Question

Julie's MP3 player contains 860 songs. If 20% of the songs are rap songs and 15% of the songs are R&B songs, how many of the songs are other types of songs?

Answer 1

20% of 860 Songs are Rap,


`= (20)/(100) * 860 \\ = (1)/(5) * 860 \\ = 172 \: songs.`

15% of Songs are R&B,


`= (15)/(100) * 860 \\ = (3)/(20) * 860 \\ = (3)/(2) * 86 \\ = 3 * 43 \\ = 129 \: songs.`

860-(Rap+R&B) = Other Types.
860-(172+129) = Others
860-301 = Others
559 = Others.

There are 559 some of other types.

!! Hope It Helps !!
