Finding the Principal Sum
The formula for simple interest (SI) is given by: $SI = \frac{P \times R \times T}{100}$ where P is the principal sum, R is the annual interest rate (in percent), and T is the time period (in years).
From the first scenario, we have: SI = ₹500 T = 4 years R = 5% per annum
We can rearrange the formula to find the principal sum (P): $P = \frac{SI \times 100}{R \times T}$
Substitute the given values:
$P = \frac{500 \times 100}{5 \times 4}$
$P = \frac{50000}{20}$
$P = ₹2500$
So, the principal sum of money is ₹2,500.
Calculating the New Simple Interest
Now, we need to calculate the simple interest for the second scenario using the same principal sum (P = ₹2,500): T = 6 years R = 7% per annum
Using the simple interest formula:
$SI = \frac{P \times R \times T}{100}$
$SI = \frac{2500 \times 7 \times 6}{100}$
$SI = 25 \times 7 \times 6$
$SI = 25 \times 42$
$SI = ₹1050$
Therefore, the simple interest on the same sum for 6 years at 7% per annum would be ₹1,050.
