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

559 might be the answer

Answer 2

20% of 860 Songs are Rap,

$= \frac{20}{100} \times 860 \\ = \frac{1}{5} \times 860 \\ = 172 \: songs.$

15% of Songs are R&B,

$= \frac{15}{100} \times 860 \\ = \frac{3}{20} \times 860 \\ = \frac{3}{2} \times 86 \\ = 3 \times 43 \\ = 129 \: songs.$

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 !!
