An audio signal consists of two distinct sounds : one a human speech signal in the frequency band of $200\; Hz$ to $2700\; Hz$, while the other is a high frequency music signal in the frequency band of $10200\; Hz$ to $15200\; Hz$. The ratio of the AM signal bandwidth required to send both the signals together to the AM signal bandwidth required to send just the human speech is :
