How to Evaluate successive percentage changes
The concept of percentages may be a bit difficult to grasp for some beginner level learners. This video attempts to explain the concept of percentages in an easy to understand way. The concept of percentages is explained by using 10 percentage as a base - which of course has the same meaning as dividing a number by 10. Once we know this value, any multiple of 10 viz 20 percent, 30 percent etc can be calculated by simply multiplying the number by the appropriate number. The same analogy can be applied to 5 percent (10 divided by 2) and 1 percent (number divided by 100).
