A # B means ‘A is the sister of B’. A @ B means ‘A is the son of B’. A & B means ‘A is the father of B’. A % B means ‘A is the mother of B’. If W & Q # T & Y @ M % K, then how is Q related to K?
Solving Blood Relation Puzzles: Decoding the Relationship
This question involves decoding a set of relationships defined by specific symbols and then determining the relationship between two individuals based on a given expression chain. These types of puzzles are common in logical reasoning sections of various exams.
Understanding the Symbol Definitions
We are given the following definitions for the symbols used:
- A # B means ‘A is the sister of B’
- A @ B means ‘A is the son of B’
- A & B means ‘A is the father of B’
- A % B means ‘A is the mother of B’
Analyzing the Given Relation Chain
The relation chain is given as: W & Q # T & Y @ M % K
Let's break this down step-by-step:
- W & Q: Using the definition of '&', this means W is the father of Q.
- Q # T: Using the definition of '#', this means Q is the sister of T.
- T & Y: Using the definition of '&', this means T is the father of Y.
- Y @ M: Using the definition of '@', this means Y is the son of M.
- M % K: Using the definition of '%', this means M is the mother of K.
Tracing the Relationships to Connect Q and K
Now, let's combine these steps to figure out the relationship between Q and K.
- From steps 1 and 2: W is the father of Q, and Q is the sister of T. This implies that W is also the father of T, and Q and T are siblings.
- From steps 3 and 4: T is the father of Y, and Y is the son of M. If T is the father of Y and Y is the son of M, then M must be the mother of Y. This means T and M are a married couple.
- From step 5: M is the mother of K.
Putting it together:
- We want to find the relationship of Q to K.
- Q is the sister of T.
- T is married to M (since T is Y's father and M is Y's mother).
- M is the mother of K.
- If M is K's mother, and T is M's husband, then T is K's father.
- Since Q is the sister of T, Q is the sister of K's father.
Therefore, Q is the father's sister of K.
Confirming the Answer
The relationship we found is 'Father's sister'. Let's check the given options:
- Mother’s sister
- Sister
- Father’s sister
- Father’s mother
Our deduced relationship, 'Father’s sister', matches option 3.
| Expression Part | Relationship | Inference |
|---|---|---|
| W & Q | W is father of Q | - |
| Q # T | Q is sister of T | Q and T are siblings, W is father of T |
| T & Y | T is father of Y | - |
| Y @ M | Y is son of M | M is mother of Y; T and M are parents of Y |
| M % K | M is mother of K | M is K's mother |
Based on the inferences: T is M's husband (Y's parents are T and M). M is K's mother. Therefore, T is K's father. Q is T's sister. Thus, Q is K's father's sister.

Additional Information: Types of Blood Relation Problems
Blood relation problems typically fall into three main categories:
- Decoding Relationships: Like this question, where symbols or codes represent relationships. You need to decode the expression to find the relationship between two people.
- Puzzle Based: A passage or set of statements describes relationships among several people. You need to draw a family tree or diagram to figure out the required relationship.
- Pointing or Introducing: A person introduces another person by pointing or stating relationships in a round-about manner (e.g., "He is the son of the daughter of my father's wife"). You need to simplify the statement to find the relationship.
Practicing different types helps in quickly identifying relationships and avoiding confusion.
