Mean of the given data

= \frac{8 + 12 + 16 + 22 + 10 + 4}{6}

= \frac{72}{6} = 12

New mean = Original mean + 25% of original mean

\Rightarrow

New mean = 12 + 25 %of 12

\Rightarrow

Mean mean = 12 +

\frac{25}{100}

x 12

\Rightarrow

Mean mean = 12 +

\frac{1}{4}

x 12

\Rightarrow

Mean mean = 12 + 3

\Rightarrow

Mean mean = 15
