Answer:

S.I. = Rs. (15500−12500)=Rs.3000

SI= P.N.R/100

Rate = 100×3000/12500×4%=6%

Answer:

The rate of interest is 6.4%

Step-by-step explanation:

Given : Principal (P) = Rs. 12500  

          Total amount (A) = Rs. 16500

          The time period (t) = 5 years

To find : Rate of interest (R) = ?

Solution :

  • It is given that Principal (P) = Rs. 12500

         Total amount (A) = Rs. 16500  

         The time period (t) = 5 years  

  • We have to find rate of interest (R).
  • We know the formula for simple interest as,

        S.I. = A-P

              = 16500-12500

              = Rs. 4000

  • Now, to find rate of interest, use the formula for simple interest as

            S.I. = \frac{P*R*t}{100}

           ∴ 4000=\frac{12500*R*5}{100}

           ∴ 4000*100 = 62500*R

              ∴  400000 = 62500*R

                     ∴  R=\frac{400000}{62500}

                        ∴  R=6.4%                          

  • ∴  The rate of interest is 6.4%.
