The preliminary expression for the percentage is:
Percentage (%) = (Part / Whole) × 100
Let’s take a simple example:
You got 45 marks out of 50 in a test.
Percentage = (45 / 50) 100 = 90%
To find 30% of 200:
(30 / 100) × 200 = 60
To see how much 20 is of 80:
(20 / 80) × 100 = 25%
To increase 200 by 10%:
New Value = 200 + (10/100 × 200) = 200 + 20 = 220
To decrease 200 by 10%:
New Value = 200 - (10% × 200) = 180
