Detailed Solution

Let the no. of total student in the class is 100 and number of boy be x
Now, 12% of the 100 is 12
Then, number of girl is x−12.
Total number of student is x+(x−12) =100
Therefore, x = 56
Then, the no. of boys = 56
And no. of girls = 44
Boys:Girls = 56:44 = 14:11
Hence option 3 is correct.
