The following table shows the income of farmers in a grape season. Find the mean of their income.

Answer

The mean of the income is Rs. `52,5000`.

Explanation

Let us use 'Assumed Mean method '.
Take assumed mean A = 55.

`bard = (Sigma f_(i)d_(i))/(Sigmaf_(i)) = (-210)/(84) = 0 2.5`
Mean `barX = A + bard`
` = 55 + (-2.5)`
` = 55 - 2.5`
` = 52.5` thousand = 52500
