How to use percentage?

Last updated at Dec. 16, 2024 by

Sometimes we are given statements like

20% of 10

      or

80% of 400

 

But what does that mean?

Here, 10 is the total value

& we have to find 20% of it

 

How do we find it?

We replace ‘of’ with ×

20%  of 10 = 20% × 10

          = 20/100 × 10

  = 2/10 × 10

  = 2

 

Similarly,

80%  of 400 = 80% × 400

     = 80/100 × 400

     = 80/1 × 4

                     = 320
