Answer in detail. There are 30 students in the class. If the girls in the class collect 3 kg of waste paper and the boys collect 5 kg of waste paper, a total of 122 kg of waste paper is collected in the class. How many boys and girls are there in the class?

This is a math problem that can be solved by using a system of equations. Let x be the number of boys and y be the number of girls. Then we have:

x + y = 30 5x + 3y = 122

We can solve this system by using substitution or elimination methods. For example, by using substitution, we can get:

y = 30 - x 5x + 3(30 - x) = 122 2x + 90 = 122 2x = 32 x = 16

Therefore, there are 16 boys and 14 girls in the class.
