Question 61
Rani invested a sum of ₹800 in a post office for 3 years at 5% compound interest, How much will she get at the end of 3 years
Solution
Principal sum = Rs. 800
Rate of interest = 5% for 3 years
Amount under compound interest = $$P(1+\frac{r}{100})^T$$
= $$800\times(1+\frac{5}{100})^3$$
= $$800\times(\frac{21}{20})^3$$
= $$\frac{9261}{10}=Rs.$$ $$926.10$$
=> Ans - (C)
