38. Roy is now 4 year older than Erik and half of that amount than Lewis. If in two years Roy will be twice as old as Erick, then in two year what would be Roy age multiplied by Lewis age??
Ans is 48
Firstly two equations from 1st sentence...
Suppose Roy=x, Erik=y, Lewis=z
So x=y+4.... (1)
2nd is x=z+2... (2) (Roy is now 4 year older than Erik and half of that amount than Lewis so 4/2=2)
Also after 2 years Erik and Roy relation will b
X+2=2(y+2)... (3)
So put this into 1st equation. U will get y=2...
And then x=6, z=4(by substituting other)
Now asking multiplication after two years of Roy n Lewis is (6+2)*(4+2) =48...

13. A permutation is often represented by the cycles it has. For example, if we permute the
numbers in the natural order to 2 3 1 5 4, this is represented as (1 3 2) (5 4). In this the
(132) says that the first number has gone to the position 3, the third number has gone to
the position 2, and the second number has gone to position 1, and (5 4) means that the
fifth number has gone to position 4 and the fourth number has gone to position 5. The
numbers with brackets are to be read cyclically.
If a number has not changed position, it is kept as a single cycle. Thus 5 2 1 3 4 is
represented as (1345)(2).
We may apply permutations on itself If we apply the permutation (132)(54) once, we get
2 3 1 5 4. If we apply it again, we get 3 1 2 4 5 , or (1 2 3)(4) (5)

(#M40035115) AMCAT MATHS PUZZLE para (82) Keep an EYE

SINCE the late 1970s when the technology for sex determination first came into being, sex selective abortion has unleashed a saga of horror. Experts are calling it "sanitised barbarism". Demographic trends indicate the country is fast heading towards a million female foetuses aborted each year.
Although foetal sex determination and sex selection is a criminal offence in India, the practice is rampant. Private clinics with ultrasound machines are doing brisk business. Everywhere, people are paying to know the sex of an unborn child. And paying more to abort the female child. The technology has even reached remote areas through mobile clinics. Dr. Puneet Bedi, obstetrician and specialist in foetal medicine, says these days he hardly sees a family with two daughters. People are getting sex determination done even for the first child, he says.
Spreading like a virus
A recent media workshop on the issue of sex selection and female foeticide brought home the extent of the problem. Held in Agra in February, the workshop was organised by UNICEF, Business Community Foundation, and the Centre for Advocacy and Research. Doctors, social scientists, researchers, activists, bureaucrats, journalists told their stories of what they were doing to fight the problem.
If the 1991 Census showed that two districts had a child sex ratio (number of girls per thousand boys) less than 850; by 2001 it was 51 districts. Child rights activist Dr. Sabu George says foeticide is the most extreme form of violence against women. "Today a girl is several times more likely to be eliminated before birth than die of various causes in the first year. Nature intended the womb to be a safe space. Today, doctors have made it the most unsafe space for the female child," he says. He believes that doctors must be held responsible — "They have aggressively promoted the misuse of technology and legitimised foeticide."
Researchers and scholars use hard-hitting analogy to emphasise the extent of the problem. Dr. Satish Agnihotri, senior IAS officer and scholar who has done extensive research on the issue, calls the technology "a weapon of mass destruction". Dr. Bedi refers to it as genocide: "More than 6 million killed in 20 years. That's the number of Jews killed in the Holocaust."
Related issues
Foeticide is also one of the most common causes of maternal mortality. The sex of the foetus can be determined only around 14-16 weeks. This means most sex selective abortions are late. Abortion after 20 weeks is illegal in India. Donna Fernandes, Vimochana, a Bangalore-based NGO, says foeticide is related to a host of other social problems as varied as privatisation of medical education and dowry. Karnataka has the highest number of private medical colleges. Healthcare turning commodity has led to terrifying consequences. Adds Fernandes, "Wherever green revolution has happened foeticide has increased. With more landholdings and wealth inheritance dowry has increased. Daughters are considered an economic liability. Today, people don't want their daughters to study higher — a more well-educated groom will demand more dowry."
Ironically, as income levels increase, sex determination and sex selection is increasing. The most influential pockets have the worst sex ratios. Take Punjab for instance — 793 girls for every 1,000 boys against the national figure of 927. Or South Delhi — one of the most affluent localities of the Capital — 760. According to Satara-based advocate Varsha Deshpande, small families have come at the cost of the girl child.
In patriarchal States like Rajasthan where infanticide has existed for centuries, this new technology has many takers. Meena Sharma, 27, television journalist from Rajasthan, who did a series of sting operations across four States last year, says, "Today, people want to pretend they are modern and that they do not discriminate between a girl and a boy. Yet, they will not hesitate to quietly go to the next village and get an ultrasound done."
Sharma was determined to expose the widespread malpractice. She travelled with pregnant women as "decoys" across four States and more than 13,000 km to do a series of sting operations. She says more than 100 doctors of the 140 they met were ready to do a sex selective abortion, some as late as the seventh month. "We were shocked at the greed we saw — doctors did not even ask why we wanted to abort, far from dissuading us from doing so," she says.
What's the solution? Varsha Deshpande says the PCPNDT Act (Pre-Conception and Pre-Natal Diagnostic Techniques — Regulation and Prevention of Misuse) is very well conceived and easy to use. "We have done 17 sting operations across Maharashtra and got action taken against more than 25 doctors," says Varsha. She adds that other laws for violence against women such as dowry, domestic violence, rape, put the control in the hands of the police which is biased. Therefore, even though the law exists, offenders get away. This law preventing sex determination and sex selection is much easier to use, she says.
Regulating technology
Akhila Sivadas, Centre for Advocacy and Research, Delhi, agrees that the law is very well conceived and the need of the hour is legal literacy to ensure the law is implemented. "The demand and supply debate has been going on for some time. Doctors say there is a social demand and they are only fulfilling it. They argue that social attitudes must change. However, in this case supply fuels demand. Technology will have to be regulated. Technology in the hands of greedy, vested interests, cannot be neutral. There is a law to prevent misuse and we must be able to use it," she says. CFAR is currently partnering with local NGOs in six districts of Rajasthan to help ensure implementation of the law.
On the "demand" side, experts such as Dr. Agnihotri argue that women's participation in workforce, having disposable incomes and making a contribution to larger society will make a difference to how women are seen. Youth icons and role models such as Sania Mirza are making an impact, he says.
Others feel there needs to be widespread visible contempt and anger in society against this "genocide" — "the kind we saw against the Nithari killings," says Dr. Bedi. "Today nobody can say female foeticide is not their problem." Time we all did our bit to help save the girl child. Time's running out.

Answer the question based on the given passage

Management is a set of processes that can keep a complicated system of
people and technology running smoothly. The most important aspects of
management include planning, budgeting, organising, staffing,
controlling, and problem-solving. Leadership is a set of processes that
creates organisations in the first place or adapts them to significantly
changing circumstances. Leadership defines what the future should look
like, aligns people with that vision, and inspires them to make it happen
despite the obstacles. This distinction is absolutely crucial for our
purposes here: Successful transformation is 70 to 90 per cent leadership
and only 10 to 30 percent management. Yet for historical reasons, many
organisations today don't have much leadership. And almost everyone
thinks about the problem here as one of managing change. For most of
this country, as we created thousands and thousands of large
organisations for the first time in human history, we didn't have enough
good managers to keep all those bureaucracies functioning. So many
companies and universities developed management programs and
hundreds and thousands of people were encouraged to learn management
on the job. And they did. But, people were taught little about leadership.
To some degree, management was emphasised because it's easier to
teach than leadership. But even more so, management was the main item
on the twentieth-century agenda because that's what was needed. For
every entrepreneur or business builder who was a leader, we needed
hundreds of managers to run their ever-growing enterprises.
Unfortunately for us today, this emphasis on management has often been
institutionalised in corporate cultures that discourage employees from
learning how to lead. Ironically, past success is usually the key ingredient
in producing this outcome. The syndrome, as I have observed it on many
occasions, goes like this: success creates some degree of marked
dominance which in turn produces much growth. After a while keeping
the ever-larger organisation under control becomes the primary
challenge. So attention turns inward and managerial competencies are
nurtured. With a strong emphasis on management but not leadership,
bureaucracy and an inward focus takeover. But with continued success,
the result mostly of market dominance, the problem often goes
unaddressed and an unhealthy arrogance begins to evolve. All of these
characteristics then make any transformation effort much more difficult.
Arrogant managers can over-evaluate their current performance and
competitive position, listen poorly and learn slowly. Inwardly focused
employees can have difficulty seeing the very forces that present threats
and opportunities. Bureaucratic cultures can smother those who want to
respond to shifting conditions. And the lack of leadership leaves no force
inside these organisations to break out of the morass.

Q11. Why did companies and universities develop programmes to
prepare managers in such a large number?
a. (A) Companies and universities wanted to generate funds through these
programmes
b. (B) The large number of organisations were created as they needed
managers in good number
c. (C) Organisations did not want to spend their scarce resources in
training managers
d. (D) Organisations wanted to create communication network through
trained managers

Q12. How has the author defined management?
a. It is the process of adapting organisations to changing circumstances.
b. It is the system of aligning people with the direction it has taken.
c. It refers to creating a vision to help direct the change effectively.
d. Creating better performance through customer orientation.

Q13. What is the historical reason for many organisations not having
leadership?
a. A view that leaders are born, they are not made
b. Leaders lack managerial skills and organisations need managers
c. Leaders are weak in carrying out traditional functions of management
d. Leaders allow too much complacency in organisations


Q14. Which of the following characteristics help organisations in their
transformation efforts?
a. Emphasis on leadership but not management
b. A strong and dogmatic culture
c. Bureaucratic and inward looking approach
d. Failing to acknowledge the value of customers and shareholders


Q15. Which of the following is similar in meaning of the word 'smother'

Sixty years ago, on the evening of August 14, 1947, a few hours before Britain’s Indian Empire was formally divided into the nation-states of India and Pakistan, Lord Louis Mountbatten and his wife, Edwina, sat down in the viceregal mansion in New Delhi to watch the latest Bob Hope movie, “My Favorite Brunette.” Large parts of the subcontinent were descending into chaos, as the implications of partitioning the Indian Empire along religious lines became clear to the millions of Hindus, Muslims, and Sikhs caught on the wrong side of the border. In the next few months, some twelve million people would be uprooted and as many as a million murdered. But on that night in mid-August the bloodbath—and the fuller consequences of hasty imperial retreat—still lay in the future, and the Mountbattens probably felt they had earned their evening’s entertainment.
Mountbatten, the last viceroy of India, had arrived in New Delhi in March, 1947, charged with an almost impossible task. Irrevocably enfeebled by the Second World War, the British belatedly realized that they had to leave the subcontinent, which had spiralled out of their control through the nineteen-forties. But plans for brisk disengagement ignored messy realities on the ground. Mountbatten had a clear remit to transfer power to the Indians within fifteen months. Leaving India to God, or anarchy, as Mohandas Gandhi, the foremost Indian leader, exhorted, wasn’t a political option, however tempting. Mountbatten had to work hard to figure out how and to whom power was to be transferred.
The dominant political party, the Congress Party, took inspiration from Gandhi in claiming to be a secular organization, representing all four hundred million Indians. But many Muslim politicians saw it as a party of upper-caste Hindus and demanded a separate homeland for their hundred million co-religionists, who were intermingled with non-Muslim populations across the subcontinent’s villages, towns, and cities. Eventually, as in Palestine, the British saw partition along religious lines as the quickest way to the exit.
But sectarian riots in Punjab and Bengal dimmed hopes for a quick and dignified British withdrawal, and boded ill for India’s assumption of power. Not surprisingly, there were some notable absences at the Independence Day celebrations in New Delhi on August 15th. Gandhi, denouncing freedom from imperial rule as a “wooden loaf,” had remained in Calcutta, trying, with the force of his moral authority, to stop Hindus and Muslims from killing each other. His great rival Mohammed Ali Jinnah, who had fought bitterly for a separate homeland for Indian Muslims, was in Karachi, trying to hold together the precarious nation-state of Pakistan.
Nevertheless, the significance of the occasion was not lost on many. While the Mountbattens were sitting down to their Bob Hope movie, India’s constituent assembly was convening in New Delhi. The moment demanded grandiloquence, and Jawaharlal Nehru, Gandhi’s closest disciple and soon to be India’s first Prime Minister, provided it. “Long years ago, we made a tryst with destiny,” he said. “At the stroke of the midnight hour, while the world sleeps, India will awaken to life and freedom. A moment comes, which comes but rarely in history, when we step out from the old to the new, when an age ends, and when the soul of a nation, long suppressed, finds utterance.”
Posterity has enshrined this speech, as Nehru clearly intended. But today his quaint phrase “tryst with destiny” resonates ominously, so enduring have been the political and psychological scars of partition. The souls of the two new nation-states immediately found utterance in brutal enmity. In Punjab, armed vigilante groups, organized along religious lines and incited by local politicians, murdered countless people, abducting and raping thousands of women. Soon, India and Pakistan were fighting a war—the first of three—over the disputed territory of Kashmir. Gandhi, reduced to despair by the seemingly endless cycle of retaliatory mass murders and displacement, was shot dead in January, 1948, by a Hindu extremist who believed that the father of the Indian nation was too soft on Muslims. Jinnah, racked with tuberculosis and overwork, died a few months later, his dream of a secular Pakistan apparently buried with him.
Many of the seeds of postcolonial disorder in South Asia were sown much earlier, in two centuries of direct and indirect British rule, but, as book after book has demonstrated, nothing in the complex tragedy of partition was inevitable. In “Indian Summer” (Henry Holt; $30), Alex von Tunzelmann pays particular attention to how negotiations were shaped by an interplay of personalities. Von Tunzelmann goes on a bit too much about the Mountbattens’ open marriage and their connections to various British royals, toffs, and fops, but her account, unlike those of some of her fellow British historians, isn’t filtered by nostalgia. She summarizes bluntly the economic record of the British overlords, who, though never as rapacious and destructive as the Belgians in the Congo, damaged agriculture and retarded industrial growth in India through a blind faith in the “invisible hand” that supposedly regulated markets. Von Tunzelmann echoes Edmund Burke’s denunciation of the East India Company when she terms the empire’s corporate forerunner a “beast” whose “only object was money”; and she reminds readers that, in 1877, the year that Queen Victoria officially became Empress of India, a famine in the south killed five million people even as the Queen’s viceroy remained adamant that famine relief was a misguided policy.
Politically, too, British rule in India was deeply conservative, limiting Indian access to higher education, industry, and the civil service. Writing in the New York Tribune in the mid-nineteenth century, Karl Marx predicted that British colonials would prove to be the “unconscious tool” of a “social revolution” in a subcontinent stagnating under “Oriental despotism.” As it turned out, the British, while restricting an educated middle class, empowered a multitude of petty Oriental despots. (In 1947, there were five hundred and sixty-five of these feudatories, often called maharajas, running states as large as Belgium and as small as Central Park.)
