Answer 2

$\boxed{ Answer = Rs\:6000}$

Explanation = Let principal be Rs 100,

Rate = 5% , Time = 2 years.

Simple Intrest =

$\frac{Principal \times Rate \times Time}{100} = \frac{100 \times 5 \times 2}{100} = Rs \: 10/-\: \\ \\ compound \: intrest \: = 100 [\frac{105}{100} \times \frac{105}{100} - 1] \\ \\ = 100 \times [ \frac{11025}{10000} - 1] = Rs \: 10.25 \\\\ Difference \: in \: both \: intrest \: = Rs \: 10.25 - 10 \\ = Rs \: \frac{25}{10} \: but \: the \: \: given \: difference = Rs \: 25 \ \ \\ if \: the \: difference \: is \: Rs \: \frac{25}{100} then \: principal \: is \: = Rs \: 100 \\and \: if \: the \: difference \: is \: Rs \: 15 \: then \: principal \: is = \:Rs = 100 \times \frac{100}{25} \times15 = Rs \: 6000$

____________________________________________

Simple intrest = $\frac{Principal \times \: Rate \times Time}{100}$

Compound Intrest =Principal$[(1+ \frac{rate}{100})^{Time} - 1] \\\\or \: Amount \: -Principal$
