Upon looking the table I'm not understood the question.

Answer 1

		Performance		Total
	Average	Good	Excellent
Male	$\color{blue}{16}$	$\color{blue}{22}$	10	$\color{blue}{48}$
Female	$\color{blue}{(40-16) = 24}$	$\color{blue}{8}$	--	32
Total	$\color{blue}{40}$	30	$\color{blue}{10}$	$\color{blue}{80}$

 

$∴\color{green}{\text{The ratio of male to female among average students =}}$ $\color{maroon}{16 : 24 = 2 : 3}$
