Question

The average of salary of employees in a company is Rs 5000 par month. the average of salary of 5 managers is Rs 6000 and the average salary of workers is Rs 2500. Find the number of workers present in a company?

Answer 1

Let the number of worker be w
A/q
total salary of managers= 5×6000 = Rs 30000
total salary of workers = w× 2500
now, total salary of all employees = (w +5)×5000
                                                       =5000w +25000
so, 5000w +25000 = 30000 + 2500w
⇒2500w = 5000
⇒ w= 2
total number of worker is 2
