Question Details

Directions (70-74): Study the following information carefully and answer the questions given below:

Eight persons A, B, C, D, E, F, G and H sit around a square table in such a way that four persons sit on each of the four corner of the table and other four persons sit on the middle of side. The one who sits at the corner of table faces inside and the one who sits at the middle side of table faces outwards the centre of table. Persons sitting on opposite sides are exactly opposite to each other.

B sits immediate left of A. Three persons sit between B and C. One person sits between H and C. F sits just left of H but not face outside. E sits 2nd to the left of G. D sits near G.

Solution :

To find out who sits exactly between D and B, let us analyze the given conditions step-by-step to determine the seating arrangement of the eight persons (A, B, C, D, E, F, G, and H) around the square table.

Step 1: Understand the seating rules
- Four persons sit at the corners and face inside (towards the center).
- Four persons sit at the middle of the sides and face outside (away from the center).
- Opposite sides are exactly opposite to each other.

Step 2: Analyze the clues
- "B sits immediate left of A."
- "Three persons sit between B and C." In a circle or square with 8 seats, three persons sitting between B and C means B and C are sitting exactly opposite to each other.
- "One person sits between H and C." This means H can be two seats away from C in either the clockwise or counter-clockwise direction.
- "F sits just left of H but not face outside." Since F does not face outside, F must face inside, which means F sits at one of the corners.
- "E sits 2nd to the left of G."
- "D sits near G" (meaning D is adjacent to G).

Step 3: Build the arrangement
Let us place A first. A can either sit at a corner or at the middle of a side.
Case 1: A sits at a corner (faces inside).
- B sits immediate left of A, so B must sit at the middle of the side to the immediate left of A (facing outside).
- C sits opposite to B (3 persons between B and C). Since B is at the middle of a side, C must be at the middle of the opposite side (facing outside).
- One person sits between H and C. Since C is at the middle of a side, the positions one seat away from C are corners. Thus, H must sit at a corner (facing inside). H can be either to the left or right of C.
- F sits just left of H and faces inside (corner). Since H sits at a corner (facing inside), H's immediate left is a middle-of-the-side position. If F sits there, F would face outside. But we are given that F does not face outside. Thus, Case 1 leads to a contradiction.

Case 2: A sits at the middle of a side (faces outside).
- B sits immediate left of A. Since A faces outside, A's left is to the right from an outside perspective. B must sit at the corner to the immediate left of A (facing inside).
- C sits opposite to B. Since B is at a corner, C must be at the opposite corner (facing inside).
- One person sits between H and C. The positions one seat away from C are middle-of-the-side positions. Thus, H must sit at a middle of a side (facing outside). H can be in one of two positions relative to C.
- F sits just left of H, and F does not face outside (so F faces inside, which means F sits at a corner). Since H faces outside, H's immediate left is to H's right (from the center's perspective), which is a corner position. Let us place H at the middle of the side adjacent to C such that F (corner) is to its immediate left. Specifically, if C is at the top-left corner, and H is at the top-middle side (facing outside), H's immediate left is the top-right corner. So F can sit at the top-right corner (facing inside). This is consistent.
- Now we have the remaining positions for E, G, and D.
- E sits 2nd to the left of G.
- D sits near G.
By placing G at the middle of the side, we find that G sits between D and B, satisfying all the conditions. Specifically, the order of persons sitting around the square table clockwise or counter-clockwise is determined as: A (middle), B (corner), G (middle), D (corner), C (corner), H (middle), F (corner), E (middle).
Looking at the arrangement, G sits at the middle position directly between the corner positions of D and B.

Therefore, the person who sits exactly between D and B is G.
