Question

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’ and   
‘A ÷ B’ means ‘A is the father of B’.

Based on the above, how is A related to D if ‘A × B ÷ C + D’?

Accepted Answer

Let's decode the expression **A × B ÷ C + D** step by step (work from right to left):

#### 1. **C + D:**  
C is the mother of D.

#### 2. **B ÷ C:**  
B is the father of C.

#### 3. **A × B:**  
A is the wife of B.

---

#### **Family tree:**
- C is the mother of D.
- B is the father of C (so B and C are D's grandparents).
- A is the wife of B (so A is C's mother and D's grandmother).

So, **A is the mother of D's mother**.

### Final Answer:
