Five colleagues $A, B, C, D,$ and $E$ are seated in a row facing North. $B$ is sitting to the immediate right of $E$. $C$ is between $A$ and $D$. If $D$ is at the extreme right end and $A$ is to the immediate right of $B$, who is seated at the exact middle position? (Enter 1 for A, 2 for B, 3 for C, 4 for D, 5 for E)
Answer Key:
1
Step-by-Step Solution & Explanation
Order from left to right:
- $B$ is immediately right of $E$: $(E, B)$.
- $A$ is immediately right of $B$: $(E, B, A)$.
- $D$ is at extreme right and $C$ is between $A$ and $D$: $(E, B, A, C, D)$.
Seating sequence: $E, B, A, C, D$.
The middle person is $A$ (corresponding to code 1).
