The simple interest on a principal amount is Rs. 714 for a period of 3 years at the rate of 7% per annum.

Correct option is A

Given:
SI = 714, R = 7%, T = 3 years
Formula Used:
$$SI = \frac{P \times R \times T}{100}$$​
Solution:

$$714 = \frac{P \times 7 \times 3}{100} \\\ \\P = \frac{714 \times 100}{21} \\\ \\P = 3400$$​​
