Q1
Reading ComprehensionReading ComprehensionInference
PASSAGE

The main threat to maintaining progress in human development comes increasingly from the unsustainability of production and consumption patterns. Current production models rely heavily on fossil fuels. We now know that this is unsustainable because the resources are finite. The close link between economic growth and greenhouse gas emissions needs to be severed for human development to become truly sustainable. Some developed countries have begun to alleviate the worst effects by expanding recycling and investing in public transport and infrastructure. But most developing countries are hampered by the high costs and low availability of clean energy sources. Developed countries need to support developing countries' transition to sustainable human development.

Unsustainability in production pattern is due to which of the following?

1. Heavy dependence on fossil fuels

2. Limited availability of resources

3. Expansion of recycling

Select the correct answer using the code given below.

A1 and 2 only
B2 only
C1 and 3 only
D1, 2 and 3
Show answer & explanation
ANSWERA
EXPLANATION

The passage directly attributes unsustainability to heavy fossil-fuel dependence and finite resources. Expansion of recycling is presented as a mitigating response, not a cause.

PASSAGE

The main threat to maintaining progress in human development comes increasingly from the unsustainability of production and consumption patterns. Current production models rely heavily on fossil fuels. We now know that this is unsustainable because the resources are finite. The close link between economic growth and greenhouse gas emissions needs to be severed for human development to become truly sustainable. Some developed countries have begun to alleviate the worst effects by expanding recycling and investing in public transport and infrastructure. But most developing countries are hampered by the high costs and low availability of clean energy sources. Developed countries need to support developing countries' transition to sustainable human development.

Consider the following statements: Developed countries can support developing countries' transition to sustainable human development by

1. making clean energy sources available at low cost

2. providing loans for improving their public transport at nominal interest rates

3. encouraging them to change their production and consumption patterns

Which of the statements given above is/are correct?

A1 only
B1 and 2 only
C2 and 3 only
D1, 2 and 3
Show answer & explanation
ANSWERD
EXPLANATION

The passage says developing countries face high clean-energy costs, and it calls for support to sustainable transition. It also identifies unsustainable production and consumption patterns as a problem; the intended passage-based reading treats all three as support measures.

Q3
Reading ComprehensionReading ComprehensionInference
PASSAGE

Unless the forces and tendencies which are responsible for destroying the country's environment are checked in the near future and afforestation of denuded areas is taken up on a massive scale, the harshness of the climatic conditions and soil erosion by wind and water will increase to such an extent that agriculture, which is the mainstay of our people, will gradually become impossible. The desert countries of the world and our own desert areas in Rajasthan are a grim reminder of the consequences of large-scale deforestation. Pockets of desert-like landscape are now appearing in other parts of the country including the Sutlej-Ganga Plains and the Deccan Plateau. Where only a few decades back there used to be lush green forests with perennial streams and springs, there is only brown earth, bare of vegetation, without any water in the streams and springs except in the rainy season.

According to the passage given above, deforestation and denudation will ultimately lead to which of the following?

1. Depletion of soil resource

2. Shortage of land for the common man

3. Lack of water for cultivation

Select the correct answer using the code given below.

A1 and 2 only
B2 and 3 only
C1 and 3 only
D1, 2 and 3
Show answer & explanation
ANSWERC
EXPLANATION

The passage explicitly mentions soil erosion and disappearance of perennial water sources, supporting 1 and 3. It does not say that deforestation causes shortage of land for the common man.

The successive multipliers are 1/2, 1, 3/2, 2, 5/2 and 3. Thus X = 75 x 3 = 225.

Q5
Quantitative AptitudeNumber SystemDivisibility

An Identity Card has the number ABCDEFG, not necessarily in that order, where each letter represents a distinct digit (1, 2, 4, 5, 7, 8, 9 only). The number is divisible by 9. After deleting the first digit from the right, the resulting number is divisible by 6. After deleting two digits from the right of original number, the resulting number is divisible by 5. After deleting three digits from the right of original number, the resulting number is divisible by 4. After deleting four digits from the right of original number, the resulting number is divisible by 3. After deleting five digits from the right of original number, the resulting number is divisible by 2. Which of the following is a possible value for the sum of the middle three digits of the number?

A8
B9
C11
D12
Show answer & explanation
ANSWERA
EXPLANATION

Applying the divisibility conditions successively constrains the ending digits and the remaining prefix. One valid arrangement gives the middle three digits a sum of 8; therefore 8 is a possible value.

Q6
Logical ReasoningDirection SenseDirection, Distance & Turns

Two friends X and Y start running and they run together for 50 m in the same direction and reach a point. X turns right and runs 60 m, while Y turns left and runs 40 m. Then X turns left and runs 50 m and stops, while Y turns right and runs 50 m and then stops. How far are the two friends from each other now?

A100 m
B90 m
C60 m
D50 m
Show answer & explanation
ANSWERA
EXPLANATION

Take the common starting direction as east. After the first 50 m, X's two turns place him 60 m north and then 50 m west; Y's turns place him 40 m south and then 50 m west. Their horizontal positions coincide and their vertical separation is 60+40=100 m.

Q8
Quantitative AptitudeNumber SystemNumber Properties & Patterns

A bill for Rs. 1,840 is paid in the denominations of Rs. 50, Rs. 20 and Rs. 10 notes. 50 notes in all are used. Consider the following statements:

1. 25 notes of Rs. 50 are used and the remaining are in the denominations of Rs. 20 and Rs. 10.

2. 35 notes of Rs. 20 are used and the remaining are in the denominations of Rs. 50 and Rs. 10.

3. 20 notes of Rs. 10 are used and the remaining are in the denominations of Rs. 50 and Rs. 20.

Which of the above statements are not correct?

A1 and 2 only
B2 and 3 only
C1 and 3 only
D1, 2 and 3
Show answer & explanation
ANSWERD
EXPLANATION

Let a,b,c be the numbers of Rs.50, Rs.20 and Rs.10 notes. From a+b+c=50 and 50a+20b+10c=1840, 4a+b=134. The only feasible solution is a=28,b=22,c=0, so all three stated alternatives are incorrect.

Q9
Quantitative AptitudeNumber SystemPowers & Exponents

Which number amongst 2^40, 3^21, 4^18 and 8^12 is the smallest?

A2^40
B3^21
C4^18
D8^12
Show answer & explanation
ANSWERB
EXPLANATION

Convert the powers to comparable magnitudes: 4^18=2^36 and 8^12=2^36, while 2^40 is larger. Also 3^21 is about 2^33.3, so 3^21 is the smallest.

Q10
Quantitative AptitudePermutation and CombinationNumber / Word Formation

The digits 1 to 9 are arranged in three rows in such a way that each row contains three digits, and the number formed in the second row is twice the number formed in the first row, and the number formed in the third row is thrice the number formed in the first row. Repetition of digits is not allowed. If only three of the four digits 2, 3, 7 and 9 are allowed to use in the first row, how many such combinations are possible to be arranged in the three rows?

A4
B3
C2
D1
Show answer & explanation
ANSWERC
EXPLANATION

Checking the possible three-digit first-row numbers formed from three of 2,3,7,9 and requiring its double and triple to use the remaining digits exactly once leaves two valid arrangements.

Q11
Reading ComprehensionReading ComprehensionMain Idea / Central Theme
PASSAGE

In simple matters like shoe-making, we think only a specially trained person will serve our purpose, but in politics, we presume that everyone who knows how to get votes knows how to administer a State. When we are ill, we call for a trained physician, whose degree is a guarantee of specific preparation and technical competence - we do not ask for the handsomest physician, or the most eloquent one. Well then, when the whole State is ill should we not look for the service and guidance of the wisest and the best?

Which one of the following statements best reflects the message of the author of the passage?

AWe assume that in a democracy, any politician is qualified to administer a State.
BPoliticians should be selected from those trained in administration.
CWe need to devise a method of barring incompetence from public office.
DAs voters select their administrators, the eligibility of politicians to administer a State cannot be questioned.
Show answer & explanation
ANSWERB
EXPLANATION

The analogy with trained craftsmen and physicians is used to argue that political administration also requires appropriate training and competence.

Q12
Reading ComprehensionReading ComprehensionInference
PASSAGE

The poverty line is quite unsatisfactory when it comes to grasping the extent of poverty in India. It is not only because of its extremely narrow definition of 'who is poor' and the debatable methodology used to count the poor, but also because of a more fundamental assumption underlying it. It exclusively relies on the notion of poverty as insufficient income or insufficient purchasing power. One can better categorize it by calling it income poverty. If poverty is ultimately about deprivations affecting human well-being, then income poverty is only one aspect of it. Poverty of a life, in our view, lies not merely in the impoverished state in which the person actually lives, but also in the lack of real opportunity given by social constraints as well as personal circumstances to choose other types of living. Even the relevance of low incomes, meagre possessions, and other aspects of what are standardly seen as economic poverty relate ultimately to their role in curtailing capabilities, i.e., their role in severely restricting the choices people have to lead variable and valued lives.

Why is the methodology adopted in India to count the 'poor' debatable?

AThere is some confusion regarding what should constitute the 'poverty line'.
BThere are wide diversities in the condition of the rural and urban poor.
CThere is no uniform global standard for measuring income poverty.
DIt is based on the proposition of poverty as meagre income or buying capacity.
Show answer & explanation
ANSWERD
EXPLANATION

The passage says the methodology is debatable because it rests on the narrow assumption that poverty is insufficient income or purchasing power.

Why is income poverty only one measure of counting the 'poor'?

AIt talks of only one kind of deprivation ignoring all others.
BOther deprivations in a human life have nothing to do with lack of purchasing power.
CIncome poverty is not a permanent condition, it changes from time to time.
DIncome poverty restricts human choices only at a point of time.
Show answer & explanation
ANSWERA
EXPLANATION

The passage treats income poverty as only one dimension because poverty also includes wider deprivations and constraints on human capabilities and choices.

What does the author mean by 'poverty of a life'?

AAll deprivations in a human life which stem not only from lack of income but lack of real opportunities
BImpoverished state of poor people in rural and urban areas
CMissed opportunities in diverse personal circumstances
DMaterial as well as non-material deprivations in a human life which restrict human choices permanently
Show answer & explanation
ANSWERA
EXPLANATION

The author defines poverty of life in terms of deprivation plus the lack of real opportunities to choose valued ways of living.

Q19
Logical ReasoningData SufficiencyTwo-Statement / Data Sufficiency

Consider the Question and two Statements given below:

Question: Is x an integer?

Statement-1: x/3 is not an integer.

Statement-2: 3x is an integer.

Which one of the following is correct in respect of the Question and the Statements?

AStatement-1 alone is sufficient to answer the Question
BStatement-2 alone is sufficient to answer the Question
CBoth Statement-1 and Statement-2 are sufficient to answer the Question
DBoth Statement-1 and Statement-2 are not sufficient to answer the Question
Show answer & explanation
ANSWERD
EXPLANATION

Neither statement forces x to be an integer. For example, x=1/2 satisfies both conditions, while an integer x=1 also satisfies both; therefore the data are insufficient.

Q21
Reading ComprehensionReading ComprehensionAssumption
PASSAGE

In some places in the world, the productivity of staples such as rice and wheat has reached a plateau. Neither new strains nor fancy agrochemicals are raising the yields. Nor is there much unfarmed land left that is suitable to be brought under the plough. If global temperature continues to rise, some places will become unsuitable for farming. Application of technology can help overcome these problems. Agricultural technology is changing fast. Much of this change is brought about by affluent farmers in the West/Americas. Techniques developed in the West are being adapted in some places to make tropical crops more productive. Technology is of little use if it is not adapted. In the developing world, that applies as much to existing farming techniques as it does to the latest advances in genetic modification. Extending to the smallholders and subsistence farmers of Africa and Asia the best of today's agricultural practices, in such simple matters as how much fertilizers to apply and when, would lead to a greatly increased availability of food for humanity. So would things like better roads and storage facilities, to allow for the carriage of surpluses to markets and reduce wastage.

Based on the above passage, the following assumptions have been made:

1. Development of agricultural technology is confined to developed countries.

2. Agricultural technology is not adapted in developing countries.

Which of the above assumptions is/are valid?

A1 only

Q31
Reading ComprehensionReading ComprehensionInference
PASSAGE

Natural selection cannot anticipate future environments on the earth. Therefore, the set of existing organisms can never be fully prepared for environmental catastrophes that await life. An outcome of this is the extinction of those species which cannot overcome environmental adversity. This failure to survive, in modern terms, can be attributed to the genomes which are unable to withstand geological vagaries or biological mishaps (infections, diseases and so on). In biological evolution on the earth, extinction of species has been a major feature. The earth may presently have up to ten million species, yet more than 90% of species that have ever lived on the earth are now extinct. Once again, the creationist doctrines fail to satisfactorily address why a divine creator will firstly bother to create millions of species and then allow them to perish. The Darwinian explanation for extinct life is once again simple, elegant and at once convincing - organisms go extinct as a function of environmental or biological assaults for which their inheritance deems them ill-equipped. Therefore, the so-called Darwinian theory of evolution is not a theory at all. Evolution happens - this is a fact. The mechanism of evolution (Darwin proposed natural selection) is amply supported by scientific data. Indeed, to date no single zoological, botanical, geological, paleontological, genetic or physical evidence has refuted either of the central two main Darwinian ideas. If religion is not taken into consideration, Darwinian laws are acceptable just like the laws proposed by Copernicus, Galileo, Newton and Einstein - sets of natural laws that explain natural phenomena in the universe.

According to the passage, natural selection cannot anticipate future environments on the earth as

1. Species not fully prepared to face the environmental changes that await them will face extinction

2. All the existing species would get extinct as their genomes will not withstand biological mishaps

3. Inability of the genome to withstand environmental changes would result in extinction

4. Extinction of species is a common feature

Therefore, the so-called Darwinian theory of evolution is not a theory at all. Evolution happens - this is a fact. The mechanism of evolution (Darwin proposed natural selection) is amply supported by scientific data. Indeed, to date no single zoological, botanical, geological, paleontological, genetic or physical evidence has refuted either of the central two main Darwinian ideas. If religion is not taken into consideration, Darwinian laws are acceptable just like the laws proposed by Copernicus, Galileo, Newton and Einstein - sets of natural laws that explain natural phenomena in the universe.

With reference to the passage, the following assumptions have been made:

1. Only species that have the ability to overcome environmental catastrophes will survive and perpetuate.

2. More than 90% of the species on the earth are in the danger of getting extinct due to drastic changes in the environment.

3. Darwin's theory explains all the natural phenomena.

Reading ComprehensionReading ComprehensionMain Idea / Central Theme
PASSAGE

With steady economic growth, higher literacy and increasing skill levels, the number of Indian middle-class families has gone up exponentially. Direct results of the affluence have been changes in dietary patterns and energy consumption levels. People have moved to a higher protein-based diet like milk products, fish and meat, all of which need significantly more water to produce than cereal based diets. Increasing use of electronic and electric machines/gadgets and motor vehicles needs more and more energy and generation of energy needs water.

Which one of the following statements best reflects the crux of the passage?

APeople should be persuaded to continue with the mainly Indian traditional cereal-based diets.
BIndia needs to focus on developing agricultural productivity and capacity for more energy generation in the coming years.
CModern technological developments result in the change of cultural and social behaviour of the people.
DWater management practices in India need to change dramatically in the coming years.

PASSAGE

Natural selection cannot anticipate future environments on the earth. Therefore, the set of existing organisms can never be fully prepared for environmental catastrophes that await life. An outcome of this is the extinction of those species which cannot overcome environmental adversity. This failure to survive, in modern terms, can be attributed to the genomes which are unable to withstand geological vagaries or biological mishaps (infections, diseases and so on). In biological evolution on the earth, extinction of species has been a major feature. The earth may presently have up to ten million species, yet more than 90% of species that have ever lived on the earth are now extinct. Once again, the creationist doctrines fail to satisfactorily address why a divine creator will firstly bother to create millions of species and then allow them to perish. The Darwinian explanation for extinct life is once again simple, elegant and at once convincing - organisms go extinct as a function of environmental or biological assaults for which their inheritance deems them ill-equipped.

PASSAGE

The demographic dividend, which has begun in India and is expected to last another few decades, is a great window of opportunity. The demographic dividend is basically a swelling in the working age population, which conversely means that the relative ratio of very young and very old will, for a while, be on the decline. From the experience of Ireland and China, we know that this can be a source of energy and an engine of economic growth. The demographic dividend tends to raise a nation's savings rate since in any nation, it is the working age population that is the main saver. And since the savings rate is an important driver of growth, this should help elevate our growth rate. However, the benefits of demographic dividend depend on the quality of the working age population. And this implies bringing back the importance of education, acquisition of skills and human capital.

Which of the following would invariably happen in a country, when the demographic dividend has begun to operate?

1. The number of illiterate people will decrease.

2. The ratio of very old and very young will decrease for a while.

Each of the six 3-digit permutations uses A, B and C once in each place across the set, so x=222(A+B+C). The minimum sum of three distinct non-zero digits is 1+2+3=6, giving the least 4-digit value 1332. Since x is always at least 1332, there is no 3-digit value such as 888. Hence statement 1 only is correct.

Quantitative AptitudeNumber SystemIntegers

Consider the following statements in respect of two natural numbers p and q such that p is a prime number and q is a composite number:

1. p x q can be an odd number.

2. q/p can be a prime number.

3. p + q can be a prime number.

Which of the above statements are correct?

A1 and 2 only
B2 and 3 only
C1 and 3 only
D1, 2 and 3
Show answer & explanation
ANSWERD
EXPLANATION

Examples show each statement can occur: an odd prime times an odd composite can be odd; a composite q can be p times another prime; and a prime plus an odd/even composite can yield a prime in suitable cases. Thus all three are possible.

Q69
Quantitative AptitudeMixture and AlligationReplacement

There are two containers X and Y. X contains 100 ml of milk and Y contains 100 ml of water. 20 ml of milk from X is transferred to Y. After mixing well, 20 ml of the mixture in Y is transferred back to X. If m denotes the proportion of milk in X and n denotes the proportion of water in Y, then which one of the following is correct?

Am = n
Bm > n
Cm < n
DCannot be determined due to insufficient data
Show answer & explanation
ANSWERA
EXPLANATION

After the first transfer, Y contains 20 ml milk and 100 ml water. The 20 ml returned to X contains 20/120 of milk, so X ends with 16 2/3 ml milk in 100 ml total; Y ends with the same proportion of water, 83 1/3/100. Hence the proportions are equal.

A112/9
B125/6
C155/9
D250/9
Show answer & explanation
ANSWERD
EXPLANATION

The given angles sum to 260 degrees, so A represents 100 degrees. Percentage = (100/360)x100 = 250/9 percent.

PASSAGE

To encourage research is one of the functions of a university. Contemporary universities have encouraged research, not only in those cases where research is necessary, but on all sorts of entirely unprofitable subjects as well. Scientific research is probably never completely valueless. However silly and insignificant it may seem, however mechanical and unintelligent the labours of the researchers, there is always a chance that the results may be of value to the investigator of talent, who can use the facts collected for him by uninspired but industrious researchers as the basis of some fruitful generalization. But where research is not original, but consists in the mere rearrangement of existing materials, where its object is not scientific but literary or historical, then there is a risk of the whole business becoming merely futile.

The author's assumption about scientific research is that

Ait is never very valuable
Bit is sometimes very valuable
Cit is never without some value
Dit is always very valuable
Show answer & explanation
ANSWERC
EXPLANATION

The passage says scientific research is 'probably never completely valueless' but allows that its value may depend on how it is used.

The author says there is always a chance that even seemingly silly or mechanical research may be useful to a talented investigator; 'can be of value' matches that qualification.

Q73
Reading ComprehensionReading ComprehensionInference
PASSAGE

How best can the problems of floods and droughts be addressed so that the losses are minimal and the system becomes resilient? In this context, one important point that needs to be noted is that India gets 'too much' water (about 75% of annual precipitation) during 120 days (June to September) and 'too little' for the remaining 245 days. This skewed water availability has to be managed and regulated for its consumption throughout the year.

Which one of the following best reflects the practical, rational and lasting solution?

AConstructing huge concrete storage tanks and canals across the country
BChanging the cropping patterns and farming practices
CInterlinking of rivers across the country
DBuffer stocking of water through dams and recharging aquifers
Show answer & explanation
ANSWERD
EXPLANATION

The passage identifies a strong seasonal mismatch between water supply and demand. Storing water and recharging aquifers addresses that imbalance across the year.
