Q: Who lives on the top floor of a 3-story building (Ground is 1st)? I. A lives on an even-numbered floor. II. B lives immediately above

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, A must live on the 2nd floor (the only even floor in a 3-story building). From II, B lives immediately above A, placing B on the 3rd (top) floor. Both are required.

Q: Which box is placed at the absolute bottom of a stack of 3 boxes? I. Box P is placed just below Box Q. II. Box R is placed at the top.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From II, R is at position 3 (top). From I, P is below Q, meaning Q is at position 2 and P is at position 1 (bottom). Both are required.

Q: On which floor does M live in a 4-story building? I. N lives on the 1st floor. II. M lives exactly between N and O.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, N is on the 1st floor. For M to be exactly between N and O, M must be on the 2nd floor and O on the 3rd floor. Both are required.

Q: How many boxes are placed between Box A and Box B? I. Box A is placed exactly in the middle of a stack of 7 boxes. II. Box B is placed at the topmost position.

Correct Answer: Option C (Both statements together are sufficient, but neither statement alone is sufficient.). From I, Box A is at position 4. From II, Box B is at position 7. The boxes between them are at positions 5 and 6. Total = 2 boxes. Both are required.

Q: Who lives on the 3rd floor of a 5-story building? I. X lives exactly 2 floors above Y, who lives on the 1st floor. II. Z lives on the top floor.
