Answers (1)
S safeer

Total number of students applied= 150-20=130

130= Number of students applied for the group I + Number of students applied for group II - number of students applied for the both

There fore 

number of students applied for both groups = Number of students applied for the group I + Number of students applied for group II-130=95+82-130=47
