The following table represents the total number of students in different classes and the respective number of students who are vegetarian, in a school. Study the table carefully and answer the question that follows.

Class	Total number of students	Number of vegetarian students
XII	150	105
XI	165	100
X	125	80
IX	140	90

What is the percentage of non-vegetarian students in class XII?

Correct option is B

Given:

Total number of students in class XII = 150

Number of vegetarian students in class XII = 105

Number of non-vegetarian students =150 - 105 = 45

Concept Used:

Percentage = $$\left( \frac{\text{Number of non-vegetarian students}}{\text{Total students}} \right) \times$$​100

Solution:

Percentage = $$\left( \frac{45}{150} \right) \times 100$$​

Percentage = (3) × 10 = 30%

students in class XII is 30%.
