Given,

Average salaries of two groups of employees are Rs. 1175 and Rs. 1325

Number of employees in two groups are 80 and 50.

Solution,

Calculate average of both group.

$\[ = \frac{{1175 \times 80 + 1325 \times 50}}{{80 + 50}}\]$

$\[ = \frac{{94000 + 66250}}{{130}}\]$

$\[ = \frac{{160250}}{{130}}\]$

$\[ = 1232.69Rs.\]$

Hence the average of both group is $\[ 1232.69Rs.\]$
