Answer 2

Given,

Group $\[ = A,B,C,D\]$

Group Index $\[ = 100,120,130,110\]$

Weight $\[ = 3,1,4,2\]$

Solution,

Put the given data in tabled form,

Consumer price index,

$\[ = \frac{{\sum {\left( {Group\,index \times weight} \right)} }}{{total\,weight}}\]$

Put the values in the formula,

$\[ = \frac{{300 + 120 + 520 + 220}}{{10}}\]$

Solve it,

$\[ = \frac{{1160}}{{10}}\]$

Simplify it,

$\[ = 116\]$

Hence, the consumer price index number is $\[ 116\]$.
