2 alone is sufficient while 1 alone is not sufficient to answer the given question.
Either 1 or 2 is sufficient to answer the given question.
Both 1 and 2 are sufficient to answer the given question.
1 alone is sufficient while 2 alone is not sufficient to answer the given question.

Answer 1

From statement 1: Y’s rank is 4 ranks below that of X and 30^th from the bottom.

Thus X’s rank is 34^th from the bottom.

As the total number of students is 50, X’s rank from the top will be 50 – 34 + 1 = 17

From statement 2: Z’s rank is 2 ranks above that of X and 32^nd from the bottom.

Thus, X’s rank is 30^th from the bottom.

As the total number of students is 50, X’s rank from the top will be 50 – 30 + 1 = 21

So, we can say that either 1 or 2 is sufficient to answer the given question.
