Question:

Options:

28

30

29

27

Correct Answer:

30

Explanation:

Let the number of employees be x

Total salary = 14000x

Total salary of 5 technicians = 18000 x 5 = 90000

Total salary of rest of the employees = 13200(x - 5) = 13200x - 66000

⇒ 14000x = 13200x - 66000 + 90000

⇒ 14000x - 13200x = 90000 - 66000

⇒ 800x = 24000

⇒ x = 30

The total number of workers in the factory is 30.
