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.
