Answer 2

Calculation of Three-Room Apartments in One Building

To calculate the number of three-room apartments in one building, we can use the given information about the total number of apartments and the number of two-room apartments.

Given: - 3 sixteen-story buildings - 20 apartments per floor - All apartments are either two-room or three-room

Calculation:

1. Total number of apartments in one building: - 16 floors * 20 apartments = 320 apartments per building

2. Number of two-room apartments: - 16 floors * 20 apartments * 3 buildings = 960 two-room apartments in total

3. Number of three-room apartments: - Total number of apartments - Number of two-room apartments - 320 apartments - 390 two-room apartments = -70 three-room apartments

Based on the given information, it seems there is a discrepancy in the data provided. The total number of two-room apartments exceeds the total number of apartments in the buildings, which is not logically possible. Therefore, it's important to verify the accuracy of the provided information before making any conclusions.
