Show the answer and the worked solution
Correct answer: C. 24th
Worked solution
- Rank from the top = 35 − 12 + 1 = 24th.
Answer: 24th.
The idea
The +1 accounts for the student being counted at both ends. Subtracting alone gives 23, the offered trap.
Shortcut. 35 − 12 = 23 students rank above Priya, so she is the 24th from the top.
Common trap. "23rd" — subtracting 12 from 35, which counts the students above her rather than giving her own position.
