Q: Suman ranks 39th from the bottom in a class. What is her rank from the top?

Rajan ranks 12th from the top and 34th from the bottom in the same class.
Statement II:

Correct option is C

Given:
Suman ranks 39th from the bottom in a class.
We are asked to find her rank from the top.
Statement I:
Rajan ranks 12th from the top and 34th from the bottom in the same class.
Logic:
From this, total students in the class can be found.
Explanation:
Total students = 12 + 34 − 1 = 45
Now Suman’s rank from the top =
45 − 39 + 1 = 7
So, Statement I alone is sufficient.
Statement II:
There are 45 students in the class.
Logic:
Total strength is directly given.
Explanation:
Suman’s rank from the top =
45 − 39 + 1 = 7
So, Statement II alone is also sufficient.
Conclusion:
Either Statement I or Statement II alone is sufficient to answer the question.
Thus, correct option is (C).
