    Three numbers are : 6, 21 and 3

    Step-by-step explanation:

    Given,

    Ratio of 3 numbers is 2:7:1.

    We can assume 3 numbers as : 2x, 7x and x respectively.

    According to the problem:

    2x + 7x + x = 30 {The sum of the 3 numbers is 30}

    10x = 30

    x = 3

    Hence 3 numbers are, x = 3

    2x = 2*3 = 6

    7x = 7*3 = 21

    Therefore we get three numbers as : 6, 21 and 3

    Remember, you can check their ratios to cross check the correct answer.
