In the city, there is a block of flats. This block has 12 floors. Half of the floors have 6 apartments and the other half have 5 apartments. One apartment can accommodate a maximum of 4 residents. What is the maximum number of residents that can live in this block of flats?
How many floors are there? ** Half of the floors have different numbers of apartments. Half the number of floors is 12 floors / 2 = <<12/2=6>>6 floors.
How many apartments are there? ** One half of the block consists of 6 floors * 6 apartments/floor = <<6*6=36>>36 apartments.
How many apartments are there? ** And the other half consists of 6 floors * 5 apartments/floor = <<6*5=30>>30 apartments.
How many apartments are there? ** There are 30 + 36 = <<30+36=66>>66 apartments on all floors in the block.
What is the maximum number of residents that can live in this block of flats? ** All the apartments can therefore accommodate 66 apartments * 4 residents/apartment = <<66*4=264>>264 residents.
