This math problem looks a bit messy, and it needs careful analysis to clear the way of thinking. Don't worry, step by step.

Physical education class, Class One, Grade Two. M-girls stood in the first team, one * * * accounted for four pairs, and there was one person left.

The number of girls should be 4×4+ 1, which is equal to 17.

Let's look at the number of boys again. Boys stand in one team for every four people, and there are three people left in the three teams.

Then the number of boys should be 4×3+3 equal to 15.

There are boys and girls. Add them together to get the total number of students in Class One, Grade Two.

That is, 17+ 15=32 people.
