Show the answer and the worked solution

- Counting from the top: S (1st), P (2nd), Q (3rd).
Answer: Q.
The idea
Order everyone first, then count from whichever end the question names. Counting from the wrong end is the usual slip.
Shortcut. With five people, third tallest is the median — two above, two below. Q has P and S above and R and T below, so it is Q whichever end is counted from.
Common trap. "R" — skipping the clue 'S is taller than P' leaves P > Q > R > T, where third from the top is R.
