‘A + B’ means ‘A is the wife of B’. ‘A – B’ means ‘A is the husband of B’. ‘A × B’ means ‘A is the son of B’. ‘A ÷ B’ means ‘A is the mother of B’. If T + Q × P – U ÷ R ÷ S + V, the how is R related to Q?

Decoding Blood Relations: Solving the Code Puzzle
This question requires us to decode a series of relationships expressed using mathematical symbols and then determine the relationship between two individuals, R and Q, based on the given expression: T + Q × P – U ÷ R ÷ S + V.
Understanding the Coded Relationships
Let's first understand what each symbol represents:
A + Bmeans A is the wife of B. This implies B is the husband of A.A – Bmeans A is the husband of B. This implies B is the wife of A.A × Bmeans A is the son of B. This implies B is the parent of A.A ÷ Bmeans A is the mother of B. This implies B is the child of A.
We can summarize these rules in a table:
| Symbol | Relation (A to B) | Implied Relation (B to A) |
|---|---|---|
+ |
Wife | Husband |
– |
Husband | Wife |
× |
Son | Parent |
÷ |
Mother | Child |
Breaking Down the Expression: T + Q × P – U ÷ R ÷ S + V
Now let's analyze the given expression segment by segment from left to right:
- T + Q: According to the rule for '+', T is the wife of Q. This means Q is the husband of T. (T is female, Q is male)
- Q × P: According to the rule for '×', Q is the son of P. P is the parent of Q. (Q is male)
- P – U: According to the rule for '–', P is the husband of U. This means U is the wife of P. (P is male, U is female)
- U ÷ R: According to the rule for '÷', U is the mother of R. R is the child of U. (U is female)
- R ÷ S: According to the rule for '÷', R is the mother of S. S is the child of R. (R is female)
- S + V: According to the rule for '+', S is the wife of V. This means V is the husband of S. (S is female, V is male)
Constructing the Family Relationships
Let's combine these relationships:
- T is wife of Q. Q is husband of T.
- Q is son of P.
- P is husband of U. U is wife of P.
- From steps 2 and 3, P and U are the parents of Q. P is the father and U is the mother.
- U is the mother of R. This means R is a child of U. Since Q is also a child of U (and P), Q and R are siblings.
- R is the mother of S. This confirms R is female.
- S is wife of V.
So, we have:
- P (Male) and U (Female) are parents.
- Q (Male) and R (Female) are their children, making them siblings.
- Q is married to T (Female).
- R is mother of S (Female).
- S is married to V (Male).
Determining the Relation of R to Q
We need to find out how R is related to Q. From our analysis, we know that Q and R are both children of U and P. Q is the son and R is the daughter (since R is the mother of S, R must be female). Therefore, R is the sister of Q.
Revision Table: Key Relations
| Expression Segment | Relationship | Gender Inferred |
|---|---|---|
T + Q |
T is wife of Q | T: Female, Q: Male |
Q × P |
Q is son of P | Q: Male |
P – U |
P is husband of U | P: Male, U: Female |
U ÷ R |
U is mother of R | U: Female |
R ÷ S |
R is mother of S | R: Female |
S + V |
S is wife of V | S: Female, V: Male |
Based on the relationships, P and U are parents of Q and R. Since R is female, R is the sister of Q.
Additional Information: Blood Relation Concepts
Blood relation questions test your ability to understand and deduce family relationships based on given information. Coded blood relation problems use symbols or artificial codes to represent relationships. To solve these:
- Identify the code for each relation (e.g.,
+for wife,×for son). - Break down the given expression into smaller parts based on the operators.
- Determine the relationship between the two individuals in each part. Remember to also infer the gender if possible.
- Combine the relationships step-by-step to build a family tree or diagram, or simply list the direct and indirect relationships.
- Finally, trace the path between the two individuals whose relationship is asked and determine their relation. Pay close attention to gender.
Common relationships involved are parent, child, sibling, spouse, grandparent, grandchild, aunt, uncle, niece, nephew, etc.
