DIRECTIONS for the question 5:The year 2004 was a great year for Top-Cloth cotton mill. Manufacturing towels for the export market employing more than 2000 workers, the company had an impressive growth in sales and profits. The Chairman felt that employees were entitled to a share in the profits and it was proposed that the employee mess be air-conditioned. The proposal was discussed in a meeting that was attended by, among other senior officials, the marketing director, the personnel director and the finance director. The proposal was based on the fact that the shop floor of the mill often had temperatures in excess of 40°C with a relative humidity of 99%. The air-conditioned mess would represent management's appreciation of the employee's hard work.
At the end of 2005, management reviewed the mill's performance. Profits were higher, and employee attrition was negligible. Chairman decided that employees deserved additional recognition for their fine work. Since the mess had already been air-conditioned, the chairman wanted to know if the employees appreciated this sort of action. In the course of discussion, the chairman asked the personnel director to send a questionnaire to a sample of fifty employees and obtain their reaction to the air-conditioned mess. The management agreed to decide only after obtaining the feedback from the employees.
The personnel director mailed a simple form to fifty employees asked them for the following information: "Please state your reaction to the air-conditioned mess."
Of the fifty forms mailed, forty-six were returned. The answers received were as follows:
Reaction Frequency
"I did not know it was air-conditioned." 16
"I never eat there" 8
"If management can spend money like that, they should pay us more" 6
"I wish the entire mill was air-conditioned." 8
"The mess is for management employees." 4
"It is OK." 2

DIRECTIONS for questions 6 to 7: For each question, an answer (A) and a reason (R) has been given. Base your analysis on the information presented in the passage. Mark
The Society for Education in India (in short SEI) had been engaged in running primary schools in different parts of the country since 1950s. While attending a conference on employee selection, Mr. J Mehta, a senior member of the society learned that a leading school had recently employed a psychologist to perform employment functions, i.e. recruitment and selection of teachers. Within two months of his return, Mr. J Mehta contacted a reputed university and employed a graduating psychologist, Mr. Bibek Gupta. Mr. Bibek Gupta was employed by SEI with the single directive that he was to contribute to the selection of teachers. This task had previously been the prerogative of principals of each school. Mr. Gupta immediately notified each principal that in the future he was to be notified of the personnel needs and in return he would recruit, screen and select the teachers.
At the end of his first year with SEI, Mr. Gupta realized that his efforts had resulted in failure. During his first few months he encountered much opposition from several principals who had been managing schools for ten or more years. They did not believe in newer psychological techniques and preferred selecting people based on their own assessment. Other principals frequently refused to accept the teachers selected by Mr. Gupta. Finally, Mr. Gupta began to notice fewer and fewer principals notifying him of vacancies in their schools. Realizing that he was not making any effective contribution, Mr. Gupta submitted the suggestion to the society members that support and co-operation of the school principals should be a matter of executive order, or else his resignation should be considered.
  1. What was the flaw in the decision of selecting a psychologist for selecting teachers that led to the final situation?
    A: Mr. Mehta's decision was predominantly driven by the information about another school that had enlisted the services of a psychologist for recruitment and selection.
    R: Both the administration of the school and managing teachers have been primary responsibilities of the principal of the school.
    1. if both A and R are based on information given in the passage and R is the correct explanation of A.
    2. if both A and R are based on information given in the passage but R is not the correct explanation of A.
    3. if A is based on information given in the passage but R is not based on the facts given.
    4. if A is not based on information given in the passage but R is based on the information given in the passage.
    5. if both A and R are not based on information given in the passage.
  2. What responsibilities were shouldered by Mr. Bibek in his first year of employment?
    A: Mr. Bibek had the responsibility of contributing his expertise to recruitment and selection of teachers.
    R: The board members wanted to systematize the recruitment and selection of the entire organization.
    1. if both A and R are based on information given in the passage and R is the correct explanation of A.
    2. if both A and R are based on information given in the passage but R is not the correct explanation of A.
    3. if A is based on information given in the passage but R is not based on the facts given.
    4. if A is not based on information given in the passage but R is based on the information given in the passage.

Decision Making
1-4.  
Bill For Against
Recreation Bill Arjun, Bhim Karn
School Bill Karn / Bhim Arjun and Either Karn or Bhim
Tax Bill Karn / Arjun Bhim and Either Karn or Arjun
1. 5 We can modify the above table based on the additional information given in the question. Accordingly, Arjun and Bhim are the members who voted against the School Bill and Tax bill.

 

Bill For Against
Recreation Bill Arjun, Bhim Karn
School Bill Karn Arjun, Bhim
Tax Bill Karn Bhim, Arjun
By visual observation, it can be checked that Bhim votes against the school bill, thus option E is correct.
2. 1 We can modify the above table based on the additional information given in the question as follows:
Bill For Against
Recreation Bill Arjun, Bhim Karn
School Bill Bhim Arjun, Karn
Tax Bill Karn Bhim, Arjun
Thus, it can be verified that Arjun and Karn each vote for exactly one bill. The other answer choices do not follow from the above table. Hence, option A is correct. 
3. 3 We can modify the above table based on the additional information given in the question as follows:
Bill For Against
Recreation Bill Arjun, Bhim Karn
School Bill Karn Arjun, Bhim
Tax Bill Karn Bhim, Arjun

Thus, it can be observed that Karn votes for the school bill.                   

4. We can modify the above table based on the additional information given in the question as follows:
Bill For Against
Recreation Bill Arjun, Bhim Karn
School Bill Karn Arjun, Bhim
Tax Bill Karn Arjun, Bhim
Thus, Bhim votes for exactly one bill and hence option E is correct.
5. 1 The situation highlights the management’s short-sightedness.
6. 2 Both A and R are mentioned in the passage, but R is not the correct reason for A.
7. 3 A is mentioned in the passage while R is not.
8-11.  
Mobile Phone Digital Camera Music Player Office Document Viewer
T      
V χ
W  
X
Y χ χ
Z    
T may have any of three options.
Z may have Music Player and either Digital Camera or Office Document Viewer.
8. 3 It is clear from the table that it is possible to determine the option(s) of phones V, W, X and Y.
9. 1 Three or four mobile phones feature a music player.
10. 5 Z must have the music player and the office document viewer while T must have the digital camera. So only 3 models have the music player and option 5 is false.
11. 3 After assigning different features to the mobiles, it is seen that exactly four of the six mobiles have a document viewer. The best answer is option 3.
