According to the question, boys account for 14 of the total number of students, and girls account for 1 1 of the total number of students, that is, there are 56 boys and 44 girls.

Moreover, because the number of participants in Grade 6 1 class is as much as that in Class 62 and Class 63 combined, the number of participants in Class 1 class is 50, and the number of participants in Class 2 and Class 3 is 50.

And because the ratio of the number of boys and girls in each class is; 6 1 class12; 13 shows that there are 24 boys and 26 girls in class 6/kloc-0, so the total number of boys in class 62 and class 63 is 56-24=32, and the total number of girls is 44-26= 18.

So the rest of the boys can only be divided into two parts, one part can be divisible by 5, and the other part can be divisible by 2, so the division of 30+2 is only the following.

20+ 12

10+22

Similarly, girls only have the following four points: 15+3.

12+6

9+9

6+ 12

3+ 15

Because the ratio of boys and girls in Class 6 and Class 3 is 2: 1, only the ratio of 12 to 6 is 2: 1 in the second half of the above-mentioned division, so the ratio of boys and girls in Class 6 and Class 3 is 12 and 6. 5%.

There is another way of thinking, that is, the number of class 62 must be a multiple of 8, and the number of class 63 must be a multiple of 3. Divide 50 into two parts, one is divisible by 8, and the other is divisible by 3, only 32+ 18.

A division.

So the total number of students in Class 6 and Class 3 is 18, and the number of boys is 12.
