Family tree reasoning: Vinod is the brother of Bhaskar. Manohar is the sister of Vinod. Biswal is the brother of Preetam and Preetam is the daughter of Bhaskar. Who is the uncle of Biswal?

Introduction / Context:
The question presents a small kinship network: two siblings (Vinod and Bhaskar), another sibling (Manohar, female), and Bhaskar’s child Preetam with Preetam’s brother Biswal. We must identify Biswal’s uncle.

Given Data / Assumptions:

• Vinod and Bhaskar are brothers (both male).
• Manohar is the sister of Vinod (hence also sibling of Bhaskar, and female).
• Preetam is the daughter of Bhaskar (so Bhaskar is Preetam’s father).
• Biswal is Preetam’s brother (so Biswal is also Bhaskar’s child).

Concept / Approach:
“Uncle” of Biswal means the brother of one of Biswal’s parents (or husband of an aunt). We have Bhaskar explicitly as father. The brother of Biswal’s father is Vinod, which directly makes Vinod Biswal’s paternal uncle.

Step-by-Step Solution:
1) Parentage: Bhaskar → children: Preetam (daughter), Biswal (son).2) Siblings of Bhaskar: Vinod (brother), Manohar (sister).3) Uncle of Biswal = Bhaskar’s brother = Vinod.

Verification / Alternative check:
No other male sibling besides Vinod is named. An uncle by marriage (husband of Manohar) is not given; we avoid unsupported assumptions.

Why Other Options Are Wrong:

• Bhaskar: He is the father, not the uncle.
• Manohar: Female sibling → aunt, not uncle.
• Insufficient data: Data is sufficient to identify Vinod as the paternal uncle.

Common Pitfalls:
Confusing aunt/uncle based on gender or overcomplicating with missing spouses.

Final Answer:
Vinod
