Given:

Expression is 5 × 10 × 15 × 20 × 25 × 30 × 35 × 40 × 45 × 50

Concept used:

To find the number of zeroes at the end of the product, we need to calculate the number of 2’s and number 5’s or number of pairs of 2 and 5.

2 × 5 = 10 ⇒ Number of zeroes = 1 (number of pair = 1)

The number of pairs of 2 and 5 is same as the number of zeroes at the end of the product

Calculation:

5 × 10 × 15 × 20 × 25 × 30 × 35 × 40 × 45 × 50

⇒ 5¹⁰(1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10)

⇒ 5¹⁰(1 × 2 × 3 × 2 × 2 × 5 × 2 × 3 × 7 × 2 × 2 × 2 × 9 × 2 × 5)

⇒ 5¹²(1 × 2 × 3 × 2 × 2 × 2 × 3 × 7 × 2 × 2 × 2 × 9 × 2)

⇒ 5¹² × 2⁸ × 3² × 7 × 3²

There are only 8 pairs of 2 and 5 are possible

The given bar graph represents the information on the sources of irrigation in India in 2011. As per the graph, 4% of the water supply is from tanks, 30% from canals, 20% from open wells, 40% from tube wells and 6% from other sources. This study shows that the maximum amount of water supply (40%) relies on tube wells as they have the ability to supply water to a larger area, and are more useful in times of drought, when surface water sources dry up. However, it can be noticed that in close succession are sources such as canals (30%) and open wells (20%). Tanks (4%) are not preferred as they take up a lot of open space which could rather be used for agriculture.

My favorite teacher. She’s such a kind person, usually not a person of her words meaning she forgets a lot of things but it’s funny. She’s not old either early 40’s, and till this day people tease me saying we look alike and I’m “the daughter she never had” and I just think it’s funny now. She is a very caring person and she’s chill and laid back and nice with you unless you get on her nerves. She’s funny and she’s like a teenager because she likes to make puns and crack jokes, she also is always trying to be relatable which is comforting at times. She likes to comfort in the best of her ability and she’s super smart and likes to have fun and do fun stuff.

The given bar graph represents data regarding X standard students’ preference of subjects. The graph shows that 30% of the students prefer Maths, 35% prefer Science, 40% prefer Social Science, 60% prefer English, 70% prefer Kannada, 45% prefer Hindi and 65% prefer Physical Education. Based on the study, it can be derived that the most preferred language is Kannada (with 70%), most preferred subject is Social Science (with 40%), and additionally Physical Education is also preferred by a large percentage (with 65%). However, it can be noticed that languages (with 60%, 70% and 45%) are preferred over subjects (with 30%, 35% and 45%) by the class X students.

Time spent on chosen activities by Rural and Urban Women The bar graph indicates the time spent on activities like cooking, watching T.V., indulging in hobbies, rearing children, and reading, by rural and urban women. Surprisingly, in all the five areas, the urban women spend more time than the rural women. Perhaps the field work or other manual labor that the rural women take up, leaves them with little time for the chosen activities. On cooking, if the rural women spend less than one hour, the urban women spend nearly two hours. Similarly, if less than half an hour is spent on watching T.V. by the rural women, the time indicated against the urban women is nearly one and a half hours. If the rural women spend negligible time on their hobby, the urban women keep aside at least an hour for the same. The biggest gap is seen in the time taken on rearing children. If the rural women spend less than half an hour on rearing children, the urban women spend nearly two and a half hours on the same. The entry for reading is the lowest of all the activities for both rural and urban women. Understandably the urban women have a higher percentage in this area.

Comparative study of population growth in pre-independent and post-independent India Population growth has been a perpetual problem in India. A comparative study of the population growth in the pre – and post-independence India shows that population growth has been rapid in the post-independence era. In the preindependence era, between 1901 and 1940, there was a growth of only 0.5 crore. The growth was from 1 crore to 1.5 crore. However, in the post-independence era, on an average, in every decade there has been an increase of one crore. From 1951 to 2010, the increase has been from about 2 to over 6 crores. No wonder, India is a billion strong country.

Due to the current civilization progress in recent decades, acceleration of the development of industry, automotive, urban agglomerations, intensification of agricultural production, etc. and related greenhouse gas emissions, global warming, ozone layer depletion in the atecologicalecologicalmosphere, increase of environmental pollution, growing problem of smog in urban agglomerations, the increase in pollution of the seas and oceans to which unsorted waste is thrown away is cut out as part of the predatory economy of tropical forests in the Amazon and other largest natural forest ecosystems.

In addition, the secondary effect of global warming of the Earth's climate is the increasing, more frequent weather anomalies, including drought, leading to steppe and desertification of areas that were previously natural forest ecosystems or areas exploited by agriculture.

As a result of the above-mentioned processes, every year many species of flora and fauna disappear forever.

As a result, natural biodiversity diminishes, which for millions of years evolved evolutionally on Earth.

In this way the natural resources of the planet Earth are irretrievably in decline.

In view of the above, the issue of environmental protection and biodiversity is one of the most important challenges of humanity in the 21st century.

Classical economics must change towards a green economy based on the strategy of sustainable pro-ecological development.

Respected principal, teachers and my dear friends I ask all of you to close your eyes for a minute and imagine yourselves in the ICU of a hospital. Is it a nice feeling? I’m sure that all of you will reply in the negative. Friends, just imagine how much more unpleasant the reality would be if we were to actually lie in the ICU of a hospital. The thin line of difference between imagination and reality will vanish if we don’t care for road safety. Safety on the road is possible only if we follow traffic rules. The strange truth about traffic rules is that we need to be fined to take care of our own lives.

Take for example the seat belt rule. So many of us start pulling the seat belt on sighting a cop at a distance. Same is true of helmets. We jump traffic lights at points where there is no policeman. So many of us overtake others from the wrong side. We drive like lunatics even where the speed limit is supposed to be below 40 kms. an hour. We speak on the mobile phone while driving and worse still while riding a two wheeler as though there is an emergency.

Friends, let us remember that all traffic rules are chalked out with great care to save lives and avoid other tragic happenings like physical disabilities, loss of money etc. The traffic rules are simple rules that can be easily followed. When we violate these rules, we put to danger not only our lives, but also the lives of other innocent people.

Today we are celebrating ‘Road Safety Week’. Let us pledge today, as responsible citizens of India, that we would never break any traffic rule even when there is no fear of being fined. Thank you.

A survey was conducted by the Delhi based NGO (Centre for Media Studies) to know how voters are bribed during elections. It is a open secret that all the politicians in India bribe the voters to get votes in their favour. The graph indicates the extent to which it is being practiced in various states in India. It was found that Karnataka stood in the first place i.e 47%. of voters were bribed and Tamilnadu followed with about 34%, Madhya Pradesh 33%, Andhra Pradesh 31%, Orissa 27%, other states like Delhi 25%, Uttar Pradesh 18% and Maharastra 13% respectively. The survey revealed that we can find Karnataka as the most corrupted state and Maharastra as the least one. It is very clear that money plays is a very important role during the polling and the people who have enough money, would get power in their hands.

Honorable Chief Guest, respected Principal, my dear teachers and beloved friends, today is a great day for all of us as we are celebrating ‘Sports Day’. On this special occasion. I feel it is my privilege to speak a few words. The first requirement for a student is to be physically and mentally fit. He can never be successful in his life unless he has good health. There is a well known saying “Asound mind in a sound body”. For a healthy body, sports is essential. A student must participate in games and sports to keep himself fit and free from diseases. If his health is good he can concentrate on his studies and excel in all the other activities of his life. Besides, games and sports develop a sense of team spirit which helps them in their I future life.

Sports, whether indoor or outdoor, are equally good for a student. Outdoor games tone up the muscles and keep them fit whereas indoor games sharpen the mind. Sports plays very important role in our life and hence should be made an integral part of our dayto-day activities. It is a known fact that a sportsman gets name and fame in the society. And even i some reservations are there for sportsmen in public and private sectors. So they can claim their reservations and get a job easily. So I request all of you my dear friends to participate very actively in sports and get ourselves an all round development. 

Thank you.

He went into a crowded restaurant and ate a full meal. The meal and tea cost him eleven annas. When he put his hand in his coat pocket to pay, there was no wallet in his coat pocket. The restaurant owner did not trust him and forced him to remove his coat, shirt and shoes off.

One evening the narrator goes to a crowded restaurant to have his food and when he has to pay the bill of eleven annas, he realises that his purse with his life’s savings of fourteen rupees is missing. But, the owner of the restaurant thinks that the speaker is trying to cheat him, and threatens to gouge his eyes out. None of the others at the restaurant seem to have any kindness either.

The speaker pleads with the owner to keep his coat as surety. But, the owner guffaws and makes the speaker remove his coat, shirt, and shoes. When he wants the speaker to remove even the trousers, the speaker pleads with him for mercy saying he has nothing inside. This only invokes more laughter and the restaurant owner, along with fifty other people gathered there, forces the speaker to strip further saying mockingly, “There must be something inside.” The speaker, now resigned to his fate, starts unbuttoning his trousers, all the time imagining himself standing naked in front of others, with his eyes gouged out.

We see that the narrator is not only embarrassed but also humiliated. Since he is not a cheat, it must have been terribly embarrassing for him to have realised that he had eaten his food at the restaurant, but had no money to pay for the food. His embarrassment would have increased when the owner of the restaurant treated him as a cheat. But, to top it all, the cruel way in which not only the owner but also the people gathered there treated him would have been humiliating for the narrator.

Several factors led to the growth of feudalism. They differed from region to region and period to period. They are summarized as under.

1. During the rule of weak Kings the Provincial Officers obtained independent authority. The political rule became more decentralized to suit feudal rule. 

2. To protect themselves from the ‘Barbarian – invaders’ of Germanic tribes, the smaller land holders gave up their claims over their lands and surrendered them to the local Lords. This gave a sense of security of life and property and helped in the development of feudalism. 

3. The weakening of Kings’ control over the Vassals also lessened their control over the people. People were more loyally bound to the Lords, which strengthened feudalism.

4. The Kings were very much dependent on the Vassals to defend their Kingdom, whereas the vassals required the King’s legal sanction over their land. This mutual dependence strengthened feudalism.

5. It was impossible for Kings to control vast lands, as there were no adequate roads and means of transport. Moreover the financial burden of ruling over a vast Empire made it impossible fora united rule. 

6. The absence of a strong political system, insecurity of life and property made the presence of feudal Lords inevitable. These feudal lords took the responsibility of protecting the property of the people from thieves, bandits, invaders etc,. 

7. It was an agrarian society based on land. The King was the absolute land owner and he could only give lands as grants or ‘fiefs’ to the Lords in exchange of their services. The same system was followed down the line. Feudalism was also inevitable due to the absence of industries and the serfs were bound to the land.

Every human activity and accomplishment, with whatever high degree of perfection it might achieve, ends up in decay and disintegration as was the case with the Egyptian Civilization also. Many reasons are attributed to it. In brief, some of them are as given below. 

• The Rulers failed to bring a perfect and workable political system. 
• The weak Rulers were unable to maintain their authority and the feudal Lords gained control resulting in decay and disorder.
• The ruthless exploitation of lower class and religious intolerance resulted in disharmony and disunity in the society. 
• Internal quarrels among the Rulers led to disunity and disorder. 
• Invasions by uncivilized invaders from Africa and Assyria resulted in the demolition of . their temples and halt in the advancement. The invaders were more efficient in the art of warfare. 
• The material welfare and contented life discouraged independent thinking, resulting in decline.

The factors that helped the growth of civilizations are as follows: 

1. Deposition of fertile alluvial soil caused by the river floods. 

2. Continuous and un – interrupted supply of water for irrigation and domestic purposes. 

3. Favourable climate generally found on the river valleys. 

4. Plenty of food, fruits and vegetables for the humans and fodder for their animals. 

5. River valleys helped fishing. 

6. They helped the growth of trade and communication by providing means of transport.

Above factors reduced the burden of man in wandering for food and risk of life. There is a strong argument that “Men become more civilized if they have leisure to do creative work”. It is certain that river valleys provided them food in plenty and sufficient leisure to develop civilizations. Humans invented metals, made tools, were able to cultivate the land, built buildings in wood and stone, prepared vessels, boats, weapons, furniture, clothing, jewellery and many other things. 

1. Internal quarrels among the Rulers led to disunity and disorder. 

2. The Rulers failed to bring a perfect and workable political system.

The two rivers Euphrates and Tigris formed the fertile plains. Early tillers settled in villages. With the growth of population, these villages developed into towns and later into cities. These plains were the cradles of many civilizations which developed and later vanished during 3500 to 500 B.C.E. Hence, Mesopotamia is called as ‘Both the Cradle and Graveyard of Civilizations’.
