Consider two Statements and a Question:

Statement-1: Priya is 4 ranks below Seema and is 31st from the bottom. Statement-2: Ena is 2 ranks above Seema and is 37th from the bottom. Question: What is Seema's rank from the top in the class of 40 students?

Which one of the following is correct in respect of the Statements and the Question?

Explanation

According to the given question, we have 40 students in class.

Statement 1: Priya's rank is 31st from the bottom means Priya is above 30 persons in a class of 40 and below the 9 persons in a class of 40. So, Priya's rank out of 40 from the top is 10th ( $40-30$ ). Also given in this statement that Priya is 4 ranks below Seema.

So Seema's rank is 6th ( $10 - 4$ ).

Therefore statement 1 alone is sufficient to answer the question.

Statement 2: Ena is 37th from the bottom means Ena is above 36 persons in a class of 40 and below the 3 persons in a class of 40, So Ena's rank out of 40 from the top is 4th ( $40 - 36$ ). Also given in this statement that Ena is 2 ranks above Seema.

So Seema's rank is 6th ( $4+2$ ).

Therefore statement 2 alone is sufficient to answer the question.

Hence, Either Statement-1 alone or Statement-2 alone is sufficient to answer the question.
