$\huge \blue{ \overline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }}$

Let the principal be Rs.x.

As it is 100% increased so it becomes Rs. 2x.

Interest = 2x - x = Rs.x.

$\huge \blue{ \overline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }}$

$\sf{ \tt{Now,  SI = \frac{P×R×T}{100} }} \\ \sf{ \tt{x = \frac{x \times R×8 }{100} }} \\ { \tt{R s= 12.5\%}}$

Now CI on Rs.8000 for 2 years is given by —

${ \tt{CI = 8000 ×(1 + \frac{12.5}{100}) {}^{2} - 8000 }}$

${ \tt{Ci = 8000 ×(1 + \frac{1}{8}) {}^{2} - 8000 = 8000 \times }} \\ { \tt{ \frac{9}{8} \times \frac{9}{8} - 8000 }}$

${ \tt{ = \frac{81000 - 64000}{8} = \frac{17000}{8} = { \boxed{Rs. \blue{2125}}}}}$
