Four people—W, X, Y, and Z—live on different floors of a four-story building (1st to 4th). W lives on a higher floor than X. Y lives on a lower floor than Z. X lives on a higher floor than Z. List the residents from the 1st floor up to the 4th floor.
Y, Z, X, W
We know X > Z and W > X, giving us the chain W > X > Z. We also know Z > Y. Combining these gives the complete vertical order from bottom to top: Y (1st), Z (2nd), X (3rd), W (4th).
