Solution(By Apex Team)

Here We can use formula of CI. $\begin{array}{l} A=P \times\left[1+\left(\frac{r}{100}\right)\right]^{n} \\ A=2100 \times\left[1+\left(\frac{5}{100}\right)\right]^{2} \\ A=2100 \times\left[\frac{105}{100}\right]^{2} \\ A=\frac{2100 \times 11025}{10000} \end{array}$ Hence, Amount $A=R s .2315 .25$
