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
