If in the sales department of a company, the average salary per employee is Rs. 350, average salary of 10 senior employees is Rs. 450 per employee and the average salary of the remaining staff is Rs. 250 per employee, then what is the total number of employees working in the sales department?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 20.
Let the total number of employees in the sales department = x
⇒ 4500 + 250x - 2500 = 350x
⇒ 100x = 2000
⇒ x = 2000/100 = 20
