In a five-floor building, offices A-E are assigned one per floor (1=ground, 5=top). A is above B. C is on floor 3. D is above C. E is on an even floor. Which floor is A on?

✓ Correct Answer: Option B

C = floor 3. D > 3, so D = 4 or 5. E is even = 2 or 4. A > B. If D=5, E=2 or 4. If E=4, then A and B get 1 and remaining — A must be above B so A could be at remaining floors above B. A ends up on 4 or 5.
