Answer» LET TOTAL workers in a workshop be N. Given, Total monthly salary of workers in a workshop = 8500N Given, Total salary of 7 technicians = 7 × 10000 = 70000 Total REMAINING workers = N – 7 Total salary of remaining workers = 7800 × (N – 7) Then, ⇒ 8500N = 70000 + 7800 × (N – 7) ⇒ 8500N = 70000 + 7800N - 54600 ⇒ 700N = 15400 ⇒ N = 22 ∴ Total NUMBER of workers is 22. |
