The problem involves finding the annual compound interest rate given the amounts at the end of the first and second years.
Interest Earned (Year 2) = Amount (Year 2) - Amount (Year 1)
Interest Earned (Year 2) = ₹550 - ₹500 = ₹50
$R = \frac{\text{Interest Earned}}{\text{Principal Amount}} \times 100$
$R = \frac{50}{500} \times 100$
$R = \frac{1}{10} \times 100$
$R = 10\%$
Therefore, the rate of compound interest is 10% per annum.
Find the interest (in ₹) on ₹8,000 at 10% per annum compounded half yearly for $1\frac{1}{2}$ years.
The difference between the compound interest and the simple interest on a principal sum of $₹24,000$ in $2$ years at same rate of interest is $₹60$. The rate of interest is:
Amit had invested same amount of sums at simple as well as compound interest, compounded annually. The time period of investment for both the sums was 2 years and rate of interest too was the same, 4% per annum. At the end, he found a difference of ₹43 in both the interests received. What were the sums (in ₹) invested?
When the difference between compound interest, compounded annually, and simple interest for three years is ₹186 at 10% interest per annum, the principal is ₹______.
