Study the given information carefully and answer the following question. Nine people A, B, C, D, E, F, G, H, and J are living on different floors of a building, not necessarily in the same order, such that four floors remain vacant. The ground floor is numbered 1, the first floor is numbered 2, and so on. The top and bottom floors of the building are vacant. There are four floors between A and G. A lives above G. Two persons live between the floors on which H and D live. A lives immediately below H. G is not living on an odd-numbered floor. G lives immediately above a vacant floor. The number of floors between the floors on which C and J live is the same as the number of floors between the floors on which G and B live. C lives on a floor above J and G. D lives immediately below a vacant floor. No two vacant floors are immediate neighbours. At most three floors are there between two vacant floors. The difference between the floors on which F and E live is a prime number, with F living above E. Four among the five are the same and thus form a group. Who among the following does not belong to that group?
- H
- C
- G
- A
Correct answer: H
Solution
This is a floor arrangement puzzle with multiple constraints. Solving the positions of the people and vacant floors shows that three of the options fit the same positional pattern, while H differs from them. Hence, H does not belong to the group.
