Introduction / Context:
This circular arrangement question asks you to place six family members around a table based on relative-position clues and then determine who is directly opposite a specified person. Such problems test spatial reasoning and your ability to combine multiple relational statements consistently.
Given Data / Assumptions:
- Members: Pankaj (P), Gopi (G), Chetan (C), Dinesh (D), Akash (A) and Vyom (V).
- All stand around a circular table facing the centre.
- Gopi is between Vyom and Chetan (so G's neighbours are V and C in some order).
- Pankaj is between Akash and Dinesh (P's neighbours are A and D in some order).
- Vyom is immediately to the right of Dinesh.
- We must find who stands directly opposite Dinesh.
Concept / Approach:
In a circle of six people, sitting opposite means being exactly three positions away. We use the “immediately to the right” information to fix a base orientation, then place the remaining members using the “between” conditions without violating the circular ordering.
Step-by-Step Solution:
Step 1: Place Dinesh at some reference position in the circle. Since everyone faces the centre, we can place D at the top for convenience.
Step 2: Vyom is immediately to the right of Dinesh. Facing the centre, the right side is clockwise. So place V immediately clockwise next to D.
Step 3: Gopi is between Vyom and Chetan. That means G must have V on one side and C on the other. Since V already has D on its left (counter-clockwise) and an empty seat on its right (clockwise), the only way for G to be between V and C is to place G on the other side of V, and then place C next to G.
Step 4: This gives a partial clockwise order: D → V → G → C.
Step 5: Now consider Pankaj's condition: Pankaj is between Akash and Dinesh. So P must have A and D as his immediate neighbours.
Step 6: Around D there are two neighbouring positions: one already occupied by V and one unoccupied on the other side. For P to be between A and D, P must occupy the remaining neighbour seat of D, and A must then be adjacent to P on the opposite side.
Step 7: This completes the circle in clockwise order as A → P → D → V → G → C → back to A.
Step 8: In a circle of six, the person directly opposite D is three positions away. Counting three steps clockwise from D: D(0), V(1), G(2), C(3). Thus, Chetan is directly opposite Dinesh.
Verification / Alternative check:
We can also count counter-clockwise: from D to P (1), to A (2), to C (3). We again reach Chetan as the member opposite Dinesh. Both directions give the same result, confirming the arrangement is consistent and unique under the given constraints.
Why Other Options Are Wrong:
Pankaj: He sits adjacent to Dinesh, not opposite.
Vyom: He is immediately to the right of Dinesh, again adjacent but not opposite.
Gopi: Gopi is two positions away from D in either direction, not three.
Akash: Akash sits next to Pankaj and is two steps away from D, so cannot be opposite.
Common Pitfalls:
A common mistake is reversing left and right when everyone faces the centre, or placing the “between” persons incorrectly with more than one person on each side. Drawing a simple labelled circle and placing members step by step greatly reduces confusion and prevents misinterpretations of “between” and “immediately to the right”.
Final Answer:
Therefore, the family member standing opposite Dinesh is
Chetan.
