Eight friends J, K, L, M, N, O, P and Q live on eight different floors of a building but not necessarily in the same order. The lowermost floor of the building is numbered one, the one above that is numbered two and so on until the topmost floor is numbered eight.<br /> J lives on floor numbered six.<br /> Only one person lives between J and L.<br /> O lives on the floor immediately below L.<br /> Only one person lives between O and P.<br /> O lives above P.<br /> K lives on an even-numbered floor but not on the floor numbered two.<br /> Two persons live between K and Q.<br /> Q does not live on the lowermost floor.<br /> N lives on one of the floors above Q.<br /> Who amongst the following lives on the floor number eight?
Step-by-step Solution:
This question is part of a larger floor arrangement puzzle. To answer it, we must first use all the clues to determine the correct placement of all eight friends.
A complete, step-by-step analysis of all the clues ("J lives on floor six", "Two persons live between K and Q", etc.) leads to one unique and final arrangement of the friends on the eight floors (from bottom to top):
(The key deduction involves placing J on floor 6, testing the two possible positions for L, and finding that only one of them allows for a valid placement of K and Q).
The question asks who lives on floor number eight.
Looking at our completed arrangement, the person on the topmost floor (8) is K.
Final Answer: K lives on the floor number eight.
