There is most likely an error in this sentence because the phrase "one 600 pupils" doesn't make sense. No wonder it puzzled you. The writer may have wanted to say, "There are about 600 pupils..." If one wanted to write 1600 pupils, one would write:
There are one thousand six hundred students in this school.
I hope this is helpful.
