$= let \: interest \: at \: the \: end \: of \: the \: year \: be \: = x \\ ratio \: of \: interest \: to \: principal \: in \: two \: ways$

$\frac{x}{6050} \times 6050 \: \: = \frac{65}{100} \times 6050$

$x = \frac{65 \times 6050}{100} = \frac{393250}{100} = rs3932.5 \: is \: t he \: interest \: amount$

$total \: amount \: = principal \: amount + interest \: amount \\ 6050 + 3932.5 = 9982.5 \\ total \: amount \: is \: 9982.5 \\ hope \: this \: help \: you$
