Verified Answer
Eight persons in a family - Grandfather, Grandmother, Father, Mother, ...
One of the two couples (sitting diametrically opposite) is Mother-Father.
From (ii), Grandmother-Grandfather is not the couple sitting diametrically opposite.
Hence, the other couple sitting diametrically opposite must be one among “Son & Daughter-in-law” and “Daughter & Son-in-law*
From (ii), Grandmother-Grandfather is not the couple sitting diametrically opposite.
Hence, the other couple sitting diametrically opposite must be one among “Son & Daughter-in-law” and “Daughter & Son-in-law*
Case (I): Daughter and Son-in-law sit diametrically opposite.
Son-in-law is not beside Mother.
Case (II): Son and Daughter-in-law sit diametrically opposite.
The possible arrangements are:
OR
OR
It can be seen that Son-in-law never sits beside Mother.
Hence, option 4.

Most Upvoted Answer
Eight persons in a family - Grandfather, Grandmother, Father, Mother, ...
Given Information:
- Eight persons in a family: Grandfather, Grandmother, Father, Mother, Son, Daughter-in-law, Daughter, and Son-in-law.
- They are sitting in a circle, not necessarily in the same order.
- The chairs are arranged in perfect symmetry.
- Father and Mother are sitting farthest apart from each other.
- There are exactly two persons sitting between Grandfather and Grandmother.
- There is no person sitting between Mother and Daughter.
Analysis:
- Since the chairs are arranged in perfect symmetry, it means that the family members are evenly spaced around the circle.
- From the given information, we can deduce a few possibilities:
- If Father and Mother are sitting farthest apart, then they must be diametrically opposite each other.
- Since there are exactly two persons sitting between Grandfather and Grandmother, they can either be sitting next to each other or have one person sitting between them.
- Since there is no person sitting between Mother and Daughter, they must either be sitting next to each other or have one person sitting between them.
Possible Arrangements:
Let's consider the possible arrangements based on the given information:
1. Father and Mother are diametrically opposite:
- Grandfather and Grandmother must have two persons sitting between them.
- Mother and Daughter must be sitting next to each other.
- The remaining three family members (Son, Daughter-in-law, and Son-in-law) can be seated in any order as long as the conditions are met.
2. Grandfather and Grandmother have two persons sitting between them:
- Father and Mother cannot be sitting diametrically opposite each other because that would violate the condition that Grandfather and Grandmother have two persons between them.
- In this case, there must be one person between Grandfather and Grandmother, and they cannot be sitting next to each other.
- Mother and Daughter must be sitting next to each other.
- The remaining three family members (Father, Son-in-law, and Daughter-in-law) can be seated in any order as long as the conditions are met.
In both possible arrangements, Mother and Daughter are sitting next to each other. Therefore, the person who cannot be sitting beside Mother if exactly two couples are sitting diametrically opposite is Son-in-law.
- Eight persons in a family: Grandfather, Grandmother, Father, Mother, Son, Daughter-in-law, Daughter, and Son-in-law.
- They are sitting in a circle, not necessarily in the same order.
- The chairs are arranged in perfect symmetry.
- Father and Mother are sitting farthest apart from each other.
- There are exactly two persons sitting between Grandfather and Grandmother.
- There is no person sitting between Mother and Daughter.

- Since there are exactly two persons sitting between Grandfather and Grandmother, they can either be sitting next to each other or have one person sitting between them.
- Since there is no person sitting between Mother and Daughter, they must either be sitting next to each other or have one person sitting between them.

1. Father and Mother are diametrically opposite:
- Grandfather and Grandmother must have two persons sitting between them.
- Mother and Daughter must be sitting next to each other.
- The remaining three family members (Son, Daughter-in-law, and Son-in-law) can be seated in any order as long as the conditions are met.
2. Grandfather and Grandmother have two persons sitting between them:
- Father and Mother cannot be sitting diametrically opposite each other because that would violate the condition that Grandfather and Grandmother have two persons between them.
- In this case, there must be one person between Grandfather and Grandmother, and they cannot be sitting next to each other.
- Mother and Daughter must be sitting next to each other.
- The remaining three family members (Father, Son-in-law, and Daughter-in-law) can be seated in any order as long as the conditions are met.
In both possible arrangements, Mother and Daughter are sitting next to each other. Therefore, the person who cannot be sitting beside Mother if exactly two couples are sitting diametrically opposite is Son-in-law.
