Sandeep has a brother named Ankur. Sandeep is the son of Kishan, and Baljor is Kishan's father. How is Ankur related to Baljor?

Introduction / Context:
This question mirrors a standard three-generation family structure. You have a grandfather (Baljor), his son (Kishan) and Kishan's sons (Sandeep and Ankur). The task is to identify the relationship between Ankur and Baljor. It is a simple generational reasoning question designed to reinforce the concept of grandchildren.

Given Data / Assumptions:
- Sandeep has a brother called Ankur. - Sandeep is the son of Kishan. - Baljor is Kishan's father. - All relationships follow a basic father–son pattern.

Concept / Approach:
Kishan is the son of Baljor, and Ankur is a son of Kishan (because he is Sandeep's brother and Sandeep is Kishan's son). A person who is the child of your child is your grandchild. Therefore, Ankur is the grandson of Baljor. We just need to confirm that there is no reason to choose father, brother or son instead.

Step-by-Step Solution:
Step 1: Recognise that Kishan is directly described as the son of Baljor. Step 2: Sandeep is given as the son of Kishan, which makes Sandeep a grandson of Baljor. Step 3: Ankur is the brother of Sandeep, so Ankur shares the same parents as Sandeep in this typical context. Step 4: Therefore, Ankur is also a son of Kishan. Step 5: Since Ankur is Kishan's son and Kishan is Baljor's son, Ankur is a grandson of Baljor.

Verification / Alternative check:
Create a simple diagram: put Baljor at the top, Kishan below him as his son, and Sandeep and Ankur below Kishan as siblings. Both Sandeep and Ankur are two generations below Baljor. This generational distance indicates they are grandchildren, not children, brothers or uncles. Thus, Ankur is unambiguously a grandson of Baljor.

Why Other Options Are Wrong:
- Brother: A brother of Baljor would share parents with him, which is not indicated here. - Son: Kishan is clearly the son of Baljor; Ankur is one generation further down. - Grandfather: A grandfather would be one generation above, but Ankur is two generations below Baljor, not above. - Uncle: An uncle is a sibling of a parent. Ankur is the child of Kishan, not the sibling of Kishan.

Common Pitfalls:
Because the question states Sandeep has a brother named Ankur, some examinees focus on the relationship between the two brothers and forget to track the generations up to Baljor. Another pitfall is to confuse whose father is whose and mistakenly call Ankur a son instead of a grandson. Always check how many steps of parenthood separate two people; here, there are two steps (Baljor → Kishan → Ankur), which defines the grandparent–grandchild relationship.

Final Answer:
Ankur is Baljor's grandson.
