Explanation

If 2/3 of the class of 60 are girls (=40), 1/3 must be boys (=20)
2/5 of the class (=24) are taking music.
The maximum number of girls not taking music will be when all the boys take music.
If all 20 boys take music, then only 4 girls need to take it, so 36 girls do not take music lessons.
