Let the Number of Songs in the Music Player of Lou be : L
Given that Kelly has 4 times as many songs as Lou has in her Music Player
⇒ The Number of songs in Music Player of Kelly = 4 × L
Given that Tiffany has 6 times as many songs as Lou has in her Music Player
⇒ The Number of songs in Music Player of Tiffany = 6 × L
Given that Altogether have 682 songs in their Music Players
⇒ Tiffany songs + Lou songs + Kelly songs = 682
⇒ 6L + L + 4L = 682
⇒ 11L = 682
⇒ L = 62
⇒ Number of Songs in Music Player of Lou = 62
⇒ Number of Songs in Music Player of Kelly = 4 × L = 4 × 62 = 248
