Answer is Right!
Answer is Wrong!
The correct answer is A. 12.19 %.
The formula for simple interest is $I = PRT$, where $I$ is the interest, $P$ is the principal, $R$ is the rate, and $T$ is the time. In this case, we know that $P = 1842$, $R = ?$, $T = 10$, and $I = 2000 – 1842 = 158$. Substituting these values into the formula, we get $158 = 1842 \cdot R \cdot 10$. Solving for $R$, we get $R = \frac{158}{1842 \cdot 10} = 0.01219 = 12.19\%$.
Option B is incorrect because $12.03\%$ is not the rate of simple interest. Option C is incorrect because $11.54\%$ is not the rate of simple interest. Option D is incorrect because $10.29\%$ is not the rate of simple interest.
