Answer:

average salary per head of the supervisors a =400

average salary per head of the labors  b = 56

average salary of the company

$60 =\frac{56 \times b +400 \times a} {a+b}\\60a+60b=400a+56b\\4b =340 a\\b =\frac{340 a}{4} \\b= 85 a$

Here number of supervisor is 12

number of the labours in the factory​ = 85 x 12 =1020

number of the labours in the factory​ is 1020
