Welcome to this video from EduKartik! In this session, we will be solving all the important questions from Exercise 7.2 of Class 8 Maths Chapter 7 - Comparing Quantities. This exercise primarily focuses on a very important and practical topic: Compound Interest (CI). ➡️ What you will learn in this video: Understanding the concept of Compound Interest (CI) and how it differs from Simple Interest (SI). Key Formulas used to calculate Compound Interest: Amount: A = P \left(1 + \frac{R}{100}\right)^n Compound Interest (CI): CI = A - P How to adjust the time (n) and rate (R) when the interest is compounded Half-yearly or Quarterly. Simple and clear solutions to all questions from Exercise 7.2, including: Finding Compound Interest for different time periods. Comparing annual and half-yearly compounding. Using the CI formula in real-life problems (like population growth). After understanding these concepts, you will be able to solve every question related to Compound Interest with confidence!
