There are a total of 60 students in a class and the ratio of the number of boys to that of the girls is 4 : 1, respectively. If 22 of the boys from this class are vegetarians, then find the number of non-vegetarian boys from the same class .
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 26
Explanation :
Let the number of boys and girls in the class be 4x and x respectively.
According to the given question,
⇒ 4x + x = 60
⇒ 5x = 60
⇒ x = 12
Hence the number of boys = 4x = 4 × 12 = 48
Number of vegetarian boys = 22
Hence the number of non-vegetarian boys = 48 - 22 = 26.
Hence the number of non-vegetarian boys is 26.
