Seven people — Amit, Bina, Chetan, Deepa, Esha, Farin and Gopal — live on a seven-floor building (floor 1 is the bottom, floor 7 is the top), one person per floor. Chetan lives on the topmost floor. Amit lives immediately below Chetan. Gopal lives immediately below Amit. Only one person lives between Gopal and Esha. Bina lives immediately above Esha. Farin lives on the lowest floor. Deepa lives immediately above Farin. If everyone is re-seated in alphabetical order from bottom (floor 1) to top (floor 7), how many people stay on the same floor as before?

Question

Accepted Answer

None. Current bottom-to-top: Farin, Deepa, Esha, Bina, Gopal, Amit, Chetan. Alphabetical bottom-to-top: Amit, Bina, Chetan, Deepa, Esha, Farin, Gopal. Comparing floor by floor, no person occupies the same floor in both — so none stay put.
