Question

In a class of 200 students, 120 students
take German, and 100 study French. If a
student must study at least one of these
languages, what percent of the students
study French but not German?​

Answer 1

Answer:

40% of the students  study French but not German

Explanation:

120+100 = 220

but given that there are only 200 students in a class.

i.e, 20 students study both languages.

Total no of students studying french -20 students study both languages.

  100-20= 80

   80  ×100 = 40%

   200
