If 'A + B' means 'A is the daughter of B ', 'A × B' means 'A is the sister of B', and 'A = B' means 'A is the wife of B', then how is G related to R in the expression 'C × G × U + M = R'?
Let's analyze the given expression step by step using the provided relationship codes:
- 'A + B' means 'A is the daughter of B'
- 'A × B' means 'A is the sister of B'
- 'A = B' means 'A is the wife of B'
The expression is: C × G × U + M = R
We need to find the relationship between G and R.
Let's break down the expression from left to right:
-
C × G: According to the code 'A × B' meaning 'A is the sister of B', this means C is the sister of G.
- This establishes C and G are siblings.
- C is female.
- G's gender is not yet determined from this part.
-
G × U: Again, using the code 'A × B' meaning 'A is the sister of B', this means G is the sister of U.
- This establishes G and U are siblings.
- G is female.
- U's gender is not yet determined from this part.
From steps 1 and 2, we know that C, G, and U are siblings. C is female, and G is female. U's gender is still unknown at this point.
-
U + M: According to the code 'A + B' meaning 'A is the daughter of B', this means U is the daughter of M.
- This establishes M is a parent of U.
- U is female (daughter).
- M's gender is not yet determined from this part.
Now we know that C, G, and U are siblings, and all three (C, G, U) are female. M is a parent to U. Since they are all siblings, M must be a parent to C and G as well.
-
M = R: According to the code 'A = B' meaning 'A is the wife of B', this means M is the wife of R.
- This establishes M and R are a married couple.
- M is female (wife).
- R is male (husband).
Putting all the information together:
- C, G, and U are siblings, all are female.
- M is a parent of C, G, and U.
- M is the wife of R.
- Therefore, R must be the other parent of C, G, and U, and R is the husband of M.
- This means R is the father of C, G, and U, and M is the mother of C, G, and U.
We need to determine how G is related to R.
From our analysis, G is one of the children of R, and G is female.
Therefore, G is the daughter of R.
Let's check the given options:
| Option | Relationship | Correct? |
|---|---|---|
| 1 | Son | Incorrect (G is female) |
| 2 | Mother | Incorrect (G is a generation below R) |
| 3 | Daughter | Correct (G is female and in the generation below R, with R being the parent) |
| 4 | Sister | Incorrect (G and R are in different generations) |
The analysis clearly shows that G is the daughter of R.
Blood Relation Problem Solving
Solving blood relation problems from coded relationships involves carefully decoding each part of the expression and building a family tree or relationship diagram. It's crucial to correctly identify the gender and generation of each person involved based on the codes.
- Break down the expression into smaller parts based on the operators (+, ×, =).
- Decode each part to determine the immediate relationship and gender if specified.
- Combine the relationships sequentially to build a complete picture of the family structure.
- Finally, determine the relationship between the two individuals asked in the question.
Revision Table: Coded Relationships
| Code | Meaning | A's Relationship to B | B's Relationship to A |
|---|---|---|---|
| A + B | A is the daughter of B | Daughter | Parent |
| A × B | A is the sister of B | Sister | Sibling |
| A = B | A is the wife of B | Wife | Husband |
Additional Information: Understanding Blood Relations
Blood relations questions test your ability to understand and deduce relationships within a family structure based on given information. Key terms and concepts include:
- Generation: Levels in a family tree (e.g., Grandparents, Parents, Children, Grandchildren).
- Gender: Male or Female.
- Siblings: Brothers and Sisters.
- Spouse: Husband or Wife.
- Parent: Father or Mother.
- Child: Son or Daughter.
In coded blood relation problems, the operators (+, ×, =) act as bridges connecting individuals and defining their relationships. Pay close attention to which person (A or B) is related to the other in the defined manner.
