Answer 1

Answer:E 83
`(1)/(3)`

Explanation:

50% of the apartment in a certain building have windows and hardwood floors.

25% of the remaining 50% apartment without window have hardwood floors.

40% of the apartment do not have hardwood floors i.e. 60 % have hardwood floor

Therefore percent of the apartments with windows have hardwood floors is

`=(50 percent of total\ apartment )/(60\ percent\ of\ apartment)`

=83
`(1)/(3)`%
