Nine persons Polomi, Rachel, Manushi, Trisha, Lisa, Rudra, Charles, and Drishti live in a building with nine floors, not necessarily in the same order. The topmost floor is numbered 1; the floor below floor 1 is numbered 2, and so on till the lowest floor, numbered 9. Polomi lives three floors below Lisa. Lisa and Rachel live on the lowermost and topmost floors, but not necessarily in the same order. Trisha does not live on a floor immediately above or below the floor on which Rachel lives. Mathew lives on the floor immediately above the floor on which Rudra lives. Drishti lives on an odd-numbered floor below Polomi. Rudra lives on an odd-numbered floor. Manushi lives immediately below Drishti. Charles lives on the floor on which Trisha lives. Question: Four of the following belong to a group. Find the member who does not belong to the group.
- Mathew
- Manushi
- Trisha
- Drishti
Correct answer: Drishti
Solution
The arrangement creates a chain involving Mathew, Rudra, Manushi, and Trisha through direct floor relations. Drishti is not part of that same linked group in the final arrangement, so she is the odd one out.
