    Answer: (2) 192

    Explanation:-
    The ratio of first and second numbers = 2: 3
    The ratio of second and third numbers = 5: 8

    Then, the ratio of first, second and third numbers = 2 x 5: 3 x 5: 3 x 8
    = 10: 15: 24

    The sum of the three numbers = 392
    Then, 10X + 15X + 24X = 392
    59 X = 392
    X = 392/59
    X = 8

    Then, the value of third number is 24X = 24 x 8 = 192

    Hence, the answer is (2) 192.
