2) 27+54= 81 (кв.) однокомнатных и двухкомнатных

3) 320-81= 239 (кв.) трёхкомнатных

Answer 2

Calculating the Number of Three-Room Apartments in the Building

In a sixteen-story building with 20 apartments on each floor, the total number of apartments in the building can be calculated as follows:

Total number of apartments = Number of floors * Number of apartments per floor Total number of apartments = 16 * 20 Total number of apartments = 320

Now, we know that there are 27 one-room apartments and 54 two-room apartments in the building. To find the number of three-room apartments, we can use the following formula:

Number of three-room apartments = Total number of apartments - (Number of one-room apartments + Number of two-room apartments) Number of three-room apartments = 320 - (27 + 54) Number of three-room apartments = 320 - 81 Number of three-room apartments = 239

So, there are 239 three-room apartments in the building.

Conclusion

In the sixteen-story building with 20 apartments on each floor, there are a total of 239 three-room apartments.
