Show the answer and the worked solution
Correct answer: B. 25
Worked solution
- Rank from the bottom = 40 − 16 + 1 = 25.
Answer: 25.
The idea
The +1 is needed because both ranks count the person themselves. Simply subtracting gives 24, the offered trap.
Shortcut. 15 students rank above Meera, so she and everyone below her number 40 − 15 = 25 — she is 25th from the bottom.
Common trap. "24" — subtracting 16 from 40, which counts the students below her rather than giving her own rank.
