Answer» Person: A, B, C, D, E, F, G and H. Retirement year: 2019, 2020, 2021, 2022, 2023, 2024, 2025 and 2026. 1) C lives on 7th FLOOR and going to retire 2 years before D. 2) D lives on odd numbered floor but it is not the lower most floor. 3) F, who lives 2 floors above D is going to retire in 2020. Hence, D must be living on 3rd floor and F on 5th floor.
4) B will retire before only two persons and he lives 3 floors above E. Hence, B will retire in 2024. And only possible position for E and B are 1st and 4th floor respectively.
5) G lives on the topmost floor and will retire 2 years before H. 6) A lives below H and will retire 1 year after H.
7) A will retire at the end of everyone. Hence, (Y + 1) = 2026 Adjusting the remaining VALUES according to that:
Now remaining years are 2019, 2021 and 2022. Only possible value of X is 2021.
