The average salary of the entire staff in Reliance Company is Rs. 150...
Given Data:
- Average salary of the entire staff = Rs. 15000 per month
- Average salary of officers = Rs. 45000 per month
- Average salary of non-officers = Rs. 10000 per month
- Number of officers = 20
Calculating Total Staff:
Let the number of non-officers be x.
Total salary of officers = Number of officers * Average salary of officers = 20 * Rs. 45000 = Rs. 900000
Total salary of non-officers = x * Rs. 10000
Total salary of the entire staff = Total salary of officers + Total salary of non-officers
Rs. 15000 = (Rs. 900000 + Rs. 10000x) / (20 + x)
Solving the Equation:
Rs. 15000 = (Rs. 900000 + Rs. 10000x) / (20 + x)
15000(20 + x) = 900000 + 10000x
300000 + 15000x = 900000 + 10000x
5000x = 600000
x = 120
Therefore, the number of non-officers in the Reliance company is 120.

The average salary of the entire staff in Reliance Company is Rs. 150...
Given,
The average salary of the entire staff = Rs. 15000
The average salary of officers = Rs. 45000
The average salary of non-officers = Rs. 10000
Number of officers = 20
Let the number of non-officers be x.
Total member in entire staff = x + 20
Total salary of the entire staff =(x+20)×15000
⇒ 15000x + 300000
Total salary of officers = 20 × 45000 = 900000
Total salary of non-officers = x × 10000 = 10000x
Total salary of the entire staff =900000 + 10000x ⋯(2)
From equation (1) and (2)
⇒10000x + 900000 = 15000x + 300000
⇒ 5000x = 600000
⇒ x = 120
Hence, the correct answer is 120.
