Instructions

Study the following information carefully and answer the questions given below:
Eight persons — E, F, G, H, W, X, Y and Z — are sitting in two parallel rows containing four persons each. E. F, G and H are sitting in row-1 facing north and W. X, Y and Z are sitting in row-2 facing south (but not necessarily in the same order.) Thus, each person sitting in row – 1 faces another person sitting in row – 2, Each of the two rows consists of one Doctor, one Engineer, one Pilot and one Scientist (but not necessarily in the same order).

• The Doctor of row-1 sits second to the right of H. X faces one of the immediate neighbours of H. Only one person sits between the X and the Scientist.
• The one who faces the Scientist of row – 2 is an immediate neighbour of E. Only one person sits between E and the Pilot.
• W sits second to the right of Z. Y does not face G. The Scientist of row-1 faces the Engineer of row – 2.
• G faces one of the immediate neighbours of the Doctor of row-2. The Doctor of row-2 does not sit at any of the extreme ends of the line. Z is not a Doctor.

Q1: If Y and X interchange their places, so do H and Z, then who amongst the following will face E?
(a) Y 
(b) H 
(c) F 
(d) W
Ans: (b)
Sol: In row-1, E,F,G & H are sitting facing north while W,X,Y & Z are sitting in row-2 facing south.
The Doctor of row-1 sits second to the right of H.
Case 1: H sits at extreme left end of row 1.
Also, X faces one of the immediate neighbours of H, => X sits opposite to the person who is immediate right of H and Scientist in row -2 sits at extreme left end.
Now, The one who faces the Scientist of row – 2 is an immediate neighbour of E, => E is doctor in row-1 and H is the pilot.
W sits second to the right of Z, => W sits at extreme right end of row-2 and Z to the immediate left of X. Only position left in row-2 is extreme left end, which is now filled by Y being the scientist. The arrangement is:

But doctor of row(II) does not sit at end and Z is also not the doctor. Thus, this case is not possible.
Case 2: H sits at second from left end of row-1, => Doctor sits at extreme right end in this row.
Also, X faces one of the immediate neighbours of H, => X sits at extreme right end of row-2 and the scientist sits second to the left of X.
Now, The one who faces the Scientist of row – 2 is an immediate neighbour of E, => E is doctor in row-1 sitting at extreme right and H is the pilot.
W sits second to the right of Z, => W sits to the immediate left of X and Z to the extreme left end of row-2. Only position left in row-2 is occupied by Y being the scientist.
Since, Y and G does not sit opposite to each other, => G sits at extreme left end of row-1.
The arrangement is:

Currently, Z is facing E, if Z and H interchange their positions, then H will face E.

Q2: Which of the following represent both the immediate neighbours of Y?
(a) Z and the Scientist of row-2
(b) X and the Engineer of row-2
(c) W and the Doctor of row-2
(d) W and the Pilot of row-2
Ans: (d)
Sol: In row-1, E,F,G & H are sitting facing north while W,X,Y & Z are sitting in row-2 facing south.
The Doctor of row-1 sits second to the right of H.
Case 1: H sits at extreme left end of row 1.
Also, X faces one of the immediate neighbours of H, => X sits opposite to the person who is immediate right of H and Scientist in row -2 sits at extreme left end.
Now, The one who faces the Scientist of row – 2 is an immediate neighbour of E, => E is doctor in row-1 and H is the pilot.
W sits second to the right of Z, => W sits at extreme right end of row-2 and Z to the immediate left of X. Only position left in row-2 is extreme left end, which is now filled by Y being the scientist. The arrangement is:

But doctor of row(II) does not sit at end and Z is also not the doctor. Thus, this case is not possible.
Case 2: H sits at second from left end of row-1, => Doctor sits at extreme right end in this row.
Also, X faces one of the immediate neighbours of H, => X sits at extreme right end of row-2 and the scientist sits second to the left of X.
Now, The one who faces the Scientist of row – 2 is an immediate neighbour of E, => E is doctor in row-1 sitting at extreme right and H is the pilot.
W sits second to the right of Z, => W sits to the immediate left of X and Z to the extreme left end of row-2. Only position left in row-2 is occupied by Y being the scientist.
Since, Y and G does not sit opposite to each other, => G sits at extreme left end of row-1.
The arrangement is:

The immediate neighbors of Y are = W (doctor) and Z (pilot).

Q3: Who amongst the following sits to the immediate left of Pilot of row-1?
(a) H
(b) The Doctor of row-1
(c) The Engineer of row – 1
(d) G
Ans: (d)
Sol: In row-1, E,F,G & H are sitting facing north while W,X,Y & Z are sitting in row-2 facing south.
The Doctor of row-1 sits second to the right of H.
Case 1: H sits at extreme left end of row 1.
Also, X faces one of the immediate neighbours of H, => X sits opposite to the person who is immediate right of H and Scientist in row -2 sits at extreme left end.
Now, The one who faces the Scientist of row – 2 is an immediate neighbour of E, => E is doctor in row-1 and H is the pilot.
W sits second to the right of Z, => W sits at extreme right end of row-2 and Z to the immediate left of X. Only position left in row-2 is extreme left end, which is now filled by Y being the scientist. The arrangement is:

But doctor of row(II) does not sit at end and Z is also not the doctor. Thus, this case is not possible.
Case 2: H sits at second from left end of row-1, => Doctor sits at extreme right end in this row.
Also, X faces one of the immediate neighbours of H, => X sits at extreme right end of row-2 and the scientist sits second to the left of X.
Now, The one who faces the Scientist of row – 2 is an immediate neighbour of E, => E is doctor in row-1 sitting at extreme right and H is the pilot.
W sits second to the right of Z, => W sits to the immediate left of X and Z to the extreme left end of row-2. Only position left in row-2 is occupied by Y being the scientist.
Since, Y and G does not sit opposite to each other, => G sits at extreme left end of row-1.
The arrangement is:

In row-1, the person who is sitting to the immediate left of H (pilot) = G (scientist)
