  2. Answer:

    let the three numbers be x,y,z

    sum of the three numbers

    x+y+z = 4917

    their ratios x:y:z = 3⅓ : 4⅕ : 6⅛

    converting into improper fractions

    x:y:z = 10/3 : 21/5 : 49/8

    they all should have a common factor. let it be k

    x = 10/3 k

    y = 21/5 k

    z = 49/8 k

    substituting

    10/3 k + 21/5 k + 49/8 k = 4917

    400k + 504k + 735k / 120 = 4917

    1639k / 120 = 4917

    k = 3×120

    k = 360

    applying the values

    x = 10/3 × 360

    x = 1200

    y = 21/5 × 360

    y = 1512

    z = 49/8 × 360

    z = 2205

    so the numbers are 1200, 1512, 2205
