Answer 2

Given that,

The table show the daily expenditure on grocery of 25 household in a locality.

According to figure,

We need to calculate the model daily expenditure on grocery

Using formula of model

$model =l+\dfrac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}}\times h$

Where, l = lower limit of modal class

h = class interval

f₁ = frequency of modal class

f₀ = frequency of the class before modal class

f₂ = frequency of the class after modal class

Put the value into the formula

$model = 200+\dfrac{12-5}{2(12)-5-2}\times50$

$model =220.5$

Hence, The model daily expenditure on grocery is Rs 220.5
