She worked for 1/10 of her life before she got married.
She was married for 2/5 of her life.
Her husband died after 7/10 of her life.

How old is aunt Helen?
:
Let a = Helen's present age
:
From the statement "Her husband died after 7/10 of her life."
and
"she has been a widow for 24 years." (we can ignore the other statements);
a = 7%2F10a + 24
a - 7%2F10a = 24
3%2F10a = 24
3a = 10*24
3a = 240
a = 240/3
a = 80 yrs old is Helen
