QUESTION: 4

A string of three English letters is formed as per the following rules :
(a) The first letter is any vowel.
(b) The second letter is m, n or p.
(c) If the second letter is m then the third letter is any vowel which is different from the first letter.
(d) If the second letter is n then the third letter is e or u.
(e) If the second letter is p then the third letter is the same as the first letter.

Q. How many strings of letters can possibly be formed using the above rules ?

Solution:

D is the correct option.There are exclusive cases:
(i) when m is the second letter(ii) when n is the second letter(i) when p is the second letter

Case (i): First letter can be selected in 5 ways out of t vowels. Since second letter is fixed (i.e., m) therefore no. of
ways of selection of second letter is 1.
Third letter can be selected in 4 ways out of remaining 4 vowels (since the vowel which has been used at first place can
not be used at the place of third letter.
∴ Total no. of ways =5×1×4=20

Case (ii): First letter can be selected in 5 ways.Second letter can be selected in 1 way.Third letter can be selected in 1 way.Since third letter will be same as the first letter. So if the first letter is selected, then there is no need to select
the third letter.
∴ Total no. of ways =5×1×1=5
Hence , sum of all the possible no. of ways in which the string of letters can be formed
=20+10+5=35

QUESTION: 5

(d) If the second letter is n then the third letter is e or u.
(e) If the second letter is p then the third letter is the same as the first letter.

Q. How many strings of letters can possibly be formed using the above rules such that the third letter of the string is e ?

Solution:

C is the correct option.
1st letter 2nd letter 3rd letter     Total No of ways
a,i,o,u     m     e                    4×1×1=4
a,e,i,o,u     n     e         5×1×1=5
e          p          e              1×1×1=1
Total no of ways =10

QUESTION: 22

For achieving inclusive growth there is critical need to rethink the role of the State. The early debate among economists about the size of the Government can be misleading. The need of the hour is to have an enabling Government. India is too large and complex a nation for the State to be able to deliver all that needed. Asking the Government to produce all the essential goods, create all the necessary jobs, and keep a curb on the prices of all goods is to lead to a large cumbersome bureaucracy and widespread corruption. The aim must be to stay with the objective of inclusive growth that was laid down by the founding fathers of the nation and also to take a more modern view of what the State can realistically deliver. This is what leads to the idea of an enabling State, that is, a Government that does not try to directly deliver to the citizens everything that they need. Instead, it (1) creates an enabling ethos for the market so that individual enterprise can flourish and citizens can, for the most part, provide for the needs of one another, and (2) steps in to help those who do not manage to do well for themselves, for there will always be individuals, no matter what the system, who need support and help. Hence we need a Government that, when it comes to the market, sets effective, incentive-compatible rules and remains on the sidelines with minima interference, and, at the same time, plays an important role in directly helping the poor by ensuring that they get basic education and health services and receive adequate nutrition and food.

Solution:
QUESTION: 29

It is essential that we mitigate the emissions of greenhouse gases .and thus avoid some of the worst impacts of climate change that would take place in coming years and decades. Mitigation would require a major shift in the way we produce and consume energy. A shift away from overwhelming dependence on fossil fuels is now long overdue, but unfortunately, technological development has been slow arid inadequate largely because government policies have not promoted investments in research and development, myopically as a result of relatively low prices of oil. It is now, therefore, imperative for a country like India treating the opportunity of harnessing renewable energy on a large scale as a national imperative. This country is extremely well endowed with solar, wind and biomass sources of energy. Where we have lagged, unfortunately, is in our ability to develop and to create technological solutions for harnessing these resources.
One particular trajectory for carrying out stringent mitigation of greenhouse gas emissions assessed by the Inter-governmental Panel on Climate Change (IPCC) clearly shows the need for ensuring that global emissions of greenhouse gases peak no later than 2015 and reduce rapidly thereafter. The cost associated with such a trajectory is truly modest" and would amount, in the estimation of IPCC, to not more than 3 percent of the global GDP in 2030. In other words, the level of prosperity that the world would have reached without mitigation would at worst be postponed by a few months or a year at the most. This is clearly not a very high price to pay for protecting hundreds of millions of people from the worst risks associated with climate change. Any such effort, however, would require lifestyles to change appropriately also. Mitigation of greenhouse gas emissions is not a mere technological fix, and clearly requires changes in lifestyles and transformation of a country's economic structure, whereby effective reduction in emissions is brought about, such as through the consumption of much lower quantities of animal protein. The Food and Agriculture Organization (FAO) has determined that the emissions from the livestock sector amount to 18 percent of the total. The reduction of emissions from this source is entirely in the hands of human beings, who have never questioned the impacts that their dietary habits of consuming more and more animal protein are bringing about. Mitigation overall has huge co-benefits, such as lower air pollution and health benefits, higher energy security and greater employment.

Q.

According to the passage, which of the following would help in the mitigation of greenhouse gases?
1. Reducing the consumption of meat
2. Rapid economic liberalization
3. Reducing the consumerism
4. Modern management practices of livestock

Modern science is built on the process of posing hypotheses and testing them against observations—in essence, attempting to show that the hypotheses are incorrect. Nothing brings more recognition than overthrowing conventional wisdom. It is accordingly unsurprising that some scientists are skeptical of the widely accepted predictions of global warming. What is instead remarkable is that with hundreds of researchers striving to make breakthroughs in climatology, very few find evidence that global warming is unlikely.

The information above provides the most support for which one of the following statements?

Further, an electroshock system would administer shocks to the driver if he or she exceeds the speed limit or engages in other urtsafe driving practices.

In declaring that the radical new safe driving plan will help to reduce accident rates, the author assumes which of the following?

Solution:
QUESTION: 43

It is exceedingly difficult to make people realize that an evil is an evil. For instance, we seize a man and deliberately do him a malicious injury: say, imprison him for years. One would not suppose that it needed any exceptional clearness of wit to recognize in this an act of act of diabolical cruelty. But in England such a recognition provokes a stare of surprise, followed by an explanation that the outrange is punishment or justice or something else that is all right, or perhaps by a heated attempt to argue that we should all be robbed and murdered in our beds if such senseless villainies as sentences of imprisonment were not committed daily. It is useless to argue that even if this were true, which it is not, the alternative to adding crimes of our own to the crimes from which we suffer is not helpless submission. Chickenpox is an evil; but if I were to declare that we must either submit to it or else repress it by seizing everyone who suffers from it and punishing them by inoculation with smallpox, I should be laughed at; for though nobody could deny that the result would be to prevent chickenpox to some extent by making people avoid it much more carefully, and to effect a further apparent prevention by making them conceal it very anxiously, yet people would have sense enough to see that the deliberate propagation of smallpox was a creation of evil, and must therefore be ruled out in favour of purely humane and hygienic measures. Yet in the precisely parallel case of a man breaking into my house and stealing my diamonds I am expected as a matter of course to steal ten years of his life. If he tries to defeat that monstrous retaliation by shooting me, my survivors hang him. The net result suggested by the police statistics is that we inflict atrocious injuries on the burglars we catch in order to make the rest take effectual precautions against detection; so that instead of saving our diamonds from burglary we only greatly decrease our chances of ever getting them back, and increase our chances of being shot by the robber.
But the thoughtless wickedness with which we scatter sentences of imprisonment is as nothing compared to the stupid levity with which we tolerate poverty as if it were either a wholesome tonic for lazy people or else a virtue to be embraced as St Francis embraced it. If a man is indolent, let him be poor. If he is drunken, let him be poor. If he is not a gentleman, let him be poor. If he is addicted to the fine arts or to pure science instead of to trade and finance, let him be poor. If he chooses to spend his wages on his been and his family instead of saving it up for his old age, let him be poor. Let nothing be done for ‘the undeserving’ let him be poor. Serve him right! Also – somewhat inconsistently – blessed are the poor!

QUESTION: 49

Individuals, groups and leaders who promote human development operate under strong institutional, structural and political constraints that affect policy options. But experience suggests broad principles for shaping an appropriate agenda for human development. One important finding from several decades of human development experience is that focusing exclusively on economic growth is problematic. While we have good knowledge about how to advance health and education, the causes of growth are much less certain and growth is often elusive. Further, an unbalanced emphasis on growth is often associated with negative environmental consequences and adverse distributional effects.
The experience of China, with its impressive growth record, reflects these broader concerns and underlines the importance of balanced approaches that emphasize investments in the non-income aspects of human development.

Q.

With reference to the above passage, consider the following statements:
1. In developing countries, a strong institutional framework is the only requirement for human development and policy options
2. Human development and economic growth are not always positively inter-related.
3. Focusing only on human development should be the goal of economic growth

Which of the above statements is/are correct ?

QUESTION: 51

India's sub standard performance in the farm sector are inadequate since India is placed favourably when compared to China in terms of quantity and quality of arable land, average farm size and farm mechanization. The reasons for China having out performed India are technological improvements accruing from research and development, investment in rural infrastructure research and an increasingly liberalized agricultural policy moving away from self-sufficiency to leveraging the competitive advantage with a focus on "efficiency as much as equity." Investment in rural infrastructure, roads, storage facilities, marketing facilities are also crucial but government support in India has mainly been through subsidies, not investment. Subsides are against the market reforms and distort the market as well as reduce resource efficiency. In contrast, to the large number of applications for registration of new plant varieties in China over the past few years, data reveals that despite India having the largest number of agricultural scientists in the world, India's current research track is abysmal, equivalent to what China achieved in the 1980s.

Climate change is already making many people hungry all over the world, by disrupting crop yields and pushing up prices. And it is not just food but nutrients that are becoming scarcer as the climate changes. It is the poorest communities that will suffer the worst effects of climate change, including increased hunger and malnutrition as crop production and livelihoods are threatened. On the other hand, poverty is a driver of climate change, as desperate communities resort to unsustainable use of resources to meet current needs.

Solution:
QUESTION: 55

Accountability, or the lack of it, in governance generally, and civil services, in particular, is a major factor underlying the deficiencies in governance and public administration. Designing an effective framework for accountability has been a key element of the reform agenda. A fundamental issue is whether civil services should be accountable to the political executive of the day or to society at large. In other words, how should internal and external accountability be reconciled? Internal accountability is sought to be achieved by internal performance monitoring, official supervision by bodies like the ---Central-Vigilance Commission-and-Comptroller and Auditor—General, and judicial review of executive decisions. Articles 311 and 312 of the Indian Constitution provide job security and safeguards to the civil services, especially the All India Services. The framers of the Constitution had envisaged that provision of these safeguards would result in a civil service that is not totally subservient to the political executive but will have the strength to function in larger public interest. The need to balance internal and external accountability is thus built into the Constitution. The issue is where to draw the line. Over the years, the emphasis seems to have tilted in favour of greater internal accountability of the civil services to the political leaders of the day who in turn are expected to be externally accountable to the society at large through the election process. This system for seeking accountability to Society has not worked out, and has led to several adverse consequences for governance.
Some special measures can be considered for improving accountability in civil services. Provisions of articles 311 and 312 should be reviewed and laws and regulations framed to ensure external accountability of civil services. The proposed Civil Services Bill seeks to address some of these requirements. The respective roles of professional civil services and the political executive should he defined so that professional managerial functions and management of civil services are depoliticized. For this purpose, effective statutory civil service boards should be created at the centre and in the states. Decentralization and devolution of authority to bring government and decision making closer to the people also helps to enhance accountability.

Q.

According to the passage, which of the following factor/factors led to the adverse consequences for governance/public administration?
1. Inability of civil services to strike a balance between internal and external accountabilities
2. Lack of sufficient professional training to the officers of All India Services
3. Lack of proper service benefits in civil services
4. Lack of Constitutional provisions to define the respective roles of professional civil services vis-a-vis political executive in this context

QUESTION: 61

In a certain month. Mr. Khan's call charges were Rs 124.80. If in addition to the telephone rent of Rs.380, he has to pay 5% tax on the total amount, then what is his telephone bill for that month?

Solution:

Mr khan's call charges were Rs. 124.80
Telephone rent is Rs. 380.00
So Total amount = 380 + 124.80
= Rs. 504.80
He has to pay 5% tax on the total amount i.e. on Rs. 504.80

So Telephone bill for that month = Rs. 504.80 + Rs. 25.24
= Rs. 530.04
