Answer 2

$\huge\bold\red{Solution :\longrightarrow}$

$\mathsf{Given,}$

$\mathsf{Amount = Rs \: \: 6372}$

$\mathsf{Time = 3 \: years}$

$\mathsf{Rate = 6\% \: \: p.a.}$

$\mathsf{Let \: \: the \: \: principal \: \: be \: \: Rs \: \: P.}$

$\mathsf{Amount = Principal + SI} \\ \\ \mathfrak{= > 6372 = p + ( \frac{p \times 6 \times 3}{100} ) }\\ \\ \mathfrak{= > 6372 = p + \frac{9p}{50} }$

$\mathfrak{ = > 6372 = \frac{50p + 9p}{50}} \\ \\ \mathfrak{= >59p = 6372 \times 50}$

$\mathfrak{ = > p = \frac{6372 \times 50}{59}} \\ \\ \mathfrak{= > p} \mathsf{= Rs }\: \: \mathfrak{5400}$
