In a certain code language, A + B means 'A is the mother of B' A - B means 'A is the brother of B' A × B means 'A is the wife of B' A ÷ B means 'A is the father of B' Based on the above, how is B related to E if 'A - B × C ÷ D + E'?
Mother's mother
This question involves decoding relationships based on a given set of rules. We need to analyze the provided expression step-by-step to determine how B is related to E.
Understanding the Blood Relation Code
The problem provides us with a code where symbols represent specific family relationships:
- A + B means 'A is the mother of B'
- A - B means 'A is the brother of B'
- A × B means 'A is the wife of B'
- A ÷ B means 'A is the father of B'
Analyzing the Expression: A - B × C ÷ D + E
Let's break down the given expression piece by piece, applying the rules to understand the relationships between the individuals A, B, C, D, and E.
The expression is A - B × C ÷ D + E.
Step-by-Step Relationship Deduction
- A - B: According to the code, A - B means 'A is the brother of B'. This tells us that A is a male and is B's sibling.
- B × C: The next part is B × C. The code says A × B means 'A is the wife of B'. Applying this rule, B × C means 'B is the wife of C'. This tells us that B is a female and C is her husband.
- C ÷ D: The next part is C ÷ D. The code says A ÷ B means 'A is the father of B'. Applying this rule, C ÷ D means 'C is the father of D'. We already know C is the husband of B, so if C is the father of D, then B must be the mother of D.
- D + E: The final part is D + E. The code says A + B means 'A is the mother of B'. Applying this rule, D + E means 'D is the mother of E'. This tells us D is a female and E is her child.
Combining the Relationships to Find B's Relation to E
Let's put the deduced relationships together:
- B is the mother of D (from Step 3).
- D is the mother of E (from Step 4).
If B is the mother of D, and D is the mother of E, then B is the mother of E's mother. The mother of one's mother is the maternal grandmother.
| Relationship | Interpretation | Gender Information |
|---|---|---|
| A - B | A is brother of B | A is male |
| B × C | B is wife of C | B is female, C is male |
| C ÷ D | C is father of D | C is male |
| D + E | D is mother of E | D is female |
From the table and our step-by-step analysis:
- B is female (from B × C).
- B is mother of D (from B × C and C ÷ D).
- D is mother of E (from D + E).
Therefore, B is the mother of D, and D is the mother of E. This makes B the mother of E's mother.
Concluding the Relationship
The relationship of B to E is that B is E's mother's mother, which is the maternal grandmother.
Revision Table: Blood Relation Coding Rules
| Code | Relation |

| A + B | A is mother of B |
| A - B | A is brother of B |
| A × B | A is wife of B |
| A ÷ B | A is father of B |
Additional Information on Blood Relations
Blood relation questions test your ability to understand and deduce family relationships based on given information or coded language. It's often helpful to draw a family tree or diagram to visualize the relationships described in the problem. Keep track of the gender of each person if provided or deducible from the relations (like mother, father, wife, husband, brother, sister). Terms like maternal grandmother refer to the mother's mother, while paternal grandmother refers to the father's mother.
- Maternal relatives: Relations through the mother's side.
- Paternal relatives: Relations through the father's side.
- In this problem, B is the mother of D, and D is the mother of E. B is on E's mother's side, specifically the generation above E's mother.
