Answer:

Correct Answer: C

Solution:

According to the question, $ P[ {{( 1+\frac{r}{100} )}^{n}}-1 ]-\frac{P\times r\times t}{100}=63 $

$ \Rightarrow $ $ P[ {{( 1+\frac{5}{100} )}^{2}}-1 ]-\frac{10P}{100}=63 $

$ \Rightarrow $ $ P( \frac{11025-10000}{10000} )-\frac{10P}{100}=63 $

$ \Rightarrow $ $ \frac{1025P}{10000}-\frac{10P}{100}=63 $

$ \Rightarrow $ $ \frac{1025P-1000P}{10000}=63 $

$ \Rightarrow $ $ 25P=Rs.,630000 $

$ \Rightarrow $ $ P=\frac{630000}{25}=Rs.,25200 $
