Concept:In a five-person ranking, rank
1 is the highest and rank
5 is the lowest.
The median rank is
3, so "lower than the median" means rank
4 or rank
5.
Explanation:Given: Dev ranks above Ernesto, and Bala ranks above Chetan.
Since Chetan's rank is lower than the median, Chetan is at rank
4 or rank
5.
Statement (1): Atul is rank
5.
Then Chetan cannot be rank
5, so Chetan is rank
4.
But Bala could still be rank
1,
2, or
3, so the highest rank is not fixed.
Statement (2): Bala is not in the top two ranks.
Chetan can be rank
4 or
5, and different students could be first, so this alone is not sufficient.
Combine both statements: Atul is rank
5, so Chetan is rank
4.
Bala ranks above Chetan, so Bala must be rank
1,
2, or
3.
Statement (2) removes ranks
1 and
2, so Bala must be rank
3.
Only ranks
1 and
2 remain for Dev and Ernesto.
Since Dev ranks above Ernesto, Dev gets rank
1, which is the highest rank.
Thus both statements together are sufficient.
Answer:Option C: BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
