The students are divided into 3 + 2 = <<3+2=5>>5 parts where 3 parts are for males and 2 parts are for females.
Each part represents 1000/5 = <<1000/5=200>>200 students.
So, there are 3 x 200 = <<3*200=600>>600 males.
And there are 2 x 200 = <<2*200=400>>400 females.
Hence, 600 x 2/3 = 400 males play basketball.
And 400 x 1/5 = <<400*1/5=80>>80 females play basketball.
A total of 400 + 80 = <<400+80=480>>480 students play basketball.
Therefore, 1000 - 480 = <<1000-480=520>>520 do not like to play basketball.
The percentage of the school that do not like to play basketball is 520/1000 * 100 = <<520/1000*100=52>>52
