There were 600 students in a school. Each offered either English or Hindi or both. If 75% offered English and 45% Hindi, How many offered both? Answer: 120

Let: Total students = 600 Students offering English = 75% of 600 = 450 Students offering Hindi = 45% of 600 = 270 Students offering both = x Using the principle of inclusion-exclusion: English+Hindi−Both=Total 450+270−x=600 720−x=600 x=720−600=120 So, 120 students offered both English and Hindi.
