Ordering and Ranking

Q: On which floor does A live in a 5-story building (Ground is 1st)? I. B lives on an even-numbered floor and A lives immediately above B. II. C lives on the 4th floor.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, B lives on an even floor (2 or 4) and A lives immediately above B (3 or 5). From II, C lives on the 4th floor. If C is on 4th, B cannot be on 4th. So B is on 2nd, which means A is on the 3rd floor. Both are required.

Q: How many boxes are placed below Box X? I. Box X is at the topmost position in a stack of 6 boxes. II. There are exactly 5 boxes placed below Box X.

Correct Answer: Option D (Each statement alone is sufficient.). From I, Box X is placed at the topmost position of a stack of 6 boxes. Therefore, there are 5 boxes below it. Sufficient. From II, Box X is placed exactly above a stack of 5 boxes. This also means there are 5 boxes below it. Sufficient. Each statement alone is sufficient.

Q: Which book is placed at the bottom of the stack of 4 books (P, Q, R, S)? I. Book P is placed above both Q and R. II. Book S is placed immediately below Q and immediately above R.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, P is above Q and R. From II, S is below Q but above R. Combining: P > Q > S > R. R is at the bottom. Both are required.

Q: Who lives on the 2nd floor of a 4-story building? I. M lives on the top floor and N lives on the ground floor. II. O lives somewhere above P.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, M is on top (4th) and N is on 1st. From II, O lives above P. Since 2nd and 3rd are empty, O must be on 3rd and P on 2nd. Both are required.

Q: How many floors are there in the building? I. X lives on the 5th floor from the bottom. II. X lives on the 4th floor from the top.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, X is on the 5th floor from bottom. From II, X is on the 4th floor from the top. Total floors = (5 + 4) - 1 = 8. Both are required.
