Answer 1

Total number of students = 100

21 + 20 + 5 = 46

Number of students pass in both subjects = 100 -46 = 54

Answer 2

Total number of students = 100
Total number of students who did not pass in either subject or both = 21+20+5
= 46

Number of students who passed in both the subjects = 100-46
= 54
