Gọi số công nhân ở phân xưởng 1 là xx, khi đó số công nhân ở phân xưởng 2 là 220−x220−x.
Số công nhân sau khi chuyển ở phân xưởng 1 và 2 lần lượt là x−10x−10 và 230−x230−x
Lại có 2/3 số công nhân phân xưởng 1 bằng 4/5 số công nhân phân xưởng 2 nên ta có
23(x−10)=45(230−x)23(x−10)=45(230−x)
<−>10(x−10)=12(230−x)<−>10(x−10)=12(230−x)
<−>22x=2860<−>22x=2860
<−>x=130<−>x=130
Vậy số công nhân ở phân xưởng 1 là 130, số công nhân ở phân xưởng 2 là 90.
