AI explanation

Based on the 4 to 6 ratio, there are 20 boys and 30 girls in the batch. The total marks of the entire batch are 50 students times 62, which equals 3100, and the total marks of the girls are 30 times 60, which equals 1800. The total marks of the boys are 3100 minus 1800, giving 1300. Dividing the boys' total marks by 20 gives an average of 65.
