Eight persons $A,B,C,D,E,F,G$ and $H$ are sitting around a circular table, each facing the center. $D$ is second to the left of $F$ and third to the right of $H$. $A$ is second to the right of $F$ and an immediate neighbor of $H$. $C$ is second to the right of $B$, and $F$ is third to the right of $B$. $G$ is not an immediate neighbor of $F$. Based on the above information, who is sitting to the immediate left of $A$?

Let's systematically assign positions ($1$ to $8$) in a counter-clockwise circle layout. When facing the center, moving counter-clockwise represents "Right" and moving clockwise represents "Left".
1. Place $F$ at position $1$.
2. "$D$ is second to the left of $F$ ": Move $2$ places clockwise from $F$. $D$ is at position $3$.
3. "$D$ is third to the right of $H$ ": This implies $H$ must be $3$ places clockwise from $D$. So, $H$ is at position $6$.
4. "$A$ is second to the right of $F$ ": Move $2$ places counter-clockwise from $F$. $A$ is at position $7$. Note that $A$ (at $7$) is next to $H$ (at $6$), matching the condition.
5. "$F$ is third to the right of $B$ ": This means $B$ is $3$ places clockwise from $F$. So, $B$ is at position $4$.
6. "$C$ is second to the right of $B$ ": Move $2$ places counter-clockwise from $B$. $C$ is at position $2$.

Let's check the current seat status:

* Position 1: $F$
* Position 2: $C$
* Position 3: $D$
* Position 4: $B$
* Position 5: Empty
* Position 6: $H$
* Position 7: $A$
* Position 8: Empty

7. We have two remaining people, $G$ and $E$, and two empty spots, $5$ and $8$.
8. The rule says "$G$ is not an immediate neighbor of $F$ ". Since position $8$ is adjacent to $F$ (at position $1$), $G$ cannot sit at $8$. Therefore, $G$ must sit at position $5$.
9. This leaves position $8$ for $E$.

The final order in the circle is:

$$\text{F (1) }\to \text{ C (2) }\to \text{ D (3) }\to \text{ B (4) }\to \text{ G (5) }\to \text{ H (6) }\to \text{ A (7) }\to \text{ E (8)}$$

The question asks for the person sitting to the immediate left of $A$. Facing the center at position $7$, the immediate left (clockwise step) points directly to position $8$, which is occupied by **$E$ **.
