Chapter-2 Compound Interest [without using formula]

This is very important and you can expect at least 2-3 questions from an examination point of view. The topics like simple interest, compound interest, their differences, applications, etc are clearly explained here with examples and exercises for better understanding. Also, the relationship between simple interest and compound interest, and explaining each term like rate, principle, are discussed with simple problems.

Chapter-3 Compound Interest [using formula]
