Question

in how many years will rs 3,500 amount to rs 4130 at 6% per annum at simple interest

Answer 1

hye

=================================
principal =3500

amount= 4130

s.i = amount - principal

     = 4130 - 3500

     = 630 rs

rate of interst = 6%

lets recall a formula

=>$time = \frac{100*s.i}{p*r}$

                 =$\frac{100*630}{3500*6}$

                  = 63000/21000


                  = 3 years
