Answer the following question based on the information given below.
The proportion of male students and the proportion of vegetarian students in a school are given below. The school has a total of 800 students, 80% of whom are in the Secondary Section and rest equally divided between Class 11 and 12.
âââââââ
In the Secondary Section, 50% of the students are vegetarian males. Which of the following statements is correct?
Answer & solution
- 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.
(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).
