In hope primary school, there were 325 boys and girls. In the new semester, there were 25 boys and 5 girls, and the total number of students increased by 16? Sixth grade, don't be too complicated
The number of girls is reduced by 25-16 = 9, so the total number of girls is 9 / 5% = 180, so the number of boys is 325-180 = 145. So now the number of boys is 145 + 25 = 170
