Simple & Compound Interest 01

The video, presented in Hindi, focuses on Simple Interest (साधारण ब्याज) calculations. It explains the core concepts and formulas, contrasting simple interest with compound interest, which banks typically use (3:03-3:16). Here's a breakdown of the key topics and examples covered: Simple Interest Formula (3:20-3:55): The fundamental formula SI = P * R * T / 100 is introduced. P (Principal/मूलधन): The initial amount of money. R (Rate/दर): The interest rate (e.g., 5%, 10%). T (Time/समय): The duration for which the money is lent/borrowed. Calculating Total Amount (Mishra Dhan/मिश्र धन) (4:00-7:04): The concept of Mixed Amount (मिश्र धन) is explained as the sum of Principal + Interest (6:24-7:04). Example: Calculate the total amount after 5 years if ₹1500 is provided at 10% per year (5:10-6:21). The calculated total amount is ₹2250 (6:21). Finding Time for an Amount to Become a Multiple (7:42-13:28): Example: How long will it take for an amount to become 10 times its initial value at a 25% annual rate? The solution shows how to find the time (36 years) by setting up the interest and total amount based on the initial principal (13:15-13:28). Calculating Initial Invested Amount (14:36-22:50): Example: John invested money at 10% simple interest. After 4 years, the total amount earned was ₹770. The problem demonstrates how to work backward to find the initial investment (₹550) (21:23-21:28). Calculating the Interest Rate (23:25-28:28): Example: Manoj deposited ₹29400 for 6 years and received ₹4200 as interest. The rate is calculated as 2 and 8/21% (28:07-28:10). Interest Calculation with Same Rate and Principal (29:25-37:41): Example: If the interest for 5 years is ₹77.50, what would be the interest for 4 years at the same rate and principal? The answer is ₹62 (36:03-36:18). Complex Problem: Relationship Between SI, Amount, and Rate/Time (38:00-47:40): Example: If the simple interest of an amount is 1/4th of the principal, and the number of years is equal to the rate, what is the rate? The rate is found to be 5% (47:40-47:43).
