A person says that his son is 5 times as old as his daughter and his wife is 5 times older than his son and he is twice the age of his wife . The sum total of all the ages equals the age of the grand mother who celebrated her 81st birthday today. How old was his son? Correct Answer 50 yrs

Let the daughter age be 'x'Therefore, Son age = 5x, Mother age = 25x, Person age = 50x.

Thus we get, x+5x+25x+50x = 8181x = 81x = 1

Daughter's age = 1, Son's = 5, Mother's = 25, Person's age = 50.
