Consider the given question and decide which of the following statement is sufficient to answer the question. What is X’s rank from the top in a class of 50 students? Statements: 1. Y’s rank is 4 ranks below that of X and 30th from the bottom. 2. Z’s rank is 2 ranks above that of X and 32nd from the bottom. Correct Answer Either 1 or 2 is sufficient to answer the given question.
From statement 1: Y’s rank is 4 ranks below that of X and 30th from the bottom.
Thus X’s rank is 34th 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 32nd from the bottom.
Thus, X’s rank is 30th 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.
