Solving the Family Relationship Puzzle
Let's break down the given information about the six members of the business family: P, L, T, B, N, and D.
- "N is the son of B, who is not the mother of N."
- This tells us B is a parent of N.
- Since B is not the mother, B must be the father of N.
- "L is the brother of B."
- This establishes L's relationship to B, but it doesn't directly connect L to N or T yet.
- "D and B are a married couple."
- We know B is N's father.
- Since D is married to B, and B is N's father, D must be N's mother.
- "T is the daughter of D."
- D is the mother (from step 3). T is her daughter.
- "D is the sister of P."
- This establishes D's relationship to P, but it doesn't directly connect P to N or T yet.
Building the Family Connections
From the statements, we can piece together the core family unit involving N, T, B, and D:
- B is the father of N.
- D is married to B, making D the mother of N.
- So, N's parents are B (father) and D (mother).
- T is the daughter of D.
- Since T's mother is D, and N's mother is also D (married to B, N's father), T and N share the same mother, D, and the same father, B.
Therefore, N and T are siblings.
Determining the Relationship Between N and T
We know N is the son of B and D, and T is the daughter of D and B. Siblings who are male are brothers, and siblings who are female are sisters.
- N is identified as the son of B.
- T is identified as the daughter of D.
Since N is the male sibling and T is the female sibling, N is the brother of T.
Let's summarize the relevant relationships derived:
| Member | Relationship |
|---|---|
| B | Father of N |
| D | Mother of N, Mother of T |
| N | Son of B and D |
| T | Daughter of D and B |
Based on the analysis, N is the son and T is the daughter, and they share the same parents. Thus, N is the brother of T.
Revision Table: Key Family Relationship Concepts
| Relationship | Definition | Example (from this problem) |
|---|---|---|
| Parent | A father or mother. | B is a parent of N (father), D is a parent of N (mother). |
| Child | A son or daughter. | N is a child of B and D (son), T is a child of D (daughter). |
| Siblings | Children sharing at least one common parent. | N and T are siblings as they share parents B and D. |
| Brother | A male sibling. | N is a brother (male sibling of T). |
| Sister | A female sibling. | T is a sister (female sibling of N). |
| Spouse | A husband or wife. | B and D are spouses. |
Additional Information: Understanding Blood Relations Questions
Blood relation questions in reasoning tests require you to deduce the relationship between two people based on a series of connected relationships given in the question. Here are some tips for solving them:
- Start with the most direct relationships (like parent-child or husband-wife).
- Use diagrams or family trees to visualize the connections. Represent males with one symbol (e.g., a square or +) and females with another (e.g., a circle or -). Show marriage with a double line and siblings with a single line.
- Break down complex sentences into smaller, manageable pieces of information.
- Carefully note the gender of each person whenever mentioned.
- Work step-by-step from one known relationship to the next until you connect the two people in question.
In this specific problem, identifying B as N's father and D as B's wife (and thus N's mother) was crucial. Once N and T were linked to the same parents (B and D), their relationship as siblings became clear, and their stated genders confirmed N as the brother of T.
