Answer: 66/7 years old.
The answer does not make sense to me, though. When I also checked it, the value of z is negative, which is weird.
Please reply if you have corrections to my solution. Thanks! :)
Hi Sir,
Hi Sir,
For the first highlighted phrase, "...was when Mary was three times as old as Ann is now."
There is no "is now" from the problem.
Hint 1: This problem / riddle was made popular from around the year 1900.
Hint 2: Mary is 27 years and 6 months (1/2 year).
Hint 3: I solved this using tabular method.

Well, they say great minds
Well, they say great minds think alike. And we all agree that our minds are great, right?
Years ago, I stumbled on the "How old is Ann?" puzzle while thumbing through an old copy of Bartlett's Familiar Quotations. During the current pandemic, with some time on my hands, I decided to make a somewhat humorous YouTube based on that puzzle. It took me a lot longer than I thought it would, but I finally posted it.
When I searched for it last week, I was pleasantly surprised to learn that folks at Mathalino had worked on it, too -- although yours is somewhat different from my 1903 version.
You might get a kick out of my video:
