To Find :-

• Mean of the Salary of 60 workers in Factory.

Explanation :-  

In order to find the Mean of the above Data, we need find the $\bf \sum f_i x_i$ of the Data by making an Table.

$\textcopyright \: \: \begin{array}{| c | c | c |} \cline{1-3} \rm Salary \: (x_i) & \rm Number \: of \: Workers \: (f_i) & \rm f_ix_i \\ \cline{1-3} 3000 & 16 & 48000 \\ \cline{1-3} 4000 & 12 & 48000 \\ \cline{1-3} \cline{1-3} 5000 & 10 & 50000 \\ \cline{1-3} 6000 & 8 & 48000 \\ \cline{1-3} 7000 & 6 & 42000 \\ \cline{1-3} 8000 & 4 & 48000 \\ \cline{1-3} 9000 & 3 & 27000 \\ \cline{1-3} 10000 & 1 & 10000 \\ \cline{1-3} \bf Total & \bold{\sum f_i = 60} & \bold{\sum f_ix_i = 305000} \\ \cline{1-3} \end{array}$

Now Finding the Mean of Data,

$\rm : \: \implies \bar{x} \: (Mean) = \dfrac{\sum f_ix_i}{\sum f_i}$

$\rm : \: \implies \dfrac{305000}{60} \: \: R_S$

$\red { \boxed { \bf : \: \implies 5083.33 \: \:R_S}}$

Hence, the mean of the Data is 5083.33 Rs.
