    Answer:

    The constant of variation is 3

    Step-by-step explanation:

    Given.

    y=81

    x=27

    And y is directly related to x

    yx

    Here k is constant of variation

    y=kx

    k=\frac{y}{x}————–(1)

    Put the y and x value in equation 1.

    k=\frac{81}{27}

    k=3

    So, the constant of variation is 3.
