A, B, C, D, E and F 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. E lives on an even numbered floor but not 6. The sum of floors on
which A and E live is 7. F lives immediately above B. The sum of floors on which E and
D live is 3. How many people live between A and D?
Correct Answer:
C. 3
Explanation:
Based on the conditions provided, E resides on the 2nd floor since the sum of E and D's floors is 3, placing D on the 1st floor. Given that the sum of A and E's floors is 7, A must live on the 5th floor. Consequently, there are three floors (2nd, 3rd, and 4th) between A and D, meaning 3 people live between them.
