Solving Blood Relation Puzzles
This problem involves decoding a set of relationships defined by specific symbols and then using them to determine the relationship between two individuals based on a given expression. Let's break down the process step-by-step.
Understanding the Relationship Codes
The question provides a set of codes that represent different relationships. It is crucial to understand each one accurately:
A + Bmeans ‘B is the daughter of A’. This tells us A is a parent of B, and B is female.A - Bmeans ‘B is the sister of A’. This tells us A and B are siblings, and B is female. A's gender is not specified by this relation.A × Bmeans ‘B is the husband of A’. This tells us A and B are a married couple, A is female (wife), and B is male (husband).A ÷ Bmeans ‘A is the father of B’. This tells us A is a parent of B, and A is male. B's gender is not specified by this relation.
Analyzing the Blood Relation Expression
The given expression is: P ÷ R × T + Q - S × U + Z. We need to decode this expression segment by segment from left to right.
P ÷ R: According to the ruleA ÷ Bmeans 'A is the father of B', this means P is the father of R. P is male.R × T: According to the ruleA × Bmeans 'B is the husband of A', this means T is the husband of R. So, R is the wife of T. R is female, and T is male. Since P is R's father, P is T's father-in-law.T + Q: According to the ruleA + Bmeans 'B is the daughter of A', this means Q is the daughter of T. Q is female. Since T is married to R, Q is also the daughter of R. So, Q is the child of both R and T.Q - S: According to the ruleA - Bmeans 'B is the sister of A', this means S is the sister of Q. S is female. Since Q is the child of R and T, and S is Q's sister, S is also the child of R and T. Q and S are siblings.S × U: According to the ruleA × Bmeans 'B is the husband of A', this means U is the husband of S. So, S is the wife of U. S is female, and U is male. S and U are a married couple.U + Z: According to the ruleA + Bmeans 'B is the daughter of A', this means Z is the daughter of U. Z is female. Since U is married to S, Z is also the daughter of S. So, Z is the child of both S and U.
Building the Family Tree Structure
Based on the analysis, we can visualize the family connections:
| Relationship | Individuals | Genders Inferred |
|---|---|---|
| P is father of R | P → R | P (Male), R (Child of P) |
| R is wife of T | R — T (Married) | R (Female), T (Male) |
| Q is daughter of T | T → Q | Q (Female) |
| S is sister of Q | Q — S (Siblings) | S (Female) |
| U is husband of S | S — U (Married) | S (Female), U (Male) |
| Z is daughter of U | U → Z | Z (Female) |
Combining these steps:
- P is the father of R.
- R is married to T. R and T are parents.
- Q is the daughter of R and T.
- S is the sister of Q. S is also the daughter of R and T.
- S is married to U. S and U are parents.
- Z is the daughter of S and U.
Determining the Relationship Between R and Z
We need to find how R is related to Z. Let's trace the connection:
- R is the mother of S (since S is the daughter of R and T, and R is female).
- S is the mother of Z (since Z is the daughter of S and U, and S is female).
So, R is the mother of S, and S is the mother of Z. This means R is the mother of Z's mother.
The mother of one's mother is the maternal grandmother.
Therefore, R is the maternal grandmother of Z.
Final Check of Blood Relations
Let's verify the steps:
- P (Male) is R's father.
- R (Female) is married to T (Male). R and T are parents.
- Q (Female) is daughter of R and T.
- S (Female) is sister of Q, so S is also daughter of R and T.
- S (Female) is married to U (Male). S and U are parents.
- Z (Female) is daughter of S and U.
R is S's mother. S is Z's mother. Thus, R is Z's maternal grandmother.
Revision Table for Blood Relations
| Symbol | Meaning | Gender Clue |
|---|---|---|
| + | B is daughter of A | B (Female) |
| - | B is sister of A | B (Female) |
| × | B is husband of A | A (Female), B (Male) |
| ÷ | A is father of B | A (Male) |
Additional Information on Blood Relations
Blood relation questions test your ability to decode relationships and build a family tree. Key terms to remember include:
- Paternal: Related through the father's side of the family.
- Maternal: Related through the mother's side of the family.
- Grandfather: Father of your father (paternal) or mother (maternal).
- Grandmother: Mother of your father (paternal) or mother (maternal).
- Siblings: Brothers or sisters.
- In-laws: Relatives by marriage (e.g., father-in-law, mother-in-law, sister-in-law, brother-in-law).
Always pay attention to the gender indications provided by the symbols and trace the relations carefully to avoid confusion. Drawing a simple diagram can be very helpful in visualizing the connections.
