To solve this seating arrangement problem, let's break down the given information and rearrange the positions accordingly.
- There are five senior citizens: P, Q, R, S, and T.
- S is positioned in the middle of the row. Thus, S sits at the third position.
| _ | _ | S | _ | _ |
- T and P are adjacent to S. Therefore, they sit next to S in position 2 and 4, but the exact positions are not fixed yet.
- Q is not adjacent to R, meaning Q and R cannot be next to each other.
- T is not adjacent to R. Therefore, T cannot be directly next to R.
Therefore, the only possible initial arrangement is:
| Q | P | S | T | R |
Now, we interchange the positions of P and T as specified.
| Q | T | S | P | R |
- After interchanging, we analyze the positions of T and Q. In this arrangement, there are two people between T and Q as depicted.
Therefore, the correct answer is 2. There are two people between T and Q after P and T interchange their positions.
