Answer: (3) Both classes have equal percentage of students getting first class.

Explanation:-
The total number of students in X class = 30
the number of first class pass students = 24
Then, the percentage of first class students = 24 x 100/30
= 8 x 10
= 80 %

The total number of students in Y class = 35
The number of first class pass students = 28
Then, the percentage of first class students = 28 x 100/35
= 4 x 100/5
= 4 x 20
= 80%

Then,  the Both classes have equal percentage of students getting first class.

Hence, the answer is (3) Both classes have equal percentage of students getting first class
