Question

3. Of the 80 students in class, 25 are studying German, 15 French and 13 Spanish. 3 are studying German

and French; 4 are studying French and Spanish; 2 are studying German and Spanish, and none is studying
all 3 languages at the same time. How many students are not studying any of the three languages?​

Answer 1

25 + 15 + 13 + 3 + 4 + 2 = 40 + 16 + 6 = 62

80-62=18

18 are left so 18 are not studying any languages.

Hope this helps
