Answer
There are 13 Residents of Babelfish Court.If we start by adding up the number of people who speak 1 language only.
1 speaks Italian only
3 speak Greek only
Equals 4 people
Then add up those who speak more than one language.
3 speak Greek, Italian and English
2 speak Greek and Italian
2 speak Italian and English
1 speak English and Greek
Equals 8 people
4 + 8 = 12
However if you look at the people that speak more than one language 6 of them speak English but the clues tell you that 7 people speak English, hence 1 person speaks English only.
So
4 + 8 + 1 = 13 Residents
