Correct Answer: $\frac{20}{11}\%$

Solution : Time = 55 years
Principal = $\text{P}$
Rate = $\text{r}$
Amount = $\text{2P}$
Simple interest = Amount – Principal = $\text{2P – P = P}$
We know that,
Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$
$⇒\text{P} = \frac{\text{P × r × 55}}{100}$
$⇒\text{r} =
