Verified Answer
The average salary per head of all employees of a company is Rs. 600. ...
Total no. of workers be x
Their average salary = Rs 600
Total salary of all workers = 600x
Average salary of 120 officers = Rs 4000
Total salary of 120 officers = 120 x 4000 = Rs 48000
Average salary of rest of employees = Rs 560
Total salary of these rest of employees = (x - 120)x560
⇒ (x - 120)x560 + 48000 = 600x
⇒56x - 672 + 4800 = 600x
⇒ 4x = 4184
⇒ x = 10320
Total number of workers in the factory = 10320

The average salary per head of all employees of a company is Rs. 600. ...
Given information:
- The average salary per head of all employees of a company is Rs. 600.
- The average salary of 120 officers is Rs. 4000.
- The average salary per head of the rest of the employees is Rs. 560.

To find:
- The total number of workers in the company.

Solution:
Let the total number of workers in the company be N.
Let the total salary of all employees be S.

From the given information, we can write two equations:
1. S/N = 600
2. (120 * 4000 + (N - 120) * 560)/N = 600

Simplifying equation 2, we get:
480000 + 560N - 672000 = 600N
40N = 192000
N = 4800

Therefore, the total number of workers in the company is 4800.

Answer: Option B (10320)
