    Answer: (1) 140 years

    Explanation:-
    The ratio of ages of two person = 5: 9
    Let the age of first person be 5X and the age of second person be 9X

    The age of one of them is greater than the other by 40 years,
    Then, 9 X – 5 X = 40
    4 X  = 40
    X = 40/4
    X = 10

    Then, the age of first person is 5 X = 5 x 10 = 50 years and the age of second person 9X = 9 x 10 = 90 years

    So, the sum of their ages = 90 + 50 = 140 years

    Hence, the answer is (1) 140 years.
