Seven people — G, H, I, J, K, L and M — live on a seven-storey building, floor 1 at the bottom to floor 7 at the top, one person per floor. K lives on the topmost floor. Only one person lives between K and L. Exactly three people live between G and H, and G lives above H. J lives immediately above I. I lives on an odd-numbered floor. Who lives on the 4th floor?

Question

Accepted Answer

J. K=7. One person between K and L puts L=5. Three between G and H with G above H, avoiding floors 5 and 7, gives H=2, G=6. Remaining floors 1,3,4 for I,J,M with J immediately above I forces I=3, J=4, M=1. So the 4th floor is J.
