Let’s solve it step by step.
Fix a reference
Assume T is at a position.
Only one girl sits between S and T
So S is either 2nd to the left or right of T.
Use P and R condition
P sits immediate left of R (since facing centre → left = clockwise)
So arrangement: R → P (clockwise)
Apply “P is not neighbour of S”
So P cannot sit next to S.
Try valid arrangement
One correct circular order (clockwise):
T → Q → S → R → P
Check conditions:
One between S and T → Q ✔️
P immediate left of R → R → P ✔️
P not neighbour of S → P is next to R and T, not S ✔️
Third to the right of T (right = anticlockwise):
T → P (1) → R (2) → S (3)
Answer: S
