's current annual growth rate was 1.64 percent. This makes option C the correct choice, as the calculation relies on the active, current rate rather than historical or absolute figures.

❓ Why Other Options Are Incorrect

Option A → Incorrect because absolute numbers show total growth but cannot be used directly as a percentage rate in the doubling formula.
Option B → Incorrect because historical rates reflect past trends rather than the rate used for future doubling projections.
Option D → Incorrect because projected rates are estimates for the future, whereas doubling time is calculated using the current observed rate.

🎯 Strategy

Used: Contextual Matching

Application: Identifying that census records like the 2011 data provide the active, current rate for calculations.

Final Logic: The calculation uses the current rate to estimate future doubling times, making option C correct.

🧠 Memory Trick

Current rates determine future doubling times.
