Option 4 : 2640 kg
Let the number of workers in company B be x.
So, the number of workers in company A = x × 80/100 = 4x/5
Also, let the average weight of workers of company B be y.
So, the average weight of workers of company A = y × 150/100 = 3y/2
According to the question:
+ = 4840
(6xy/5) + xy = 4840
11xy/5 = 4840
xy = 2200
The total weight of workers of company B = xy = 2200 kg
So, the total weight of workers of company A = 4840 - 2200 = 2640 kg
