How many people live between J and M?

The correct answer is
Two

To find the number of people between J and M, we need to determine the exact floor placement for each person based on the clues provided.

Step-by-Step Floor Mapping

"Only L lives above Y"

This means L must be on the topmost floor (Floor 6), and Y must be on the floor immediately below it (Floor 5). No one else can be above Y except L.

"Only M lives below K"

This implies that M is on the very bottom floor (Floor 1) and K is on the floor immediately above it (Floor 2). No one else can be below K except M.

"I lives on some floor below J"

We have two floors left: Floor 3 and Floor 4.

Since I is below J, J must be on Floor 4 and I must be on Floor 3.
