To find the average wage of the 10 workers, follow these steps:
1. List the Wages:
The wages given are:
- Rs. 200
- Rs. 150
- Rs. 220
- Rs. 250
- Rs. 120
- Rs. 100
- Rs. 90
- Rs. 220
- Rs. 250
- Rs. 300
2. Calculate the Total Sum of Wages:
Add all the wages together to get the total sum.
```
200 + 150 + 220 + 250 + 120 + 100 + 90 + 220 + 250 + 300 = 1900
```
So, the total sum of the wages is Rs. 1900.
3. Count the Number of Workers:
The number of workers given is 10.
4. Compute the Average Wage:
Divide the total sum of the wages by the number of workers to find the average wage.
```
Average Wage = Total Sum of Wages / Number of Workers
Average Wage = 1900 / 10
Average Wage = 190
```
Therefore, the average wage of the 10 workers is Rs. 190.
