Answer 1

$\huge\boxed{\texttt{\fcolorbox{red}{aqua}{Hey Mate!!!}}}$
$<b><i><font face=Copper black size=4 color=blue>$
Here is your answer

Average of 10 Numbers =
$= \frac{46 + 52 + 48 + 11 + 40 + 62 + 44 + 53 + 96 + 98}{10} \\ \\ = \frac{550}{10} \\ \\ = 55$
Therefore Average is 55

Good marks is 98 As it is highest score out of 100

$\large{\red{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\underline{\underline{\underline{Hope\:it\:helps\: you}}}}}}}}}}}}}}}$

$\huge\boxed{\texttt{\fcolorbox{Red}{yellow}{Be brainly!!!}}}$
