Solving Blood Relation Puzzles

Blood relation questions require you to carefully trace the relationship between individuals based on the statements given. Let's break down the statement provided by Vijay to determine how Rukmani's husband is related to him.

Analyzing Vijay's Statement Step-by-Step

Vijay says, “She is my wife’s only brother’s son’s mother.” Let's analyze this statement piece by piece, starting from Vijay's perspective:

  • "my wife's only brother": This refers to Vijay's brother-in-law. Since he is the 'only' brother, this relationship is specific.
  • "my wife's only brother's son": This refers to the son of Vijay's brother-in-law. The son of your brother-in-law is your nephew. So, this is Vijay's nephew.
  • "my wife's only brother's son's mother": This refers to the mother of Vijay's nephew (the son of his brother-in-law). Who is the mother of a child? It's the wife of the child's father. The child's father is Vijay's brother-in-law. Therefore, the mother of this child is the wife of Vijay's brother-in-law.

So, according to Vijay's statement, Rukmani is the wife of his brother-in-law.

Determining the Relation of Rukmani's Husband

We established that Rukmani is the wife of Vijay's brother-in-law. The question asks how Rukmani's husband is related to Vijay.

  • Rukmani's husband is the person whose wife is Rukmani.
  • We know Rukmani is the wife of Vijay's brother-in-law.
  • Therefore, Rukmani's husband is Vijay's brother-in-law.

Comparing with the Options

Based on our analysis, Rukmani's husband is Vijay's brother-in-law. Let's look at the options provided:

  1. Brother-in-law
  2. Son
  3. Father
  4. Father-in-law

Our conclusion matches option 1.

Step-by-Step Derivation:

  1. Vijay's wife's only brother = Vijay's Brother-in-law.
  2. Vijay's wife's only brother's son = Son of Vijay's Brother-in-law = Vijay's Nephew.
  3. Vijay's wife's only brother's son's mother = Mother of Vijay's Nephew.
  4. The mother of a nephew is the wife of the nephew's father. The nephew's father is Vijay's Brother-in-law.
  5. So, Rukmani is the wife of Vijay's Brother-in-law.
  6. Rukmani's husband is the person whose wife is Rukmani.
  7. Therefore, Rukmani's husband is Vijay's Brother-in-law.
