Answer
$ \text { Average rainfall for } 5 \text { years } =\frac{\text { sum of annual rainfall in five years }}{\text { number of years }}$
$=\frac{900+650+450+733+400}{5}$
$=\frac{3133}{5}$
$=626.6$
$\therefore$ The average rainfall in Vidarbha for $5$ years was $626.6 \mathrm{~mm}$.
$=\frac{900+650+450+733+400}{5}$
$=\frac{3133}{5}$
$=626.6$
$\therefore$ The average rainfall in Vidarbha for $5$ years was $626.6 \mathrm{~mm}$.
