Answer 1

Average = sum/ total number of observations

Here, average of salary of workers = Rs 7650
Number of workers = 20

7650 = sum/20
Sum = Rs 153000

Now average after manager's salary was added = Rs 8200
Now total number of people = 21
8200 = sum/21
sum = Rs 172200

Manager's salary per month = 172200 - 153000 = Rs 19200
