Concept: The question tests on Overlapping sets

Solution:

By set theory, Total = Only A + Only B + Only C + (Only A and B) + (Only A and C) + (Only B and C) + All three + Neither 3

Only English = 650, Only Hindi = 550 and Only Marathi = 450. All 3 = 100

Only English and Hindi = English and Hindi - All 3 = 200 - 100 = 100

Only Hindi and Marathi = Hindi and Marathi - All 3 = 400 - 100 = 300

Only English and Marathi = English and Marathi - All 3 = 300 - 100 = 200

Therefore 2800 = 650 + 550 + 450 + 100 + 300 + 200 + 100 + Neither 3

Neither 3 = 2800 - 2350 = 450
