The question below is followed by two statements numbered I and II. Decide whether the data given in the statements are sufficient to answer the question.
In a class of 45 students, no two students have the same rank. What is Karan’s rank from the top?
I. Karan’s rank from the bottom is 31st.
II. Exactly 14 students have a better rank than Karan.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Either statement I alone or statement II alone is sufficient.
In a class of \(n\) students, rank from the top \(=n+1-\) rank from the bottom.
Statement I alone:
Rank from the top \(=45+1-31=\) 15th: sufficient
Statement II alone:
14 students are ahead of Karan, so his rank from the top is \(14+1=\) 15th: sufficient
