• According to given question :

\begin{gathered} \bold{As \: we \: know \: that} \\ \tt: \implies A = P + S.I \\ \\ \tt: \implies 750 = 500 + S.I \\ \\ \green{\tt: \implies S.I = 250 \: rupees} \\ \\ \bold{Simple \: interest \: for \: t_{1} \: time} \\ \tt: \implies S.I = \frac{p \times r \times t_{1} }{100} \\ \\ \tt: \implies 250 = \frac{500 \times r \times 50}{12 \times 100} \\ \\ \tt: \implies 250 =20.8333333333r \\ \\ \tt: \implies r = \frac{250}{20.8333333333} \\ \\ \green{\tt: \implies r = 12\%} \\ \\ \bold{S.I \: for \: t_{2} \: time} \\ \tt: \implies S.I = \frac{p \times r \times t_{2} }{100} \\ \\ \tt: \implies S.I = \frac{500 \times 12 \times 3}{100} \\ \\ \tt: \implies S.I = 180 \: rupees \\ \\ \bold{For \: amount : } \\ \tt: \implies Amount = p + S.I \\ \\ \tt: \implies Amount = 500 + 180 \\ \\ \green{\tt: \implies Amount =680 \: rupees}\end{gathered}

Asweknowthat

:⟹A=P+S.I

:⟹750=500+S.I
