The age of the mother over Anna is:
33 - 5 = 28 ( year old)
Anna's age when her mother is 5 times older is:
28:(5-1) = 7 (year old)
The number of years that the mother is 5 times older than Anna is:
7 - 5 = 2(year)
The difference in ages of mother and daughter is:
33 - 5 = 28 (age )
Mother's age is 5 times more than her son's age => Mother's age = \(\frac{5}{4}\) Age difference.
Mother's age at that time was:
28 x = 35 (age )
Then and now:
35 - 33 = 2 (years)
