I, J, K, U, V and W live on six different floors of the same building. The lowermost floor in the building is numbered 1, the floor above it, number 2 and so on, till the topmost floor is numbered 6. Only two people live between V and J. Only K lives above W. U lives on an even numbered floor. V lives on the lowermost floor. How many people live between I and K?

Correct Answer: Two

Step-by-Step Explanation:

Let's determine the floor positions of the six individuals (numbered 1 to 6, where 1 is the bottommost floor and 6 is the topmost floor) based on the given clues:

1. "V lives on the lowermost floor."
This directly places V on Floor 1.

2. "Only two people live between V and J."
Since V is on Floor 1, counting two floors above V (Floors 2 and 3), J must live on Floor 4.

3. "Only K lives above W."
This means K is on the topmost floor, which is Floor 6, and W is directly below K on Floor 5.

4. "U lives on an even numbered floor."
The available even-numbered floors are 2, 4, and 6. Floors 4 and 6 are already occupied by J and K, respectively. Therefore, U must live on Floor 2.

5. Remaining Person:
The only remaining floor is Floor 3, which must be occupied by I.

Floor Arrangement Summary:
Floor 6: K
Floor 5: W
Floor 4: J
Floor 3: I
Floor 2: U
Floor 1: V

Finding the Solution:
The question asks: "How many people live between I and K?"
- K is on Floor 6.
- I is on Floor 3.
- The people living between them are W (Floor 5) and J (Floor 4).

Thus, exactly Two people live between I and K.
