Read the following passages and answer the question that follows the passage. Your answer to these questions should be based on passage only.

Passage 1

Developed countries have made adequate provisions for social security for senior citizens. State insurers (as well as private ones) offer Medicare and pension benefits to people who can no longer earn. In India, with the collapse of the joint family system, the traditional shelter of the elderly has disappeared. And a State faced with a financial crunch is not in a position to provide social security. So, the working population should give serious thought to building a financial base for itself.

Q.31) Which one of the following if it were to happen, weakens the conclusion drawn in the above passage the most?

  1. The investable income of the working population, as a proportion of its total income, will grow in the future
  2. The insurance sector is underdeveloped and trends indicate that it will be extensively privatized in the future
  3. India is on a path of development that will take it to a developed country status, with all its positive and negative implications
  4. If the working population builds a stronger financial base, there will be a revival of the joint family system

Passage 2

Until the end of his first year at school, Cyril retained many of the pleasures and pursuits he had brought with him from home, and he kept an old interest in butterflies and fossils. His grandmother had presented him with a fine bird’s eggs cabinet, but he could never bring himself to risk in climbing trees. Once or twice he dissected dead birds from sheer determination to overcome his horror of the operation. Probably it was his envy of those physically unlike himself that brought on a phase during which he drew massive athletes with thick necks and square shoulders. Again he pitied himself for what he could never be.

Q.32) The reason Why Cyril made drawings of athletes was that

  1. though he admired them, he lacked a fine physique himself
  2. he loved violent exercises
  3. athletics was a passion with him
  4. he had to complete an assignment

Q.33) There are 4 members in a committee. If one of them is replaced by a younger member such that the average age of the committee is as it was 6 years ago. The new member is how many years younger than the member replaced?

  1. 42 years
  2. 24 years
  3. 6 years
  4. None of the above

Q.34) A group of eight students are experimenting in the laboratory. If the average reading of eight students is 35.5, the average reading of first two students is 28 and the average reading of next three students is 36, the reading of 6th student is 8 more than the seventh one and the eighth one is 8 more than the sixth one, then find the reading of the sixth student

  1. 40
  2. 49
  3. 56
  4. 39

Q.35) The average age of 3 children in a family is 20% of the average age of the father and the eldest child. The total age of the mother and the youngest child is 39 years. If the father’s age is 26 years, what is the age of the second child?

  1. 20 years
  2. 15 years
  3. 18 years
  4. Can’t be determined

What IMPACT can the ‘60 Day’ have on the final results? We will explain by taking a small example. Imagine you are sitting in the examination hall, appearing in Prelims Paper I. You have attempted 70 questions already but still unsure about a few. Then you stumble upon a question that was asked in 60 Day (and believe us, it has happened to hundreds of students countless times). You choose the right answer and submit your paper hoping for the best! Eventually, you go on to clear Mains as well as Personality Test and secure a good rank as well. When the cut off gets announced by UPSC, you realize that you have scored just one mark more than the cut off! Yes, that one mark can change your life (and it has done so to many of our students in the past). Now, imagine the kind of impact 60 to 80 marks can have! Isn’t that so fascinating to imagine?  

One’s level of preparedness is always different for different subjects. Even within a subject, one’s comfort level may vary with topics. For example, one might be more comfortable in solving questions of Polity than Economics and within Polity also, one might be at ease with questions on fundamental rights than Parliament. The level of comfort and ease that one has with a subject/ topic gets manifested in the examination. However, there is no conscious effort by aspirants to micro analyze these aspects. Now, coming to the second aspect i.e. the mistakes that one commits in answering MCQs, it can be said that there are mainly four reasons behind incorrect responses in the OMR sheet. They are:

  1. Lack of information
  2. Lack of analytical ability
  3. Silly mistakes
  4. Excessive risk-taking

Let’s analyze them one by one:

  1. Lack of information: You simply don’t know the information. You are clueless and that’s why you don’t attempt the question. For example, you may have never come across a regime called the ‘Wassenaar Agreement’ during your preparation and you can’t do much about it. The lack of information is pardonable and rectifiable. You can read more and gather more information. That is within your reach.
  2. Lack of analytical ability: You know the concept but the question is a twisted one and you are not able to apply the concept. For example, in a question asking you to identify the climate type of a region based on certain given parameters like precipitation, temperature, and air density, you might find it difficult to mark the correct option even if you are aware of all the options given in the question! That is clearly a lack of application and you can overcome it by developing a habit of framing questions in your mind while you study any topic.
  3. Silly mistakes: This habit is unpardonable. You know the concept, you become happy, you misread the question, you mark the incorrect answer and you are out of the race! Such mistakes reveal your hurriedness while answering the question. A simple mistake of reading ‘chose the incorrect option’ as ‘chose the correct option’ can destroy your chances. It means that you need to have patience and focus while attempting the paper.
  4. Excessive risk-taking: You are confused between the options and just in order to increase your attempts, you make wild guesses and try your luck only to repent eventually. Risk-taking is an art and one must be very careful while doing the guesswork in confusing questions. If you are not lucky enough, it can spoil your chances.

You will realize that these problems will have different meanings for different people. For example, one might find a lack of information as the main culprit in answering wrong the questions on Culture while in Polity, lack of analytical ability is usually the culprit. The point here is that you must analyse your preparation on these yardsticks by applying them on different subjects/ topics. If one is having a headache, he/ she can’t have the same medicine for fever. Isn’t it.

This is where our revamped ’60 Day’ comes into the picture. It will give you an opportunity to micro analyze your preparation and perform better in the examination.

Finally, it is up to you to take advantage of this framework. We are sure of only one thing- if you follow this program, assess yourself on the basis of the given framework and keep improving your weaker areas, success will be yours.

We are providing you with the right platform, the right guidance, and the right competition. Do you have the right motivation to make full use of this initiative? We think you have. Come, be a part of this initiative and take the first step towards SUCCESS!


Importance of self – tracking:

We could have provided all of you with login id and passwords to monitor your daily performance in the 60-day program.

Instead, a simple and most beautiful way which Disqus provides is profile based commenting!

Yes, we have seen the most successful candidates who have taken the maximum benefit from this program monitoring themselves by commenting on their answers in the box given (Disqus comment). And reviewing their performance themselves once in 10 days on the progress meter.
