Each floor has a certain number of flats and each flat has a certain number of people living in it. The information about each building is given below. Building A: The number of floors in building A is same as number of floors in building C. The number of flats per floor in is equal to the product of the smallest and the second smallest prime numbers. The total number of people living in building A is √ 1764.

The number of flats per floor in building B is the same as the number of floors in building A. The total number of people in building B is 6 time the number of people in building A. Building C: The number of floors in building is √ 2401. The number of flats per floor in building C is one less than the number of flats per floor in building A.
