The student fest in an Ganguram Engineering College is to be held in one month's time and no sponsorship has yet been arranged by the students. Finally the General Secretary  of the student body took the initiative and decided to go alone for sponsorship collection. In fact, he is the only student doing t he fund raising job on the first day. However, seeing his enthusiasm, other students also joined him as follows: on the second day, 2 more students join him: on the third day. 3 more students join the group of the previous day, and so on. In this manner, the sponsorship collection is completed in exactly 20 days. If an MBA student is twice as efficient as an Engineering student, the number of days which ll MBA students would take to do the some activity, is:
  • a)
    70        
  • b)
    80        
  • c)
    90        
  • d)
    100
Correct answer is option 'A'. Can you explain this answer?

Here, 1st day raising fund= 1
2nd day raising fund by = 1 + 2
3rd day raising fund by = 1 + 2 + 3
4th day raising fund by = 1 + 2 + 3 + 4
5th day raising fund by = 1 + 2 + 3 + 4 + 5
.
.
.
20th day raising fund is completed
= 1 + 2 + 3 + 4 + 5 + ......... + 20
So, sequence is
= 1 + (1 + 2) + (1 + 2 + 3) + (1 + 2 + 3 + 4 + 5) +… … … (1 + 2 + 3 + 4 + 5 + … 20)
So, sequence is
= 1 + (1 + 2) + (1 + 2 + 3) + (1 + 2 + 3 + 4 + 5) +… … … (1 + 2 + 3 + 4 + 5 + … 20)
This can be written as 

We know that sum of square of natural number

Here n = 20

= So, total no of students = 1540
Now, Efficiency of MBA student is double as compared to B.Tech student.
no. of total days = 1540/2 x 11 = 70 days.

To solve this problem, let's break it down step by step:

Step 1: Understanding the given information
- The General Secretary of the student body started the sponsorship collection alone on the first day.
- On the second day, 2 more students joined him.
- On the third day, 3 more students joined the group of the previous day.
- This pattern continues until the sponsorship collection is completed in exactly 20 days.

Step 2: Finding the total number of students on the 20th day
- On the first day, there is 1 student.
- On the second day, there are 1 + 2 = 3 students.
- On the third day, there are 3 + 3 = 6 students.
- Continuing this pattern, on the 20th day, there will be 1 + 2 + 3 + ... + 19 + 20 students.
- The sum of the first n natural numbers is given by the formula: n(n+1)/2.
- So, on the 20th day, there will be 20(20+1)/2 = 210 students.

Step 3: Determining the efficiency of an MBA student compared to an Engineering student
- The problem states that an MBA student is twice as efficient as an Engineering student.
- This means that an MBA student can collect twice as much sponsorship as an Engineering student in the same amount of time.

Step 4: Calculating the number of days required for all MBA students to collect the same amount of sponsorship
- Since an MBA student is twice as efficient as an Engineering student, it would take half the time for an MBA student to collect the same amount of sponsorship.
- Therefore, the number of days required for all MBA students to collect the same amount of sponsorship would be 20/2 = 10 days.

Therefore, the correct answer is option A) 70, as an MBA student would take 10 days to complete the same activity.

Directions:Re ad the following case let and choose the best alternative.Mr. Rajiv Singhal, Chairman of the Board of Directors of Loha India Ltd., (a steel manufacturing company) had just been visited by several other directors of the company.The directors were upset with recent actions of the company president, Mr. Ganesh Thakur. They demanded that the board consider firing the president.Mr. Thakur, recently appointed as president, had undertaken to solve some of the management-employees problems by dealing directly with the individuals, as often as possible. The company did not have a history of strikes or any other form of collective action and was considered to have a good work culture. However, Mr. Thakur felt that by dealing directly with individuals, he could portray the management’s concern for the employees. An important initiative of Mr. Thakur was to negotiate wages of the supervisors with each supervisor. In these negotiation meetings he would not involve anyone else, including the Personnel Department which reported to him, so as to take an unbiased decision. After negotiation, a wage contract would be drawn up for each supervisor. This, he felt, would recognise and reward the better performers. Mr. Thakur successfully implemented the process for most of the supervisors, except those working in the night shift. For them he had drawn up the contracts unilaterally benchmarking the wages of supervisors of night shift with that of supervisors of the day shift.For several days Ram Lal a night shift supervisor, had been trying to seek an appointment with Mr. Thakur about his wages. He was disgruntled, not only over his failure to see the president, but also over the lack of discussions about his wage contract prior to its being effected. As a family man with six dependents, he felt his weekly wage should be higher than that granted to him.Last Thursday afternoon Ram Lal stopped by the president’s office and tried to see him.Mr. Thakur ’s secretary refused his request on the grounds that Mr. Thakur was busy.Infuriated, Ram Lal stormed into the president’s office and confronted the startled Mr.Thakur, with his demands for a better wage. Mr. Thakur stood up and told Ram Lal to get out of his office and express his grievance through official channel. Ram Lal took a swing at the president who in turn punched Ram Lal on the jaw and knocked him unconscious.Q.The most likely premise behind Mr. Thakur ’s initiative regarding individualised meetings with the supervisors seems to be

InstructionsComprehension:British colonial policy . . . went through two policy phases, or at least there were two strategies between which its policies actually oscillated, sometimes to its great advantage. At first, the new colonial apparatus exercised caution, and occupied India by a mix of military power and subtle diplomacy, the high ground in the middle of the circle of circles.This, however, pushed them into contradictions. For, whatever their sense of the strangeness of the country and the thinness of colonial presence, the British colonial state represented the great conquering discourse of Enlightenment rationalism, entering India precisely at the moment of its greatest unchecked arrogance. As inheritors and representatives of this discourse, which carried everything before it, this colonial state could hardly adopt for long such a self-denying attitude. It had restructured everything in Europe—the productive system, the political regimes, the moral and cognitive orders—and would do the same in India, particularly as some empirically inclined theorists of that generation considered the colonies a massive laboratory of utilitarian or other theoretical experiments. Consequently, the colonial state could not settle simply for eminence at the cost of its marginality; it began to take initiatives to introduce the logic of modernity into Indian society. But this modernity did not enter a passive society. Sometimes, its initiatives were resisted by pre-existing structural forms. At times, there was a more direct form of collective resistance. Therefore the map of continuity and discontinuity that this state left behind at the time of independence was rather complex and has to be traced with care.Most significantly, of course, initiatives for . . . modernity came to assume an external character. The acceptance of modernity came to be connected, ineradicably, with subjection. This again points to two different problems, one theoretical, the other political. Theoretically, because modernity was externally introduced, it is explanatorily unhelpful to apply the logical format of the ‘transition process’ to this pattern of change. Such a logical format would be wrong on two counts. First, however subtly, it would imply that what was proposed to be built was something like European capitalism. (And, in any case, historians have forcefully argued that what it was to replace was not like feudalism, with or without modificatory adjectives.) But, more fundamentally, the logical structure of endogenous change does not apply here.Here transformation agendas attack as an external force. This externality is not something that can be casually mentioned and forgotten. It is inscribed on every move, every object, every proposal, every legislative act, each line of causality. It comes to be marked on the epoch itself. This repetitive emphasis on externality should not be seen as a nationalist initiative that is so well rehearsed in Indian social science. . . .Quite apart from the externality of the entire historical proposal of modernity, some of its contents were remarkable. . . . Economic reforms, or rather alterations . . . did not foreshadow the construction of a classical capitalist economy, with its necessary emphasis on extractive and transport sectors.
