Hi friends
Here is your answer
Let Sum = x
A = 2x
so SI = x
T = 8 years
Now
Rate of interest = SI × 100/PT
![= \frac{x \times 100}{x \times 8} \\ = 12.5\% = \frac{x \times 100}{x \times 8} \\ = 12.5\%](https://tex.z-dn.net/?f=+%3D++%5Cfrac%7Bx+%5Ctimes+100%7D%7Bx+%5Ctimes+8%7D++%5C%5C++%3D+12.5%5C%25)
Hope it helps you
