Question

9. Robert deposited Rs. 12500 in a bank for 3 years. After three years, he received Rs.
15500 from the bank as the amount. What is the rate of interest he received from the
bank?

Answer 1

Answer:

Step-by-step explanation:

Principle(P)= Rs. 12500

Time(T)= 3 years

Amount(A)=Rs. 15500

Interest (I)= A-P

                = Rs. 15500-Rs. 12500

                = Rs. 3000

Interest(I)= $\frac{P*R*T}{100}$

3000 = $\frac{12500*R*3}{100}$

     $R=\frac{3000*100}{12500*3}$

    ∴R=8 percent p.a.
