    The average salary per employee in an office is Rs. 3,200 per month. T...
    Let the number of officers and non-officers be n and m respectively.
    Total salary of officers = 6800n And, Total salary of non-officers = 2000m
    Total salary of all the employees = 6800n + 2000m = 3200(m + n)
    3600n = 1200m
    3n = m
    m = 3 x 5 = 15
    Number of non-officers =15

    The average salary per employee in an office is Rs. 3,200 per month. T...
    Given Information:
    - Average salary per employee in the office = Rs. 3,200 per month
    - Average salary of officers = Rs. 6,800
    - Average salary of non-officers = Rs. 2,000
    - Number of officers = 5

    To Find:
    - Number of non-officers in the office

    Approach:
    - Let the number of non-officers be 'x'
    - We can use the concept of weighted average to solve this problem

    Solution:
    1. Average Salary Calculation:
    - The average salary per employee in the office is given as Rs. 3,200.
    - We can represent this using the formula for average:
    Total Salary / Number of Employees = Average Salary
    Total Salary = Average Salary * Number of Employees

    2. Calculation for Officers:
    - The average salary of officers is given as Rs. 6,800.
    - We know that the number of officers is 5.
    - Using the formula for average, we can write:
    Total Salary of Officers = Average Salary of Officers * Number of Officers

    3. Calculation for Non-Officers:
    - The average salary of non-officers is given as Rs. 2,000.
    - We know that the number of non-officers is 'x'.
    - Using the formula for average, we can write:
    Total Salary of Non-Officers = Average Salary of Non-Officers * Number of Non-Officers

    4. Calculation for Total Salary:
    - The total salary in the office can be calculated by adding the total salary of officers and the total salary of non-officers:
    Total Salary = Total Salary of Officers + Total Salary of Non-Officers

    5. Equating Total Salary Calculations:
    - We can equate the total salary calculated in steps 1 and 4:
    Average Salary * Number of Employees = Total Salary of Officers + Total Salary of Non-Officers

    6. Substituting the Values:
    - We can substitute the given values into the equation from step 5:
    3,200 * (5 + x) = 6,800 * 5 + 2,000 * x

    7. Solving the Equation:
    - Simplifying the equation from step 6:
    16,000 + 3,200x = 34,000 + 2,000x
    1,200x = 18,000
    x = 15

    Answer:
    The number of non-officers in the office is 15.

    The average salary per employee in an office is Rs. 3,200 per month. T...
    Let total no. of employees be n.
    given average = 3200
    3200=(5x6800+(n-5)×2000)/n

    3200n=34000+2000n-10000

    3200n-2000n=24000
    1200n=24000
    n=24000/1200=20

    n-5 is non officer= 20 - 5 = 15
