50 students passed in English
60 students passed in Mathematics
40 students passed in both subjects
None of them fail in both the subjects
number of students passed at least in one of the subjects = (number of students passed in English) + (number of students passed in Mathematics) - (number of students passed in both subjects)
number of students passed in at least in one of the subjects = 50 + 60 - 40 = 110 - 40 = 70
Hope this helps!
