Calculation of the Number of Two-Bedroom Apartments

To calculate the number of two-bedroom apartments in the building, we need to determine the total number of apartments and then subtract the number of one-bedroom apartments.

Given that 30% of the apartments are one-bedroom and five-sixths are two-bedroom, we can set up the following equation:

Let N be the total number of apartments in the building.

Number of one-bedroom apartments = 30% of N = 0.3N

Number of two-bedroom apartments = five-sixths of N = (5/6)N

To find the number of two-bedroom apartments, we subtract the number of one-bedroom apartments from the total number of apartments:

Number of two-bedroom apartments = (5/6)N - 0.3N

Simplifying the expression, we have:

Number of two-bedroom apartments = (5/6 - 0.3)N

Now we can calculate the number of two-bedroom apartments using the given information.

Please note that the exact value of N (the total number of apartments) is not provided in the question, so we cannot determine the specific number of two-bedroom apartments without that information.
