    16:x : : x:25

    \frac{16}{x} = \frac{x}{25}

    16*25 = x*x

    400 = x²

    20 = x

    ANSWER is ; x = 20

    (16:20 : : 20:25)

    _________________________________________

    explain –

    20 * 20 = 400

    it means 400 is the square root of 20.

    x * x = x²

    it means x² is the root of x.
