Analyzing Blood Relations to Find the Incorrect Statement
This question asks us to interpret a complex expression representing family relationships using a given set of codes and then identify which of the provided statements about these relationships is not correct.
Understanding the Blood Relation Codes
First, let's list the meaning of each code provided:
| Code | Meaning |
|---|---|
| A + B | A is the father of B |
| A - B | A is the wife of B |
| A × B | A is the brother of B |
| A ÷ B | A is the son of B |
Breaking Down the Expression M × R × Q + F + S - D ÷ U
Now, let's break down the given expression segment by segment to determine the relationships between the individuals:
- M × R: According to the code 'A × B' means 'A is the brother of B', so 'M × R' means M is the brother of R. M is male.
- R × Q: Similarly, 'R × Q' means R is the brother of Q. R is male. Since M is brother of R and R is brother of Q, M, R, and Q are siblings. M and R are male. Q's gender is not determined by this part alone.
- Q + F: According to the code 'A + B' means 'A is the father of B', so 'Q + F' means Q is the father of F. Q is male. F's gender is not determined here.
- F + S: 'F + S' means F is the father of S. F is male. S's gender is not determined here.
- S - D: According to the code 'A - B' means 'A is the wife of B', so 'S - D' means S is the wife of D. S is female. D is male.
- D ÷ U: According to the code 'A ÷ B' means 'A is the son of B', so 'D ÷ U' means D is the son of U. D is male. U is the parent of D; U's gender is not determined here.
Synthesizing the Family Tree and Relationships
Let's consolidate the relationships and genders we've found:
- M, R, and Q are siblings. M is male, R is male, and Q is male (as Q is the father of F).
- Q is the father of F. (Q is male)
- F is the father of S. (F is male)
- S is the wife of D. (S is female, D is male)
- D is the son of U. (D is male)
From these relations, we can deduce further:
- Since Q is the father of F, and F is the father of S, Q is the grandfather of S. As Q is male, Q is the paternal grandfather of S.
- Since F is the father of S, and S is the wife of D, F is the father of D's wife. Thus, F is the father-in-law of D.
- Since Q is the father of F, and M is the brother of Q, M is the brother of F's father. Thus, M is the paternal uncle of F. (M is male).
- Since D is the son of U, and S is the wife of D, S is the wife of U's son. Thus, S is the daughter-in-law of U.
Evaluating the Statements
Now let's check each given statement against our deduced relationships:
- Q is the maternal grandfather of S.
We determined that Q is the father of F, who is the father of S. Q is a male grandfather. The father of your father is your paternal grandfather. Therefore, Q is the paternal grandfather of S. This statement claims Q is the maternal grandfather, which is incorrect.
- F is the father-in-law of D.
We determined that S is the wife of D, and F is the father of S. The father of one's wife is their father-in-law. This statement is correct.
- M is the paternal uncle of F.
We determined that Q is the father of F, and M is the brother of Q. The brother of one's father is their paternal uncle. M is male. This statement is correct.
- S is the daughter-in-law of U.
We determined that D is the son of U, and S is the wife of D. The wife of one's son is their daughter-in-law. This statement is correct.
The question asks for the statement that is NOT correct. Based on our evaluation, the statement "Q is the maternal grandfather of S" is incorrect.

| Q + F | Q is father of F | Q (Male, Father), F (Child of Q) |
| F + S | F is father of S | F (Male, Father), S (Child of F) |
| S - D | S is wife of D | S (Female, Wife), D (Male, Husband) |
| D ÷ U | D is son of U | D (Male, Son), U (Parent of D) |
| Q, F, S | Q is father of F, F is father of S | Q is paternal grandfather of S |
| F, S, D | F is father of S, S is wife of D | F is father-in-law of D |
| M, Q, F | M is brother of Q, Q is father of F | M is paternal uncle of F |
| S, D, U | S is wife of D, D is son of U | S is daughter-in-law of U |
Additional Information on Blood Relation Concepts
Blood relation questions test your ability to understand and decipher familial relationships based on given information. The key is to build a clear picture of the family structure, often mentally or by drawing a diagram, and carefully determine the gender of each person whenever possible.
- Paternal vs. Maternal: Paternal relations involve the father's side of the family (e.g., paternal uncle is father's brother, paternal grandfather is father's father). Maternal relations involve the mother's side (e.g., maternal aunt is mother's sister, maternal grandfather is mother's father).
- In-laws: These relations are created through marriage (e.g., father-in-law is spouse's father, daughter-in-law is son's wife).
- Solving Strategy: Start from one end of the expression and build relationships link by link. Note down the gender of individuals as you deduce them. Then, evaluate the statements using the complete set of relationships you've established.
