During the military training, the students of all grades had lunch together. The instructor calculated that if there were 6 people per table, there would be 22 people left without a landlord to sit. When I was seated, I found that 3 tables were broken, so I changed to sit at each table. 8 people, if there are 6 people left, there is no place to sit. May I ask: How many people are there in the whole grade?
军训时全年级的同学一起吃午饭，教官算了一下，如果每张桌子坐6人，那么还剩下22人没地主坐，入座时发现有3张桌子坏了，于是改为每张桌子坐8人，如果还剩下6人没地方坐．请问：全年级一共有多少人？
