Question

Given the expression $D @ N @ H & Y @ F \% V$ with the following code meanings:

- $D @ N$: D is the daughter of N.
- $N @ H$: N is the daughter of H.
- $H & Y$: H is the husband of Y.
- $Y @ F$: Y is the daughter of F.
- $F \% V$: F is the wife of V.

What is the relationship between $N$ and $F$?

Accepted Answer

**Solution:**

1. Decode each relationship:
   - $D @ N$: D is daughter of N.
   - $N @ H$: N is daughter of H.
   - $H & Y$: H is husband of Y (Y is wife of H).
   - $Y @ F$: Y is daughter of F.
   - $F \% V$: F is wife of V.

2. Construct family tree:
   - D is daughter of N.
   - N is daughter of H and Y (since H & Y are husband and wife).
   - Y is daughter of F.
   - F is wife of V.

3. Relationship between N and F:
   - Y is daughter of F.
   - N is daughter of Y.
   - Therefore, N is granddaughter of F, or "daughter's daughter".

**Answer:** Daughter's daughter
