The ans is c because each apartment in a building had 2 rooms 2 bathrooms and 1 kitchen. 1 room contains 84 tiles. 2 rooms= 84+84=164. 1 kitchen has 64 tiles and 2 bathrooms = 52 + 52 =104. Now lets add 168+64+104=336. Each building in total had 18816 tiles so divide 18816 b 336. The answer to the problem is C .
