Simple Interest Calculation Explained
The question asks for the principal sum (P) that generates a specific simple interest (SI) over a given time period (T) at a certain annual interest rate (R).
Formula for Simple Interest
The formula for calculating Simple Interest is:
\( SI = \frac{P \times R \times T}{100} \)
Where:
- SI = Simple Interest
- P = Principal Sum
- R = Rate of Interest (per year)
- T = Time Period (in years)
Finding the Principal Sum (P)
We need to rearrange the formula to solve for P:
\( P = \frac{SI \times 100}{R \times T} \)
Applying Given Values
From the question, we have:
- SI = ₹480
- T = 2 years
- R = 12% per year
Substitute these values into the rearranged formula:
\( P = \frac{480 \times 100}{12 \times 2} \)
Calculation Steps
- Calculate the product of Rate and Time: \(12 \times 2 = 24\).
- Multiply the Simple Interest by 100: \(480 \times 100 = 48000\).
- Divide the result from step 2 by the result from step 1: \( P = \frac{48000}{24} \).
- Perform the division: \(P = 2000\).
Therefore, the principal sum required is ₹2000.
