$\huge\boxed{\texttt{\fcolorbox{Red}{aqua}{Hello Friend}}}$

SP = 708.50
profit%= 9%
CP = SP x 100/(100 + Profit%)
$= \frac{708.50 \times 100}{(100 + 9)} \\ = \frac{70850}{109} \\ = 650$
Now
CP = 650
PROFIT % =11%

$sp = cp( \frac{100 + profit\%}{100} ) \\ = 650 \times \frac{(100 + 11)}{100} \\ = \frac{650 \times 111}{100} \\ = 721.50$
So SP is Rs 721.50 Answer
