In how much time would the compounded amount become Rs.9,261 from a principle of Rs.8,000 if the interest is compounded annually at a rate of 5% interest. |

Answer» <P>A = Rs. 9261 P = Rs. 8000 R% = 5% A = P * (1 + (R/100))^T 9261 = 8000 (1 + (5/100))^T 9261/8000 = (105/100)^T 9261/8000 = (21/20)^T (21^3)/(20^3) = (21/20)^T (21/20)^3 = (21/20)^T Thus, T = 3 Years |
