Daya has a brother named Anil. Daya is the son of Chandra, and Bimal is the father of Chandra. In terms of relationship, who is Anil to Bimal?

Introduction / Context:
This question checks basic understanding of three generation family trees. You are given a person, that person's parent and that parent's parent, and you must correctly trace how a sibling fits into the picture. These questions are easy if you draw a quick diagram or imagine a simple family tree.

Given Data / Assumptions:

• Daya and Anil are brothers, so they share at least one parent.
• Daya is the son of Chandra, so Chandra is a parent of Daya.
• Bimal is the father of Chandra, so Bimal is one generation above Chandra.
• We assume that Anil is also a child of Chandra, since he is the brother of Daya.

Concept / Approach:
To find who Anil is to Bimal, first fix the generations. Bimal is the oldest generation here, Chandra is the next generation, and Daya and Anil form the youngest generation. A person in the youngest generation whose parent is the child of Bimal will be a grandchild of Bimal. Since Daya is explicitly described as the son of Chandra and Anil is his brother, Anil also fits into the same generation and parental link.

Step-by-Step Solution:
Step 1: Note that Bimal is the father of Chandra, so Chandra is Bimal's child.Step 2: Daya is described as the son of Chandra, so Daya is Bimal's grandson.Step 3: Daya and Anil are brothers, so they share the same parent Chandra.Step 4: Since Anil is also a child of Chandra, he is another grandchild of Bimal.Step 5: Therefore, Anil is the grandson of Bimal.

Verification / Alternative check:
Draw a small family tree. Put Bimal at the top. Under Bimal, write Chandra. Under Chandra, write Daya and Anil as siblings. The relationship between the top generation and the bottom generation is always grandparent to grandchild. Nothing in the problem suggests adoption or step relationships, so the straightforward interpretation is correct.

Why Other Options Are Wrong:
Son is wrong because Chandra, not Anil, is the direct child of Bimal.Brother is wrong since Bimal is one generation above Anil, not his sibling.Grandfather is the relation of Bimal to Anil, not the other way around.Cousin requires two separate sibling branches, which the data does not introduce.

Common Pitfalls:
Students sometimes stop too early and say that Anil is a son of Chandra and hence wrongly guess son of Bimal. Always count the number of steps on the family tree. From Anil up to Bimal there are two steps: Anil to Chandra, and Chandra to Bimal. Two steps up from a person leads to a grandparent, so the person is a grandchild.

Final Answer:
In terms of relationship, Anil is the Grandson of Bimal.
