Xiaohua attended a week-long summer camp, with five people in one room, three people in the last room and a table for nine people for dinner. The last table is

So, first make sure that the mantissa of 3 and 8 is between 200.

Then after dividing the white 9, the mantissa of 8 only adds 98 and 188.

(Because there are 9 people at each table, there are 8 people left, that is, after being divisible by 9, there are 8 left, so out of 200, only 98 and 188 match. )

The same is true in the back.

After dividing the white 9, adding 8 is the mantissa of 3, 53, 143.

After dividing white 7, the mantissa of 8 plus 6 is 48 and 188.

After dividing white 7, the mantissa of 3 plus 6 is 77, 147.

That's obvious. After I divide, the mantissa of adding 3 will never be the mantissa of 7.

So, the answer is just the mantissa of 8.

That only 188 is the final answer of three groups of numbers within 200.

Room allocation: 37 rooms and 3 extra rooms.

Eating: There are 8 extra rooms in 20 rooms.

Grouping: 26 rooms plus 6 rooms.

Final answer 188
