উত্তর:
960
Let the number of students enrolled at PQR school be x
x/12 students were absent
So, 11x/12 students were present
number of students went on a field trip = 11x/12 * 1/5 = 11x/60
Number of students who were absent or went on a field trip = x/12 + 11x/60 = 16x/60 = 4x/15
Number of students staying in the school = x - 4x/15 = 11x/15
ATQ,
11x/15 = 704
∴x = 960
ans: 960
