In a certain code language, A + B means 'A is the daughter of B', A - B means 'A is the brother of B’. A × B means 'A is the son of B' and A ÷ B means 'A is the husband of B’. Based on the above, how is M related to O If 'H ÷ O + A - M + N'?

Understanding Blood Relations in Code Language
This question asks us to decipher relationships expressed in a specific code language and then determine how two individuals are related based on a given expression. Let's break down the code and the expression step-by-step.
Decoding the Relationships
The problem provides a set of rules defining relationships using operators:
- A + B means 'A is the daughter of B'
- A - B means 'A is the brother of B'
- A × B means 'A is the son of B'
- A ÷ B means 'A is the husband of B'
Analyzing the Expression: H ÷ O + A - M + N
We need to analyze the given expression from left to right to build the family tree or understand the connections between the individuals.
- H ÷ O: According to the rule, 'A ÷ B' means 'A is the husband of B'. So, H is the husband of O. This tells us H is male and O is female. They are a couple.
- O + A: According to the rule, 'A + B' means 'A is the daughter of B'. So, O is the daughter of A. This confirms O is female (consistent with step 1) and places A one generation above O. A is O's parent.
- A - M: According to the rule, 'A - B' means 'A is the brother of B'. So, A is the brother of M. This tells us A is male and A and M are siblings, belonging to the same generation.
- M + N: According to the rule, 'A + B' means 'A is the daughter of B'. So, M is the daughter of N. This tells us M is female and places N one generation above M. N is M's parent.
Constructing the Family Connections
Let's consolidate the relationships we've derived:
- H is married to O (H is male, O is female).
- O is the daughter of A. This means A is O's parent.
- A is the brother of M. This means A and M are siblings.
- M is the daughter of N. This means N is M's parent.
From these points, we can infer more:
- Since O is the daughter of A, and A is male (brother of M), A must be O's father.
- A is the brother of M, and M is female (daughter of N). So, M is A's sister.
Determining the Relationship between M and O
We want to find out how M is related to O.
- O's father is A.
- M is A's sister.
Therefore, M is O's father's sister.
Checking the Options
Let's look at the provided options and see which one matches our finding:
| Option | Relationship |
|---|---|
| 1 | Father's wife |
| 2 | Father's mother |
| 3 | Fathers sister |
| 4 | Brother's mother |
Our conclusion is that M is O's father's sister. Option 3 matches this relationship exactly.
Conclusion on M's Relationship to O
Based on the step-by-step analysis of the coded expression 'H ÷ O + A - M + N', we have determined the relationships between the individuals involved. O is the daughter of A, making A her father. A is the brother of M, and M is the daughter of N, making M A's sister. Therefore, M is the sister of O's father.
Revision Table: Key Relationship Codes
| Code | Relationship Meaning | Gender of First Person (A) |
|---|---|---|
| A + B | A is daughter of B | Female |
| A - B | A is brother of B | Male |
| A × B | A is son of B | Male |
| A ÷ B | A is husband of B | Male |
Additional Information on Blood Relations
Blood relation questions in competitive exams test your ability to interpret coded relationships or complex statements and build a family tree. Key aspects to remember include:
- Generations: Clearly identify who is in which generation (grandparents, parents, children, grandchildren).
- Genders: Determine the gender of each person whenever the code or statement provides this information.
- Siblings and Spouses: Distinguish between relationships within the same generation (siblings, cousins, spouses) and across generations.
- Step-by-Step Analysis: For coded relations, always break down the expression segment by segment to avoid errors.
- Visual Representation: Drawing a diagram or family tree can be very helpful in visualizing the relationships and solving the problem accurately. Use symbols for male (\(\square\)), female (\(\bigcirc\)), marriage (\(\leftrightarrow\)), and siblings (\(-\)). Children are typically placed below parents.
Mastering these concepts is crucial for solving blood relation puzzles effectively in various exams.
