Question 1 of 10
1. Question
Directions: Read the information given below and answer the questions.
Eight students – P, Q, R, S, T, U, V and W are sitting in a row. Four of them are facing north and four of them are facing south. Each of them has roll number among 5, 20, 16, 12, 14, 9, 8 and 2, not necessarily in the same order.
Further information is given as:
 a) P and V are sitting adjacent to each other and facing different directions.
 b) R, whose roll number is14, sits 5^{th} to the right of the person whose roll number is 16.
 c) U and the person whose roll number is 9, sit adjacent to each other and face south.
 d) V’s roll number is 20 and sits adjacent to Q, whose roll number is 16.
 e) Exactly three people sit between P and W.
 f) The person whose roll number is 8, is an immediate neighbor of persons, whose roll numbers are 14 and 2.
 g) Person whose roll number is 12 does not face north.
 h) All the people facing north are sitting together. Similarly, all the people facing south are also sitting together.
What is the roll number of the person sitting to the immediate left of P?
Correct
P and V are sitting adjacent to each other and facing different directions. All the people facing north are sitting together. Similarly, all the people facing south are also sitting together. So, V may sit at position 4 or 5. If V sits at position 4, then P sits at position 5 and if V sits at position 5, then P sits at position 4 and both of them face in opposite direction. V’s roll number is 20 and sits adjacent to Q whose roll number is16. So, Q may sit at position 3 or 6 according to the position of V. R, whose roll number is 14, sits 5^{th} to the right of the person whoseroll number is16 and faces south. So, two cases are possible.
Case I:
V sits at position 4 and faces north and P sits at position 5 and faces south. Q sits at position 3 and faces north and has roll number16. So, R sits at position 8 and has roll number 14. The person whose roll number is8 is an immediate neighbor of persons whose roll numbers are 14 and 2. So, the one whose roll number is8 sit at position 7 and the one whoseroll number is2sit at position 6. Exactly three people sit between P and W. So, W sits at position 1. U and the person whose roll number is 9 sit adjacent to each other and face south, if P’s roll number is 9 then U sits at 6. But there is no seat for the student whose roll number is 12.
Hence, this case is rejected.
Case II:
V sits at position 5 and faces south and P sits at position 4 and faces north. Q sits at position 6 and faces south and has roll number 16. So, R sits at position 1 and has roll number 14 and faces north. The person whose roll number is 8 is an immediate neighbor of persons who has roll numbers are 14 and 2. So, the one whose roll number is 8 sits at position 2 and the one whose roll number is 2 sits at position 3. Exactly three people sit between P and W. So, W sits at position 8. U and the person whose roll number is 9 sit adjacent to each other and face south. So, U sits at position 7 and W’s roll number is 9. Person whose roll number is 12 does not face north. So, U’s roll number is 12. So, P’s roll number is 5. S and T sit at position 2 and 3 but not necessarily in same order.
So, the final arrangement is:
Direction North North North North South South South South Person 1. R 2. S/T 3. T/S 4. P 5. V 6. Q 7. U 8. W Roll number 14 8 2 5 20 16 12 9 The person sitting to the immediate left of P has roll number 2.
Hence, option d.
Incorrect
P and V are sitting adjacent to each other and facing different directions. All the people facing north are sitting together. Similarly, all the people facing south are also sitting together. So, V may sit at position 4 or 5. If V sits at position 4, then P sits at position 5 and if V sits at position 5, then P sits at position 4 and both of them face in opposite direction. V’s roll number is 20 and sits adjacent to Q whose roll number is16. So, Q may sit at position 3 or 6 according to the position of V. R, whose roll number is 14, sits 5^{th} to the right of the person whoseroll number is16 and faces south. So, two cases are possible.
Case I:
V sits at position 4 and faces north and P sits at position 5 and faces south. Q sits at position 3 and faces north and has roll number16. So, R sits at position 8 and has roll number 14. The person whose roll number is8 is an immediate neighbor of persons whose roll numbers are 14 and 2. So, the one whose roll number is8 sit at position 7 and the one whoseroll number is2sit at position 6. Exactly three people sit between P and W. So, W sits at position 1. U and the person whose roll number is 9 sit adjacent to each other and face south, if P’s roll number is 9 then U sits at 6. But there is no seat for the student whose roll number is 12.
Hence, this case is rejected.
Case II:
V sits at position 5 and faces south and P sits at position 4 and faces north. Q sits at position 6 and faces south and has roll number 16. So, R sits at position 1 and has roll number 14 and faces north. The person whose roll number is 8 is an immediate neighbor of persons who has roll numbers are 14 and 2. So, the one whose roll number is 8 sits at position 2 and the one whose roll number is 2 sits at position 3. Exactly three people sit between P and W. So, W sits at position 8. U and the person whose roll number is 9 sit adjacent to each other and face south. So, U sits at position 7 and W’s roll number is 9. Person whose roll number is 12 does not face north. So, U’s roll number is 12. So, P’s roll number is 5. S and T sit at position 2 and 3 but not necessarily in same order.
So, the final arrangement is:
Direction North North North North South South South South Person 1. R 2. S/T 3. T/S 4. P 5. V 6. Q 7. U 8. W Roll number 14 8 2 5 20 16 12 9 The person sitting to the immediate left of P has roll number 2.
Hence, option d.

So, R sits at position 1 and has roll number 14 and faces north. The person whose roll number is 8 is an immediate neighbor of persons who has roll numbers are 14 and 2. So, the one whose roll number is 8 sits at position 2 and the one whose roll number is 2 sits at position 3. Exactly three people sit between P and W. So, W sits at position 8. U and the person whose roll number is 9 sit adjacent to each other and face south. So, U sits at position 7 and W’s roll number is 9. Person whose roll number is 12 does not face north. So, U’s roll number is 12. So, P’s roll number is 5. S and T sit at position 2 and 3 but not necessarily in same order.
So, the final arrangement is:
Direction North North North North South South South South Person 1. R 2. S/T 3. T/S 4. P 5. V 6. Q 7. U 8. W Roll number 14 8 2 5 20 16 12 9 P sits third to the right of the person whose roll number is 12.
Hence, option a.
Incorrect
P and V are sitting adjacent to each other and facing different directions. All the people facing north are sitting together. Similarly, all the people facing south are also sitting together. So, V may sit at position 4 or 5. If V sits at position 4, then P sits at position 5 and if V sits at position 5, then P sits at position 4 and both of them face in opposite direction. V’s roll number is 20 and sits adjacent to Q whose roll number is16. So, Q may sit at position 3 or 6 according to the position of V. R, whose roll number is 14, sits 5^{th} to the right of the person whoseroll number is16 and faces south. So, two cases are possible.
Case I:
V sits at position 4 and faces north and P sits at position 5 and faces south. Q sits at position 3 and faces north and has roll number16. So, R sits at position 8 and has roll number 14. The person whose roll number is8 is an immediate neighbor of persons whose roll numbers are 14 and 2. So, the one whose roll number is8 sit at position 7 and the one whoseroll number is2sit at position 6. Exactly three people sit between P and W. So, W sits at position 1. U and the person whose roll number is 9 sit adjacent to each other and face south, if P’s roll number is 9 then U sits at 6. But there is no seat for the student whose roll number is 12.
Hence, this case is rejected.
Case II:
V sits at position 5 and faces south and P sits at position 4 and faces north. Q sits at position 6 and faces south and has roll number 16. So, R sits at position 1 and has roll number 14 and faces north. The person whose roll number is 8 is an immediate neighbor of persons who has roll numbers are 14 and 2. So, the one whose roll number is 8 sits at position 2 and the one whose roll number is 2 sits at position 3. Exactly three people sit between P and W. So, W sits at position 8. U and the person whose roll number is 9 sit adjacent to each other and face south. So, U sits at position 7 and W’s roll number is 9. Person whose roll number is 12 does not face north. So, U’s roll number is 12. So, P’s roll number is 5. S and T sit at position 2 and 3 but not necessarily in same order.
So, the final arrangement is:
Direction North North North North South South South South Person 1. R 2. S/T 3. T/S 4. P 5. V 6. Q 7. U 8. W Roll number 14 8 2 5 20 16 12 9 P sits third to the right of the person whose roll number is 12.
Hence, option a.

6. Question
Directions: Read the following information and answer the questions.
There are 6 persons A, B, C, D, E and F, who are doing Ph.D. from different colleges amongNSIT, St. Stephens, DTU, Miranda, IITD and IIITD (not necessarily in the same order). They have published different number of papers ranging from 2 to 8in multiples of 2(not necessarily in the same order). They are already placed in different companies among TCS, Google, IBM, Infosys, Wipro and NIIT (not necessarily in order). Not more than two persons published same number of papers.
A is placed in IITD. C is placed in Infosys. D is doing Ph.D. from NSIT. A has published either 6 or 8papers and no other person has published same number of papers as that of A. The one who is placed in Google has published 6 papers and he is the only one having 6papers. The one, who is doing Ph.D. from Miranda, has published lower number of papers than C. B is not doing Ph.D. from Miranda. The number of papers published by E and C is same. The person placed in IBM has published 4papers. The person who is doing Ph.D. from Miranda and B are not placed in IBM. Neither E nor C is in St. Stephens. D and B have not published same number of papers. The person in St. Stephens has not published 2 papers. The one placed in Infosys is not doing Ph.D. from DTU. The one placed in TCS has not published 2 papers. B is not placed in TCS. F isn’t placed in Wipro. C has not published 8papers.
Who is placed in NIIT?
Correct
A is in IITD. C is placed in Infosys. D is in NSIT. A has published either 6 or 8papers and no other person has same number of papers as A. There can be two cases:
Case 1: A has published 6 papers. The one who is placed in Google has published 6papers and he is the only one, who published 6papers. A is placed in Google and is the only one, who has published 6papers. The one in Miranda college has published lower number of papers than C. B is not in Miranda. The number of papers published by E and C is same. Only F can be in Miranda. Neither E nor C is in St. Stephens. B is in St. Stephens. E and C have published 4 or 8papers but C has not published 8papers so E and C have published 4papers. The person placed in IBM has published 4papers. The one in Miranda and B are not placed in IBM. F must have published 2papers. Only E is placed in IBM. Since the one, in St. Stephens has not published 2papers, he must have published 8papers. D must have published 2papers since D and B have not published the same number of papers. The one placed in TCS has not published 2papers. B is placed in TCS but this conclusion is contradictory so this case gets rejected.
Case 2: A has published 8papers. The one in Miranda has published lower number of papers than C. B is not in Miranda. The number of papers published by E and C is same. E and C must have published 4 papers. The person placed in IBM has published 4papers. E is placed in IBM. It also implies that only F is in Miranda and he must have published 2papers. As neither E nor C is in St. Stephens and the one in St. Stephens has not published 2 papers, only B can be in St. Stephens and he has published 6papers and thus, he must be placed in Google. It implies that D has published 2papers. The one placed in TCS has not published 2papers. A is placed in TCS. F is not placed in Wipro. F is placed in NIIT and D is placed in Wipro. The one, who is placed in Infosys, is not in DTU. E is in DTU and C is in IIITD.
