    3. Cloze Test :
    Directions(1 - 10): In the following passage there are blanks each of which has been numbered, these numbers are printed below the passage and against each five words have been suggested, one of which fits the blanks appropriately. Find out the appropriate word in each case.
    Given the (1) of black money in the economy is large, even though declining, and that a large part of these transactions take place in cash, it is natural the government would want to find ways to deal with this. The finance secretary, for instance, has said that one of the (2) being considered is that no one paying a bill of more than Rs.5,000 in a restaurant should be allowed to do so in cash—once the amount is paid by credit or debit card, it automatically leaves a trail for the taxman to (3) since bank accounts have PAN card details. At some point, presumably, the same principle needs to be extended to luxury boutiques/shops and showrooms for automobiles, among others. The finance secretary, in fact, has said the government will set up a committee to suggest ways to incentivize credit and debit card transactions. One of them, he said, could be to share the costs of the Point of Sale device; greater spread of the RuPay cards could be another, (4) their charges are lower. Another suggestion made has been to limit the amount of cash that can be (5) while purchasing property. While discouraging the use of cash is a good thing, it is unlikely incentivizing the use of credit/debit cards is going to be of much use. A person buying a house or a luxury car, or paying for an expensive meal in a luxury hotel in cash is not doing so to avoid paying the service charge levied by Visa or MasterCard—the idea is to avoid getting (6) in the tax net.
    It is equally important to recognize that (7) mandating some things will not help. There is, for instance, no way of ensuring a limit, of say Rs.50,000, for the cash payment on the purchase of a flat as long as the registration is being done at a lower value than the actual one. The only way to check this is to do other reforms like lowering stamp duties, (8) circle rates with market values and refuse to recognize power of attorneys as proof of sale. The other, and more sensible, way is to make use of the troves of information the government already (9) by way of annual information returns from jewellers, real estate firms, automobile dealers, hotels, property registrars, travel agents and airlines among others. Once a profile is available of large spenders, this needs to be (10) with the income tax returns..

    People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost-saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
    Communication is a critical thing in today’s society because the exchange of information is vital in living. People live both locally and globally through technological connections by maintaining contact and interaction between individuals from all corners of the world. Communication binds people, helps maintaining the society healthy and enables people to interact and make friends from different regions and cultures. According to Adrian in 2006, communication and information technology plays a great role in the individuals’ life. There is a high rate of growth of the communication technology industry and the benefits as more people come up with new means of communication by day. A point has reached where activities cannot function without information technology due to the many benefits which come along with the current day technologies. Moreover, the industry plays a great role in improving the nation’s economy by facilitating fast and easier means of doing things and offering employment to many people across the world.
    The presence of computers, phones, internet and wireless devices have broadened the web of connectivity by changing long distances to short ones where everyone is equal distance from the other through the present connections. Living without technology will be totally impossible as this has become every day’s application as more and more people are gaining knowledge on how to make use of the communication tools to improve their ways of living and staying informed on the current technology to avoid being left behind. New technologies are being developed daily which shows that the industry will continue to grow and expand. People will continue using these technologies to improve their standards and to stay informed.
    The present technology has found its use in almost every sector making the industries, businesses and institutions to use it for their daily activities since it brings a lot of benefits. In the former days the modes of communication used were slow and sometimes unreliable since the information could take a long time before getting to the recipient. The use of communication and interaction sites such as Facebook, You Tube, Twitter, MySpace, and online email chat services has gained popularity among the young people whereby they can talk, share and interact with people from different parts of the word. The communication channels helps many users since they act as the dating sites for couples, people also make friends and share t with them at different locations. Many people have ended up in marriages from the online dating services; others have made friends and got connections to good jobs and other beneficial activities. These sites are more addictive and therefore the users find themselves visiting them more often and others stay online 24 hours. Apart from benefiting the communication sector, technology has also led to the improvement in areas of business, education, health, and the society in general. Businesses continue to enjoy the introduction of new technologies which help in improving their activities. Business remains up-to-date with the daily occurrences concerning the market; the business also moves forward and is able to compete with the others in different locations. In the education sector, technology continues to evolve at a faster rate as the learners get to know new ways of learning. The information technology is a requirement for every learner in order to utilize these ideas in the learning process. Students and their teachers communicate using the sites stated above to inform them on the changes in the timetable and send notes in soft copy. In addition technology has helped the health centres improve their services and transforming the medical profession by securing the environment for the patients and make them feel comfortable to discuss their issues.
    Moreover, there are online medical services whereby the patients can interact with their doctors without having to go to the health centres. Communication technology helps in the growth of the society through offering convenience modes of attending to the activities through online shopping, banking and travel arrangements. Also, there is speed in doing various operations in presence of technology whereby individuals attend to their tasks in a convenient and reliable way. Alternatively, people in the society keep in touch with one another and can effectively communicate and exchange their views for the growth and development of the community.
    Life is incomplete without technology and the world has reached a point that technology is everything. Incorporating technology in our daily activities makes the life easier and worth living. There is a need for the involved parties in the field of communication technology to come up with more advanced technologies so that people can enjoy these services and help in developing the country. People living in the third world countries have the duty to ensure that they have the knowledge of the current technology so that they can improve their countries to develop and compete with the developed nations. Comparing the advanced technology with the old fashion ways of doing things it has become simplified and time-saving. People are able to do many activities at a go, while in the absence of technology things went slow and more energy was utilized. Despite the few problems posed by the use of communication technology people continue to use it since the advantages outweighs the disadvantages..

Technology has many advantages and if used properly can make everyone’s life easier C. Technology is very important for communication D. Technology is going to be needed by everyone. E. None of the above Solution: B The author is trying to emphasize on the fact that technology plays a vital role in our life and that it is going to make life ‘worth living’. He thinks that even the most underdeveloped countries can be improved due to technology. The author talks about ‘disadvantages of communication technology’. Hence, the first option does not talk about technology, but only about communication technology. Options 3 and 4 are stressed in other paragraphs but the last paragraph does not focus on these points.
    8. What is the primary purpose of the passage? a. To show how technology is a part of everything in life b. To point out the disadvantages of technology c. To show how technology can further improve our lives A. Only c B. Only a C. a and c D. Only b E. All of the above Solution: B The passage mainly shows us how technology has an impact on life today. The past and present ways of communication have been compared and impact of technology in all parts of today’s world is shown. Nothing about ‘further development’ of technology has been mentioned. Option B stating about disadvantages is also incorrect.
    9. What should people living in the third world countries do? A. Migrate to developed nations B. Start taking loans to develop technology C. Make their economy stronger D. Try to learn about current technology E. None of the above Solution: D It is mentioned in the passage that, ‘People living in the third world countries have the duty to ensure that they have the knowledge of the current technology’. Hence, option 4 is the most appropriate option. The author has not mentioned ‘migration’ or ‘loans’ or ‘economy’ in any part of the passage.

    1. Number System :
    Number systems problems includes basic arithmetic, decimals, percentages, ratios, H.C.F & L.C.M and discounts.
    1. Sum of a rational number and its reciprocal is 13/6. Find the number A) 2 B) 3/2 C) 4/2 D) 5/2 Answer: B
    2. The LCM of two numbers is 280 and their ratio is 7:87:8. The two numbers are A) 70, 80 B) 35, 40 C) 42, 48 D) 28, 32 Answer: B
    2. Percentages :
    a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", or the abbreviations "pct.", "pct"; sometimes the abbreviation "pc" is also used.
    What percentage of numbers from 1 to 70 have 1 or 9 in the unit's digit? A) 1 B) 14 C) 20 D) 21 Answer: C Solution: Clearly, the numbers which have 1 or 9 in the unit's digit, have squares that end in the digit 1. Such numbers from 1 to 70 are 1, 9, 11, 19, 21, 29, 31, 39, 41, 49, 51, 59, 61, 69. Number of such number = 14 Required percentage = (14/70 x 100)% = 20%.
    3. Probability :
    A table or an equation that links each outcome of a statistical experiment with its probability of occurrence is known as a probability distribution.The topics covered in Probability Distribution are
    1)Quantity A:The probability that a word selected from the set of all rearrangements of the letters of the word "Math" results in "Math" Quantity B:The probability that a word selected from the set of all rearrangements of the letters of the word "Good" results in "Good" A. Quantity A is greater B. Quantity B is greater C. The two Quantities are equal D. The relationship cannot be determined E. None of these Answer: B Solution: Quantity A: Compute the number of ways the letters of the word 'Math' can be reordered . All 4 letters of the word 'Math' are distinct. The letters of the word 'Math' can therefore, be reordered in 4! Ways = 24 ways. Therefore, the probability that a word selected out of the 24 turns out to be 'Math' Quantity B: Two of the 4 letters of the word 'Good' repeat. The letters of the word 'Good' can therefore, be reordered in = 12 ways. Therefore, the probability that a word selected out of the 12 turns out to be 'Good' is 1/12
    4. Relationship between numbers :
    This one of the simple concept in mathematics and candidate can easily get good score in this area.
    Examples: 1) If one-third of one-fourth of a number is 15, then three-tenth of that number is: A. 35 B. 36 C. 45 D. 54 Answer: D
    2) Three times the first of three consecutive odd integers is 3 more than twice the third. The third integer is: A. 9 B. 11 C. 13 D. 15 Answer: D
    4. Time and Distance :
    Distance = Speed * TimeWhich implies Speed = Distance / Time and Time = Distance / Speed Let us take a look at some simple examples of distance, time and speed problems.
    Example: 1. A boy walks at a speed of 4 kmph. How much time does he take to walk a distance of 20 km? Solution: Time = Distance / speed = 20/4 = 5 hours.
    2. A cyclist covers a distance of 15 miles in 2 hours. Calculate his speed. Solution: Speed = Distance/time = 15/2 = 7.5 miles per hour.
    5. Ratios :
    To express the relative sizes, the ratio of one quantity to another is used. Ratio is often expressed in the form of a fraction.
    1. There are 12 oranges and 20 apples. What is the ratio of oranges to apples? Solution: Ratio = of/to 12/20 = 6/10 = 3/5 = 3 :: 5 = Oranges :: Apples
    2. The ratio of boys to girls is 3 to 4. If there are 135 boys, how many girls are there? Solution: Use cross multiplication 3/4 = 135/girls (4 x 135) = (3 x girls) = 540 540 / 3 = girls girls = 180 There are 180 girls.
    6. Arithmetic sequence :
    A arithmetic progression is a succession of numbers such that the distinction between the continuous terms is steady. Examples:
    1)Find the common difference and the next term of the following sequence: 3, 11, 19, 27, 35,__________. Answer: To find the common difference, I have to subtract a successive pair of terms. It doesn't matter which pair I pick, as long as they're right next to each other. To be thorough, I'll do all the subtractions: 11 – 3 = 8 19 – 11 = 8 27 – 19 = 8 35 – 27 = 8 => The difference is always 8, so the common difference is d = 8. => They gave me five terms, so the sixth term of the sequence is going to be the very next term. I find the next term by adding the common difference to the fifth term: 35 + 8 = 43 Then my answer is:Common difference: d = 8 Sixth term: 43
    2)Find the next term in the sequence 7, 15, 23, 31, __ ? Answer: First, find the common difference among each pair of consecutive numbers. 15−7 = 8 23−15 = 8 31−23 = 8 Since the common difference is 8 or written as d = 8, we can find the next term after 31 by adding 8 to it. Therefore, we have 31 + 8 = 39.
