Hey

Here is your answer,

36/90 = 90/x
12/90 = 30/x
4/90 = 10/x
X = 10 x 90/4
X = 5 x 45
X = 225

Hope it helps you!

Answer 2

Given:

36, 90, x

To find:

The value of x

Solution:

The value of x is 225.

We can find the value by following the given process-

We know that the given numbers are in proportion.

So, 36, 90, x are in proportion.

This means that 36:90::90:x.

Now, we know that when the given terms are in proportion, the product of means is equal to the product of extremes.

The terms as extremes= 36 and x

The term as means= 90

So, the product of extremes=product of means

Using the values, we get

90×90=36×x

8100=36×x

8100/36=x

900/4=x

225=x

Therefore, the value of x is 225.
