Answer 2

$\huge{\orange{\boxed{Hey\: mate !}}}$

Average = $\frac{sum \:of \:all \:numbers}{2}$

Average = $\frac{12+5+18+10+0}{2}$

Average = $\frac{45}{2}$

Average = $22.5$

$\pink{\boxed{\underline{Answer \implies 22.5}}}$

$Mean=\frac{sum\: of\: n \:numbers}{n}\\\implies \frac{12+5+18+10+0}{5}\\\implies\frac{45}{5}\\\implies{9}$

$\pink{\boxed{\underline{Answer \implies 9}}}$
