Hey mate here is ur answer.

SI = P×R×T/100

448 = x \times8 \times 8 \div 100×12 \\ 448×1200= 64x \\ x = 537600 \div 64 \\ x = 8400
Hope it's help u.

\green{\therefore{\text{Principal=8,400\:rupees}}}\\

\orange{\bold{\underline{\underline{Step-b-step\:explanation:}}}}

 \green{ \underline \bold{Given : }} \\   : \implies  \text{Time (t)= 8 \: months} \\   \\   : \implies  \text{Simple \: interest(S.I) = 448\:rupees} \\   \\   : \implies  \text{Rate(r) = 8\%} \\  \\ \red{ \underline \bold{To \: Find: }} \\  :  \implies  \text{Principal(p) = ?}

• According to given question :

 \bold{As \: we \: know \: that  } \\   \circ \:  \text{Simple \: interest} =  \frac{ \text{Principal }\times \text{ Rate} \times  \text{Time}}{100}  \\  \\  \bold{Putting \: given \: values} \\   : \implies S.I =  \frac{p \times r \times t}{100}  \\  \\   : \implies 448 =  \frac{p \times 8\times\frac{8}{12}}{100}  \\  \\  :  \implies p =  \frac{448 \times 100\times12}{8 \times 8 }  \\  \\  \green{ :  \implies  \text{p = 8400\: rupees}} \\  \\  \green{ \therefore  \text{principal = 8,400\: rupees}} \\  \\   \bold{Basic \: formula\:related\:to\:C.I} \\  \circ \:  A = p(1 +   \frac{r}{100} )^{t}
