Total number of songs in Julie's MP3 player = 860
Percentage of rap songs in Julie's MP3 player = 20%
Then
Number of rap songs in Julie's MP3 player = (20/100) * 860
   = 860/5
   = 172
Percentage of R&B songs in Julie's MP3 player = 15%
Then
Number of R&B songs in Julie's MP3 player = (15/100) * 860
      = 1290/10
   = 129
So
The number of other types of songs in Julie's MP3 player = 860 - (172 + 129)
   = 860 - 301
   = 559
So the number of other types of songs in Julie's MP3 player was 559.
