$\huge\fcolorbox{yellow}{red}{ANSWER}$

$given, \: p = 125000, \\ as \: compounded \: quarterly = \frac{8}{4} = 2\% \\ time = 9month = \frac{9}{12}years = \frac{9}{12} \times 4 \\ we \: know \: amount \: = a = (1 + \frac{r}{100} )^{n} \\ a = 125000 [1 + ( \frac{2}{3} ) ]^{3} = rs.132651 \\ c.i \: \: [132651 - 125000] = rs.7651$
