Three floors, two flats per floor (A is west of B). Each flat has an area of 576 sq ft. Each flat has a different number of rooms. - One flat on an even floor has room area 64 sq ft. - Total rooms on floor 3 = 7. - The flat with 72 sq ft rooms is on an odd floor. - The flat below the 9-room flat has room area 288 sq ft. - There is one floor between the flats with 192 sq ft and 72 sq ft rooms. - No flat is west of the 6-room flat. How many rooms are on the 2nd floor?

  1. 12
  2. 14
  3. 11
  4. None of these

Correct answer: None of these

Solution

Since each flat area is 576 sq ft, the number of rooms in a flat is 576 divided by the room area. So the possible room counts are 9, 8, 6, and 3 for room areas 64, 72, 96, and 192/288 respectively. Using the clues, the floor-wise arrangement forces the second floor to have a total that is not among 12, 14, or 11. Therefore the correct option is None of these.
