Answer:

The mean salary of the workers = Rs4900

Step-by-step explanation:

We have to find the mean of monthly salary of the workers:

Mean salary of the workers =

(5000+ 7000+ 3000+ 4000+ 4000+ 3000+ 3000+ 3000+ 8000+ 4000+ 4000+ 9000+ 3000+ 5000+ 5000+ 4000+ 4000+ 3000+ 5000+ 5000+ 6000+ 8000+ 3000+ 3000+ 6000+ 7000+ 7000+ 6000+ 6000+ 4000) /30

$=\dfrac {147000} {30} = 4900$

So the mean salary of the workers = Rs4900
