Given:

90 for every 100.

To Find:

90 for every 100 is the same as what value for every 200.

Solution:

The given question can be solved very easily as shown below.

Given that,

90 for every 100.

Let us find what is the percentage of 90 in 100.

⇒ Percentage of 90 in 100 = ( 90 / 100 ) × 100 = 90%

So in every 100, the value should be 90%.

Then let us find what is the value of 90% in 200.

⇒ 90% in 200 = ( 90 / 100 ) × 200 = 0.9 × 200 = 180

Therefore 90 for every 100 is the same as 180 for every 200.
