Answer 2

HI bro

This is the answer

(C) is the correct option

Let the initial amount be x

Then, after 8 years, the money will be 2x

Out of 2x rupees, interest will be 2x-(initial amount( x))= x

Let the rate of interest be R

SI= PRT/100

X=XR(8)/100

R=X*100/X*8

R=100/8

R= 12.5

So the Rate of interest is 12.5%
