That sounds like the start of a classic riddle, but it’s incomplete. There are many versions that begin with “This woman was born in 1975…” and the answer depends on the rest of the clues.
For example, one common version goes:
“This woman was born in 1975 and died in 1975. How is that possible?”
Answer: 1975 is a room number, not a year.
