How Percentages Work
A percentage is a number out of 100. To find 20% of 500, you multiply 500 by 20 and divide by 100, which gives 100. The same idea works for discounts: a 20% discount on a Rs 500 item saves you Rs 100, so you pay Rs 400.
For exam results, divide your obtained marks by the total marks and multiply by 100. For example, 450 out of 500 is 90%. Students in Pakistan, India and Bangladesh use this every year to check board and university results.
