The questions below are based on the following information :

Two union representatives and one management representative are seated together at an octagonal table with one seat to a side of the table. No person of either union or management representatives may be seated together. Two additional management representatives are seated.

Study the following information carefully to answer the question that follows.

At an Electronic Data Processing Unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day.
The program operating must also satisfy the following conditions :
(I). If program P is to be operated on a day, V cannot be operated on that day.
(II). If Q is to be operated on a day. T must be one of the programs to be operated after Q.
(III). If R is to be operated on a day. V must be one of the programs to be operated after R.
(IV). The last program to be operated on any day must be either S or U.

Q. No. 1:	Which of the following could be the set of programs to be operated on the first day of a month ?
A :	U,Q,S,T,W
B :	V,Q,R,T,S
C :	T,U,R,V,S
D :	Q,S,R,V,U
Solution Answer: C The last program to be operated on any day must be either S or U. So, option (A) is ruled out. Similarly for B and D.

Q. No. 2:	Which of the following is true of any day's valid program set operation ?
A :	Q cannot be operated at the third place.
B :	P cannot be operated at the third place.
C :	R cannot be operated at the fourth place.
D :	T cannot be operated at the third place.
Solution Answer: C If R is operated at forth place , V must be operated at fifth place which negates the condition (IV).

Q. No. 3:	If R is operated at third place then in a sequence, which of the following cannot be second program in that sequence ?
A :	S
B :	Q
C :	T
D :	U
Solution Answer: B Q cannot be operated at second place when R is operated at third place because "I" must be operated after that which is not possible.

Read the following information carefully and answer the questions given below it :

The six chapters in a printed textbook are inadvertently bound together in the wrong order by a book binder. As a result of error, the following situation exists.
(i). Any two chapters, which ordinarily would be adjacent, are no longer so.
(ii). Exactly one of the chapters is currently occupying is current position in the text.
(iii). Chapter 1 occurs after chapter 6 and exactly one other chapter separates them.
(iv). Chapter 4 is not last.
(v). Chapter 5 occurs before chapter 2.

Q. No. 1:	Which of the following must be false ?
A :	Chapter 3 comes before chapter 2
B :	Chapter 3 comes before chapter 4
C :	Chapter 5 comes before chapter 1
D :	Chapter 3 occurs last
Solution Answer: D Following the conditions given in the questions , we can make following possible order: i). 463152 ii). 364152 iii). 526413 iv). 524631 All the four arrangements follow all the conditions except one that exactly one of the chapters is currently occupying in correct position in the text. In Arrangement (i)- Two chapters 3 and 5 occupy their correct positions and hence, is an invalid argument. In Arrangement (ii) - Only chapter 5 occupies its correct position and hence, is a valid argument. In Arrangement (iii) - Chapter 2 and 4 occupy the correct positions and hence, is an invalid argument. In Arrangement (iv) - Only chapter 2 occupies its correct position and hence, is a valid order. Therefore, we obtain final two possible orders as : i). 364152 ii). 524631 * It is clear from the above two statements that option d , the chapter 3 occur last, is definitely false.

Q. No. 2:	Which chapter cannot occur among the last 3 chapters ?
A :	1
B :	5
C :	6
D :	4
Solution Answer: D Following the conditions given in the questions , we can make following possible order: i). 463152 ii). 364152 iii). 526413 iv). 524631 All the four arrangements follow all the conditions except one that exactly one of the chapters is currently occupying in correct position in the text. In Arrangement (i)- Two chapters 3 and 5 occupy their correct positions and hence, is an invalid argument. In Arrangement (ii) - Only chapter 5 occupies its correct position and hence, is a valid argument. In Arrangement (iii) - Chapter 2 and 4 occupy the correct positions and hence, is an invalid argument. In Arrangement (iv) - Only chapter 2 occupies its correct position and hence, is a valid order. Therefore, we obtain final two possible orders as : i). 364152 ii). 52463

Q. No. 3:	Which chapter might be in their original position ?
A :	3 and 4
B :	4 and 5
C :	2 and 5
D :	3 and 5
Solution Answer: C Following the conditions given in the questions , we can make following possible order: i). 463152 ii). 364152 iii). 526413 iv). 524631 All the four arrangements follow all the conditions except one that exactly one of the chapters is currently occupying in correct position in the text. In Arrangement (i)- Two chapters 3 and 5 occupy their correct positions and hence, is an invalid argument. In Arrangement (ii) - Only chapter 5 occupies its correct position and hence, is a valid argument. In Arrangement (iii) - Chapter 2 and 4 occupy the correct positions and hence, is an invalid argument. In Arrangement (iv) - Only chapter 2 occupies its correct position and hence, is a valid order. Therefore, we obtain final two possible orders as : i). 364152 ii). 524631 *From two order it is clear that in arrangement (i), chapter 5 is in its correct position and in arrangement (ii), chapter 2 is in correct position.

Q. No. 4:	Which of the following could possibly be TRUE? I). Chapter 6 comes after chapter 2. II). Chapter 4 comes after chapter 5 III). Chapter 6 comes after chapter 4.
A :	Only I and III
B :	Only I and II
C :	Only II and III
D :	All three
Solution Answer: D Following the conditions given in the questions , we can make following possible order: i). 463152 ii). 364152 iii). 526413 iv). 524631 All the four arrangements follow all the conditions except one that exactly one of the chapters is currently occupying in correct position in the text. In Arrangement (i)- Two chapters 3 and 5 occupy their correct positions and hence, is an invalid argument. In Arrangement (ii) - Only chapter 5 occupies its correct position and hence, is a valid argument. In Arrangement (iii) - Chapter 2 and 4 occupy the correct positions and hence, is an invalid argument. In Arrangement (iv) - Only chapter 2 occupies its correct position and hence, is a valid order. Therefore, we obtain final two possible orders as : i). 364152 ii). 524631
