Solving the Family Relationship Puzzle

This question asks us to determine the relationship between two individuals, Krish and Suresh, based on a series of stated family connections. To solve this, we need to carefully trace the relationships step-by-step.

Analyzing the Given Relationships

Let's break down the information provided:

  • Bharat and Sapna are husband and wife.
  • Rohit and Bharat are brothers.
  • Suresh is the father of Rohit.
  • Sapna’s son is Krish.

Step-by-Step Deduction

Now, let's use the given information to connect Krish and Suresh:

  1. We are told Rohit and Bharat are brothers.
  2. We are told Suresh is the father of Rohit. Since Rohit and Bharat are brothers, Suresh is also the father of Bharat. So, Suresh is Bharat’s father.
  3. We are told Sapna’s son is Krish. Since Bharat and Sapna are husband and wife, and Krish is Sapna’s son, Krish is also Bharat’s son. So, Bharat is Krish’s father.

Connecting Krish and Suresh

We have established two key connections:

  • Suresh is the father of Bharat.
  • Bharat is the father of Krish.

If Suresh is the father of Bharat, and Bharat is the father of Krish, then Krish is the son of Suresh's son. A person who is the son of one's son is called a grandson.

Therefore, Krish is the grandson of Suresh.

Verification with Options

Let's check our deduced relationship against the given options:

  • Son: Incorrect. Suresh is the father of Bharat, not Krish.
  • Uncle: Incorrect. An uncle is a sibling of one's parent. Suresh is the grandfather, not an uncle.
  • Grandson: Correct. Krish is the son of Bharat, who is the son of Suresh.
  • Father: Incorrect. Suresh is the father of Rohit and Bharat, not Krish.

The relationship between Krish and Suresh is grandson.

Additional Information on Family Relationship Logic

Family relationship questions test your ability to understand and follow connections within a family tree. These questions often require you to deduce indirect relationships based on direct ones.

Key terms to understand:

  • Parent: Father or Mother.
  • Sibling: Brother or Sister.
  • Child: Son or Daughter.
  • Grandparent: Parent of a Parent (Father's father, Mother's father, Father's mother, Mother's mother).
  • Grandchild: Child of a Child (Son's son, Son's daughter, Daughter's son, Daughter's daughter).
  • Uncle/Aunt: Sibling of a Parent.
  • Nephew/Niece: Child of a Sibling.

Drawing a simple diagram or family tree can often help visualize the relationships and make the deduction process easier and less prone to errors.
