In a class Rahi is ranked 20th from top in Mathematics and 25th from below in English.
How many students are there in the class?

Answer: D. Inadequate data

The correct answer is D. Inadequate data.
To find the total, you need the top and bottom rank for the same subject.
Rahi’s ranks are given for two different subjects (Math and English).
A student's rank can be completely different in each subject.
Without a second rank for either specific subject, the total is impossible to calculate.
Therefore, the provided information is insufficient.
