Seating Arrangement Setup
The problem describes five people: Q, R, S, T, and U. They are sitting in a single row and all are facing the same direction, North. We are given specific placement clues relative to each other and need to find who is at the far left end of the row.
Analyzing the Clues for Placement
Let's break down the given information step-by-step:
- Neighbour Clue 1: "S is an immediate neighbour of both T and R." This tells us that S must be sitting directly between T and R. The sequence must look like either TSR or RST.
- Neighbour Clue 2: "R is an immediate neighbour of Q." This means R and Q are sitting next to each other. The sequence must be RQ or QR.
- Position Clue: "Q is at the extreme right end of the row." This is a fixed point. Since everyone faces North, the extreme right is the end position on the right side.
Determining the Final Arrangement
We can determine the seating order using the clues:
- Place Q: Q is at the extreme right end. Let's represent the row with 5 slots from left (1) to right (5). Q is in slot 5.
Row:
_ _ _ _ Q - Place R: R is next to Q. Since Q is at the end (slot 5), R must be in slot 4.
Row:
_ _ _ R Q - Place S and T: From Clue 1, S is between T and R. Since R is in slot 4, S must be in slot 3 to be next to R. T must then be next to S, placing T in slot 2. This forms the T-S-R sequence required.
Row:
_ T S R Q - Place U: Only one person (U) and one slot (slot 1, the extreme left) remain. U must therefore be in slot 1.
Final Row:
U T S R Q
The complete arrangement from left to right is U, T, S, R, Q.
Identifying the Leftmost Person
Looking at the final arrangement U T S R Q, the person occupying the first position (the extreme left end) is U.
Important Questions from Linear Arrangement
Eight friends, A, B, C, D, E, F, G and H, are sitting in two lines of four persons each. Both the lines are facing each other. A is facing D. E is to the immediate left of G. H is to the immediate right of B. C is facing G. F is facing H. B is to the immediate right of the person who is facing G. D is to the immediate left of F. Which four persons are sitting in the same line?
Nine employees, K, L, M, N, O, P, Q, R and S, are sitting in the office in a straight line, all facing the east. O is third to the right of M. K is third to the left of P. Q is between P and S. N is fourth to the right of M. P is to the immediate right of N. R is fourth to the left of O. Which of the following statements is NOT correct?
Eight north-facing restaurants named P, Q, R, S, T, U, V and W are located in a straight line. S is second to the left of T. W is third to the left of P. T is between P and V. S is third to the left of V. W is to the immediate right of U. R is third to the right of P. Who is sitting fourth to the right of S?
Anamika, Gopal, Nischal, Vanmayi, Shresta and Sripad are sitting in a straight line facing the north. Nischal is to the immediate left of Gopal. Shresta is between Anamika and Sripad. Sripad is at the second place from the right end. Four persons are sitting between Nischal and Vanmayi. If Gopal and Sripad interchange their positions, then who will be sitting between Vanmayi and Shresta?
A question is given, followed by two statements numbered (I) and (II). You have to decide whether the data provided in the statements is sufficient to answer the question. Read both the statements and select the appropriate answer.
Question: How many people are standing in the row where all people are facing north?
Statements:
(I) A is fourth from the left end; M is second to the right of A; and R is second from the left end.
(II) M is fourth from the right end; only two people Stand between M and B.
