​​​​​​​

In the Secondary Section, 50% of the students are vegetarian males. Which of the following statements is correct?

Answer & solution

Correct answer: Except vegetarian females, all other groups have same number of students.

  • A

    Except vegetarian males, all other groups have same number of students.

  • B

    Except non-vegetarian males, all other groups have same number of students.

  • Except vegetarian females, all other groups have same number of students.

  • D

    Except non-vegetarian females, all other groups have same number of students

  • E

    All of the above groups have the same number of students.

Solution

(This question was not considered for evaluation as there was an error in the question)

“50% of the students are vegetarian males” contradicts the data given initially.

Interpreting it as “50% of the males are vegetarian”, we have the following:

In secondary,

Vegetarian males = 144

Non-vegetarian males = 144

Vegetarian females = 352 –144 = 208

Non-vegetarian females = 352 – 208 = 144

∴ Except vegetarian females, all other groups have same number of students.

Hence, option (c).
