How old was Mary
Puzzle
As a companion piece to my problem of "How old was Ann?" and,
by way of apology to Sister Mary,
who was slighted or ignored in the
public controversy of the question,
we present a sketch of the remini-
scent old couple who were respon-
sible for the discussion: "You see," remarked Grandpop, "the combined
ages of Mary and Ann are 44 years,
and Mary is twice as old as Ann
was when Mary was half as old as
Ann will be when Ann is three times
as old as Mary was when Mary was
three times as old as Ann."
How
old is Mary?
