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.

Question 191

# Which of the following represents the people sitting at extreme ends of both the lines?

Solution

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 at ends = G,E and in row-2 = X,Z

=> Ans - (C)
