A2577

B2573

C2571

D2575

Answer:

D. 2575

Read Explanation:

We use the simple interest formula:
SI=P×R×T100\text{SI} = \frac{P \times R \times T}{100}

Given:
SI = 824
Rate (R = 8%) per annum
Time (T = 4) years

Substitute values

824=P×8×4100824 = \frac{P \times 8 \times 4}{100}
824=32P100824 = \frac{32P}{100}
P=824×10032P = \frac{824 \times 100}{32}
P=2575P = 2575

Principal amount = INR 2,575
