Understanding the Symbols in Blood Relations
In this blood relations problem, we are given a set of symbols that represent specific relationships between individuals. To solve the problem, we first need to understand what each symbol signifies.
| Symbol | Meaning |
|---|---|
| A @ B | A is the son of B |
| A & B | A is the brother of B |
| A # B | A is the wife of B |
| A ^ B | A is the husband of B |
| A + B | A is the father of B |
Decoding the Blood Relation Expression: Y + M & T # J @ H # R @ P ^ Q
Now, let's break down the given expression piece by piece to determine the relationships between the individuals.
- Y + M: Y is the father of M. (Y is male)
- M & T: M is the brother of T. (M is male, T's gender is unknown yet)
- Since Y is the father of M, and M is the brother of T, Y is also the father of T.
- T # J: T is the wife of J. (T is female, J is male)
- T and J are a married couple.
- Since Y is the father of T, Y is the father of J's wife.
- Y is the father-in-law of J.
- J @ H: J is the son of H. (J is male, H's gender is unknown yet)
- H is a parent of J.
- H # R: H is the wife of R. (H is female, R is male)
- H and R are a married couple.
- Since H is a parent of J, and H is married to R, R is also a parent of J. H and R are the parents of J.
- R @ P: R is the son of P. (R is male, P's gender is unknown yet)
- P is a parent of R.
- P ^ Q: P is the husband of Q. (P is male, Q is female)
- P and Q are a married couple.
- Since P is a parent of R, and P is married to Q, Q is also a parent of R. P and Q are the parents of R.
Summary of Derived Relationships:
- Y is the father of M and T.
- M is the brother of T.
- T is the wife of J (J is the husband of T).
- J is the son of H and R.
- H is the wife of R (R is the husband of H).
- R is the son of P and Q.
- P is the husband of Q (Q is the wife of P).
Evaluating the Given Statements
Now, let's examine each statement based on the relationships we have determined from the expression.
Statement 1: P is the maternal grandfather of J.
J's parents are H and R. J's mother is H. The maternal grandfather of J would be H's father.
We know that R is the father of J. R is the son of P and Q. P is R's father.
Therefore, P is the father of J's father (R). This means P is the paternal grandfather of J, not the maternal grandfather. This statement is incorrect.
Statement 2: Y is the father-in-law of J.
J is married to T (T is his wife). We found that Y is the father of T.
The father of one's spouse is their father-in-law.
Since Y is the father of J's wife (T), Y is the father-in-law of J. This statement is correct.
Statement 3: R is the father of T.
From the expression, we found that Y is the father of T. R is the father of J.
T is married to J. R is J's father. R is not T's father. This statement is incorrect.
Statement 4: Q is the mother of H.
H is married to R. Q is the mother of R.
Q is R's mother, not H's mother. This statement is incorrect.
Based on the analysis, only the second statement is correct.
