Answer 1

Hiiii....friend,

Here is ur answer,

Let the fourth proportion be t.

=> 4xy:2x^2::5y^2: t

We know that product of mean= product of extreme.

$= > 2 {x}^{2} (5 {y}^{2} ) = 4xy(t)$

$= > 10 ({xy)}^{2} = 4xyt$

$= > t = \frac{5xy}{2}$

So, The fourth proportion is 5xy/2.

:-) Hope it helps u.
