Final answer:
To calculate the simple interest on ₹ 30,000 for 3 years at a 15% interest rate, multiply the principal, rate, and time to get ₹ 13,500 interest. The total future amount would be ₹ 43,500.
Step-by-step explanation:
The calculation of simple interest involves finding the interest earned on a principal sum of money at a certain interest rate over a fixed period of time. To compute the simple interest on a sum of ₹ 30,000 for 3 years at an interest rate of 15%, you would use the formula:
Simple Interest = Principal × Rate × Time
In this case, it would be:
Simple Interest = ₹ 30,000 × 0.15 × 3
After performing the calculation, we find the simple interest to be:
Simple Interest = ₹ 13,500
The total future amount with simple interest can then be calculated by adding the original principal amount to the simple interest earned:
Total future amount = Principal + Simple Interest
Total future amount = ₹ 30,000 + ₹ 13,500
Total future amount = ₹ 43,500
