是该问题的答案！！！！！！！！！！

Answer 1

桌子上有8个盒子．盒子里有红气球或者白气球，每个盒子里是不同数字的气球．有7个的，10个的，13个的，18个的，28个的，32个的，46个的，62个的，假设你不知道气球的颜色和数目．现在你取走一个盒子，剩下7个盒子里红气球的数字是蓝气球的两倍．请你找出你取走的是哪个盒子

偶数学白痴 做不出来 就翻译的一下

Answer 2

The answer is 62.

After you took out one ball the total number has to be dividable by 3 because red balls are 2 times as the blue balls.

consider what left by dividing 3 for all these numbers: 7 (1); 10 (1); 13 (1); 18 (0); 28 (1); 31 (1); 46 (1); 62 (2). You have to take 62 off so that the sum is dividable by 3.

If you really want to know what is red and what is blue, the answer is not clear because there are two possibilities:
A: red:10, 18, 28, 46; blue: 7, 13, 31
B: red:7, 18,31, 46; blue:10, 13, 28

Answer 4

至少有2名同学得了满分.理由如下:
由题意可知,答错第一题的有1人,答错第二题的有5人,答错第三题的有4人,答错第四题的有8人.所以这次数学竞赛最多有1+5+4+8即18名同学没有得满分.那么至少有2名同学得了满分.
