    Answer:

    first number =4x

    second number =2x

    third number =x

    (4x + 2x+ x)/3 =70

    7x/3 = 70

    7x = 70×3

    7x = 210

    x=30

    first number = 4x

    =4×30 = 120

    second number= 2x

    = 2×30 = 60

    third number= x

    =30

    so your required answer is 120
