A family decides to meet up.
Anthony is 96 years old
Bernard is 80 years old
Barry is 24 years old
Melanie is 60 years old.
How old is Helen and why are they a family?
The given names are "nicknames" of cities that hosted the Summer Olympics, and the age is how long ago they hosted
Anthony (96) : Antwerp in 1920
Bernard (80) : Berlin in 1936
Barry (24) : Barcelona in 1992
Melanie (60) : Melbourne in 1956
