A person invests Rs 5000 at a simple interest rate of 8 % per annum for 3 years. What is the total interest earned by the person at the end of the period?
Rs 1000
Rs 1200
Rs 1400
Rs 1600
To solve the problem, we need to calculate the simple interest earned over a period based on the principal amount, rate of interest, and time.
- Principal (P): The initial amount invested.
- Rate of Interest (R): The annual rate at which interest is earned.
- Time (T): The duration for which the money is invested (in years).
- Simple Interest (SI): The interest earned over the period, calculated as: \( \text{SI} = \frac{P \times R \times T}{100} \)
\( P = \text{Rs } 5000 \)
\( R = 8\% \text{ per annum} \)
\( T = 3 \text{ years} \)
\[ \text{SI} = \frac{5000 \times 8 \times 3}{100} = \frac{120000}{100} = \text{Rs } 1200 \]
The total interest earned by the person at the end of the period is Rs 1200.
