Amt get doubled so, SI=Principle
SI=P=(P×12.5×T)/100
T=100×10/125=8 Years
it is the required ans

i cant understand
could you please help me to get this well
if the amount get doubled, it means the interest earned equals to principle amt which is invested
let u invested rs 100 and at last u got rs 200, it means u earned interest of rs 100
hope u understand !
i didint understand the part where you said that s.i=principial
i kmow youre going to say that how silly questions im asking
no, its ok!
thank you

Given rate of interest = 12 1/2% = 25/2.
Let the Simple interest and principal = x.
We know that SI = PTR/100
T = SI * 100/P * R
= x * 100/x * 25/2
= x * 100 * 2/x * 25
= 8 years.
Therefore the sum becomes double in 8 years.
Hope this helps!
