Building: 3 floors, 3 flats each (A west, B middle, C east). Each flat has 2520 sq ft. Various room-count and room-area constraints given. What is the area of a room in Flat B on floor 2?

340
360
396
either (a) or (c)

Correct answer: 360

Solution

Floor 2 total rooms=15. From various area constraints and the room distribution pattern: Flat A floor 2 has fewer rooms than Flat C, which has fewer than Flat B. Working through room area constraints: Flat B floor 2 room area=360 sq ft (7 rooms: 2520/360=7).
