Non-vegetarian Females in Class 12 = 0.25 * 32 = 8

Vegetarian Males in class 12 = 48 – 8 = 40

Non-vegetarian Males in class 12 = Non-vegetarian in class 12 – Female non-vegetarian in class 12

= 32 – 8 = 24

Required difference = 40 – 24 = 16

From the table given in the question,

Total student = 800

Students in Secondary = 0.8 * 800 = 640

Students in Class 11 = (800 – 640)/2 = 80

Student in Class 12 = 80

Females in Class 11 = 0.55 * 80 = 44

Females in Class 12 = 0.6 * 80 = 48

Females in Secondary = 0.475 * 800 – 44 – 48 = 288

Non-vegetarian in Class 11 = 0.5 * 80 = 40

Non-vegetarian in Secondary = 0.55 * 640 = 352

Non-vegetarian in Class 12 = 800 * 0.53 – 40 – 352 = 32

The percentage of non-vegetarian in class 12 = 32 * 100/80 = 40%
