你的句子加不加定冠词都可以。因为当 all后接“数词+复数名词”时，加不加the都表示特指（但从使用的实际情况来看，the多半是省略的）。又如：
All (the) 100 senators agree to a postponement. 100位议员全都同意延期。
The plane crashed, killing all (the) 200 people aboard. 飞机失事，机上 200 人全部遇难。
I speak for all (the) 7,000 members of our organization. 我代表本组织的 7,000 名成员发言。
All (the) 140 guests were brought out of the building safely by firemen. 消防队员把 140 名客人全部从大楼里安全营救出来。
All (the) 155 passengers died instantly when the plane slammed into the mountain. 飞机一头撞到山上，155 名乘客顷刻间全部丧生。
All (the) 2500 employees went on strike in protest at the decision to close the factory. 2500名员工全部参加了罢工，以抗议关闭工厂的决定。
