There were originally 325 students in the fifth grade. In the new semester, the number of boys increased by 25, and the number of girls decreased (1/20). As a result, the total number of students increased by 16. I would like to ask: How many boys are there?
五年级原来有学生325人，新学期男生增加25人，女生减少了(1/20)，结果总人数增加了16人．请问：现有男生多少人？
