'A + B' means 'A is the brother of B', 'A × B' means 'A is the father of B', 'A * B' means 'A is the mother of B', If O + M × J + T * D, then how is T related to M?
Daughter
Solving Coded Blood Relation Problems
This question requires us to decode the given relationships and then determine the relationship between two individuals based on the provided expression.
Understanding the Given Codes
We are provided with three coded relationships:
- A + B means A is the brother of B. This tells us A's gender (male) and their relationship to B (sibling).
- A × B means A is the father of B. This tells us A's gender (male) and their relationship to B (parent).
- A * B means A is the mother of B. This tells us A's gender (female) and their relationship to B (parent).
Decoding the Expression: O + M × J + T * D
Let's break down the expression part by part to build the family structure:
- O + M: According to the code 'A + B' means 'A is the brother of B', this means O is the brother of M. This tells us O is male. M is O's sibling, M's gender is not yet determined by this part alone.
- M × J: According to the code 'A × B' means 'A is the father of B', this means M is the father of J. This tells us M is male.
- J + T: According to the code 'A + B' means 'A is the brother of B', this means J is the brother of T. This tells us J is male. T is J's sibling, T's gender is not yet determined by this part alone.
- T * D: According to the code 'A * B' means 'A is the mother of B', this means T is the mother of D. This tells us T is female.
Building the Family Relationships
Let's combine the relationships we've decoded:
- O is the brother of M.
- M is the father of J.
- J is the brother of T. Since J and T are siblings and M is the father of J, M must also be the father of T.
- T is the mother of D.
From these points, we know:
- M is male.
- J and T are children of M (and likely M's spouse, who is not mentioned).
- J is male.
- T is female.
- O is M's brother (M's sibling).
Determining the Relationship between T and M
We need to find out how T is related to M.
From our analysis, we know that M is the father of T, and T is female.
If M is the father and T is his female child, then T is M's Daughter.
Evaluating the Options
Let's look at the given options:
- Daughter: Based on our analysis, T is the daughter of M. This matches our conclusion.
- Sister: T is a child of M, not a sibling of M. So, T cannot be M's sister.
- Daughter-in-law: T is a child of M. A daughter-in-law is the wife of one's son. So, T cannot be M's daughter-in-law.
- Mother: M is the father of T, which means T is his child. So, T cannot be M's mother (unless there's a very unusual scenario like a time loop, which isn't implied here).
The only relationship that fits our derived family structure is Daughter.
Conclusion
By decoding the expression O + M × J + T * D, we found that M is the father of T, and T is female. Therefore, T is the daughter of M.
Revision Table: Coded Blood Relations
| Code | Meaning | Gender Information Provided |
|---|---|---|
| A + B | A is brother of B | A is Male |
| A × B | A is father of B | A is Male |
| A * B | A is mother of B | A is Female |
Additional Information: Solving Blood Relation Puzzles
Blood relation questions in reasoning tests often involve decoding symbols or understanding descriptive relationships. A common strategy is to draw a family tree or diagram to visualize the relationships. Representing males with squares and females with circles, and using arrows or lines to show relationships like parent-child, siblings, or spouses, can be very helpful. Always pay close attention to the gender implied by each relationship description or code.
Key steps for solving these problems:
- Identify all individuals mentioned.
- Decode each part of the expression or statement.
- Determine the gender of individuals where possible.
- Establish links between individuals (parent-child, sibling, spouse, etc.).
- Visualize the relationships, perhaps using a diagram.
- Trace the relationship path between the two individuals asked about.
