Ordering and Ranking

Q: What is A's rank from the bottom in a class of 50 students? I. A's rank from the top is 15th. II. B's rank from the bottom is 20th, and A is exactly 16 ranks below...

Correct Answer: Option D (Each statement alone is sufficient.). From I, A is 15th from top. Rank from bottom = 50 - 15 + 1 = 36th. Sufficient. From II, B is 20th from bottom and A is 16 ranks below B (towards the bottom). So A's rank from bottom = 20 - 16 = 4th. Sufficient. Each statement alone is sufficient.

Q: What is the position of X from the right end of the row? I. Y is 12th from the right end of the row. II. X is sitting 4th to the left of Y.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, Y is 12th from right. From II, X is 4th to the left of Y. Since Y is 12th from the right, moving 4 places to the left means X is 12 + 4 = 16th from the right end. Both statements are required.

Q: In a row of 30 students facing North, what is P's position from the left end? I. Q is 10th from the right end. II. There are exactly 5 students between P and Q.

Correct Answer: Option D (Statements I and II together are not sufficient.). From I, Q is 10th from the right. Thus, Q is (30 - 10 + 1) = 21st from the left. From II, there are 5 students between P and Q. P could be 15th or 27th from left. Neither is sufficient alone, and even together, P's exact position is ambiguous. The data is NOT sufficient.

Q: What is Rohan's rank in the class? I. Rohan ranks 8th from the top among the students who passed the exam. II. A total of 5 students failed the exam in the class.

Correct Answer: Option D (Statements I and II together are not sufficient.). Statement I gives Rohan's rank relative to passed students only. We don't know his overall rank without knowing if any failed students scored higher or how the ranks are compiled. Statement II just gives the number of failed students. Not sufficient even together.

Q: What is the position of the middle person from the left end in a row of an odd number of people? I. A is 10th from the left end. II. B is 20th from the right end and A sits exact...

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, A is 10th from left. From II, B is 20th from right and A is exactly in the middle. This means A is the middle person. Since A is 10th from the left, the position of the middle person is 10th. Both are required.
