Explanation:

- The arrangement is based on 7 people: A, C, F, J, N, R, and V, facing north.

- J sits third from one end, placing them in seats 3 or 5. Assume J is at seat 5.

- V's father is two seats right of J, so in seat 7.

- V's sister sits such that 3 people are between her and V's father. Hence, V's sister is in seat 3.

- As many people sit to the left of V's sister as to V's mother's right, so V's mother is in seat 4.

- N is next to V’s mother. N is in seat 6.

- N is the son of C, so C is V's father in seat 7.

- A sits third right of C, so A is in seat 3. This conflicts, so J must be at seat 3, hence C at seat 5.

- V's wife is second left of V, placing V at seat 7.

- R sits adjacent to V’s father (C), with F right of R.

1. N

2. V's wife

3. J

4. V's mother

5. C

6. F

7. V's wife
