What is known?

Runs in eight innings.

What is unknown?

Mean Score

Reasoning:

\begin{align}\text{Mean of score}\!=\!\frac{\text{Sum of all runs}} {\text{Number of innings }}\end{align}

Steps:

Total number of innings = $$8$$

Scores of cricketer in $$8$$ innings

\begin{align} = 58,76,40,35,46,45,0,100\end{align}

Mean of score

\begin{align} &= \frac{{\left[ \begin{array}{l}58 + 76 + 40 + 35 +\\ 46 + 45 + 0 + 100\end{array} \right]}}{8}\\ &= \frac{{400}}{8}\\ &= 50\end{align}

Thus, the mean score of a cricketer in $$8$$ innings is $$50.$$
