In a class of 140 students numbered 1 to 140, all even numbered students opted Mathematics course, those whose number is divisible by 3 opted Physics course and those whose number is divisible by 5 opted Chemistry course. Then the number of students who did not opt for any of the three courses is

Text Solution

Verified by Experts


Number of student opted for mathematics = 70 = M
Number of students opted for physics = 46 = P
Number of student opted for chemistry = 17 = C
M = 70
P= 46
C = 17
Number of students who didn't opt for any = 47
