In a meeting, seven teachers are sitting in a row. T3 is sitting to the left of T2 but to the right of T4. T1 is sitting to the right of T2. T6 is sitting to the right of T5 but to the left of T4. T7 is sitting to the left of T5. Who is sitting in the middle?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → T4
Each clue says who is somewhere to the left of whom. Written from left to right, the clues link up into one chain:
T7 is to the left of T5
T5 is to the left of T6
T6 is to the left of T4
T4 is to the left of T3 (T3 is to the right of T4)
T3 is to the left of T2
T2 is to the left of T1
The chain covers all seven teachers, so the order is fixed: T7, T5, T6, T4, T3, T2, T1. The middle (4th) seat has three teachers on each side, and it is T4's.
