कितने वर्ष में कोई धन 8 प्रतिशत वार्षिक
साधारण ब्याज की दर से दोगुना हो जायेगा?
In what time will a sum of mon
double itselt at 8% simple
interest?​

Answer 1

Answer:

9 years

Step-by-step explanation:

Let the principal be x

So, Amount = Double of principal = 2x

Rate of interest = 8%

Formula :  

       A =  P ( 1+r )^t

       2x = x (1+0.08 )^t

       2 = (1+0.08)^t

       t = 9.006

       t ~ 9 years

So, a sum of money double itself at 8% p.a in 9 years.
