‘A @ B’ means ‘A is the son of B’ ‘A & B’ means ‘A is the mother of B’ ‘A # B’ means ‘A is the daughter of B’ Which of the following options means ‘Q is the wife of S'?
P @ Q & R # S
Understanding Blood Relation Codes
This question asks us to decode a set of relationships represented by symbols and determine which option correctly translates to ‘Q is the wife of S’. Let's first understand the meaning of each symbol provided:
| Symbol | Meaning | Inference about the first person's gender |
|---|---|---|
| @ | A @ B means A is the son of B | A is Male |
| & | A & B means A is the mother of B | A is Female |
| # | A # B means A is the daughter of B | A is Female |
We are looking for an option where Q is the wife of S. This means two things must be true:
- Q must be female.
- S must be male, and they must be a couple (husband and wife).
Analyzing Blood Relation Options
Let's examine each option based on the given code meanings:
Option 1: P @ Q & R # S
- P @ Q: P is the son of Q. (P is male. Q's gender is not determined yet from this part alone).
- Q & R: Q is the mother of R. (Q is female. R's gender is not determined yet).
- R # S: R is the daughter of S. (R is female. S's gender is not determined yet).
Combining these:
- From ‘Q & R’, Q is the mother of R.
- From ‘R # S’, R is the daughter of S.
If Q is the mother of R and R is the daughter of S, then S must be the father of R. Therefore, Q and S are the parents of R.
From ‘Q & R’, we know Q is female. If S is the father of R and Q is the mother of R, then S is the husband of Q. S must be male.
In this option, Q is female and is married to S (who is male), meaning Q is the wife of S.
This option matches the required relationship.
Option 2: R @ S @ Q # P
- R @ S: R is the son of S. (R is male. S's gender is not determined yet).
- S @ Q: S is the son of Q. (S is male. Q's gender is not determined yet).
- Q # P: Q is the daughter of P. (Q is female. P's gender is not determined yet).
In this option, Q is female (from ‘Q # P’), but S is male (from ‘S @ Q’). S is the son of Q. This means Q is the mother of S, not the wife of S.
Option 3: R @ S & Q # P
- R @ S: R is the son of S. (R is male. S's gender is not determined yet).
- S & Q: S is the mother of Q. (S is female. Q's gender is not determined yet).
- Q # P: Q is the daughter of P. (Q is female. P's gender is not determined yet).
In this option, S is female (from ‘S & Q’). For Q to be the wife of S, S must be male. This option is incorrect.
Option 4: P # Q @ R # S
- P # Q: P is the daughter of Q. (P is female. Q's gender is not determined yet).
- Q @ R: Q is the son of R. (Q is male. R's gender is not determined yet).
- R # S: R is the daughter of S. (R is female. S's gender is not determined yet).
In this option, Q is male (from ‘Q @ R’). For Q to be the wife of S, Q must be female. This option is incorrect.
Conclusion on Blood Relation Decoding
Based on the analysis of each option, only the first option, P @ Q & R # S, correctly establishes the relationship where Q is the wife of S by identifying Q as female (mother of R) and S as male (father of R).

Additional Information on Blood Relation Questions
Blood relation questions often involve decoding symbolic relationships. To solve these effectively:
- Carefully note down the meaning of each symbol and the gender implied for the first person in the relationship.
- Break down the given expression in the option into smaller parts based on the symbols.
- Draw a family tree or diagram if it helps visualize the relationships.
- Pay close attention to the gender requirements of the target relationship (e.g., "wife" requires a female person married to a male person).
- Work through each option systematically to see if it satisfies the required relationship.
Practice with different types of blood relation coding questions will improve your ability to quickly decode the relationships and find the correct answer.
