120 students total. 60% speak French = 72. Of those who speak French, 25% also speak English = 18 (this will be the BOTH bucket)
Total = Group A (French) + Group B (English) - Both (French and English)
120 = 72 + Group B (English) - 18
120 = English + 54 *subtract out the 54 from both sides*
66 = English
Answer is C - 66
Total = Group A (French) + Group B (English) - Both (French and English)
120 = 72 + Group B (English) - 18
120 = English + 54 *subtract out the 54 from both sides*
66 = English
Answer is C - 66
