Solving Blood Relation Puzzles: Understanding Family Connections

Blood relation questions test your ability to decipher relationships based on given statements. To solve this type of puzzle, it's helpful to break down the statement into smaller parts and build a family tree or trace the connections step-by-step.

The statement given is: “My sister-in-law S’s husband Q's son N had a sister R”.

Let's analyze the statement part by part to understand the relationships described:

Analyzing the Statement for Blood Relations

  • The statement starts with the speaker referring to “My sister-in-law S”. This tells us about S's relationship to the speaker, but it's not directly needed to find the relationship between S and R. The core part of the puzzle involves the chain starting from S.
  • “S’s husband Q”: This establishes that Q is the husband of S. This also means S is the wife of Q.
  • “Q's son N”: This means N is the son of Q. Since S is Q's wife, N is also the son of S. So, N is the son of both S and Q.
  • “N had a sister R”: This means R is the sister of N. Children of the same parents are siblings. Since N is the son of S and Q, and R is N's sister, R must also be the child of S and Q. Specifically, if N is the son and R is his sister, then R is the daughter of S and Q.

Tracing the Relationship Between S and R

Based on the analysis:

  1. Q is the husband of S.
  2. N is the son of Q (and thus also the son of S).
  3. R is the sister of N.

If N is the son of S, and R is N's sister, then R is the daughter of S.

Concluding the Relationship: S and R

We have determined that R is the daughter of S. The question asks: “How is S related to R?”

If R is the daughter of S, then S is the mother of R.

Summary of Relationships

Person Relationship
Q Husband of S
N Son of Q (and S)
R Sister of N (and Daughter of Q and S)
S Mother of R

Therefore, S is related to R as the Mother.

Additional Information on Blood Relation Puzzles

Blood relation problems are common in reasoning sections of competitive exams. They require careful reading and logical deduction. Here are some tips for solving them:

  • Read the statement carefully, identifying the key individuals and relationships.
  • Break down complex statements into smaller, manageable parts.
  • Work backward from the end of the statement or forward from the start, tracing the connections.
  • Draw a family tree diagram if the relationships are complex. Use symbols like a double-headed arrow for marriage, vertical lines for parent-child relationships, and horizontal lines for siblings.
  • Pay close attention to gender where specified (son, daughter, sister, brother).
  • Be mindful of terms like 'my', 'his', 'her' which refer back to the speaker or a previously mentioned person.
  • Practice different types of blood relation questions to improve speed and accuracy.

Understanding the basic family relationships is crucial for mastering these puzzles.
