Let the required number of non–officers = x
200x + 520 x 15 = 250 (15 + x)
250x – 200x = 520 * 15 – 250 x 15
50x = 4050
x = 81

The average salary of the entire staff in an office is Rs 250 per mont...
Understanding the Problem:
The problem states that the average salary of the entire staff in an office is Rs 250 per month, with officers earning an average of Rs 520 and non-officers earning an average of Rs 200.
Calculating the Average:
Let the number of officers be \( x \) and the number of non-officers be \( y \).
Based on the given information, we can create the following equations:
1. \( 520x + 200y = 250(x + y) \) (since the average salary of the entire staff is Rs 250)
2. \( x + y = Total Staff \)
Solving these equations, we get:
\( 270x = 50y \)
\( x = 5y/27 \)
Comparing Quantity I and Quantity II:
Quantity I: Number of Officers = 15
Quantity II: Number of Non-Officers
If we substitute the value of officers in terms of non-officers from our calculation above into Quantity I, we get:
\( 5y/27 = 15 \)
\( y = 81 \)
Hence, the number of non-officers is 81. Therefore, Quantity II is greater than Quantity I as the number of non-officers is 81, which is greater than 15 (number of officers).
Therefore, the correct answer is option B.
