In a class of 30 students, 15 students have taken computer science but not electronics, find the number of students who have taken electronics but not computer science. Note: For students in the class of 30, either computer science or electronics is compulsory. Correct Answer 15

Given:

Total number of students = 30

Calculation:

Students have taken Computer science = 15

Students have taken Electronics = 30 - 15 = 15 

∴ 15 have taken electronics but not computer science.
