An audio signal consists of two distinct sounds : one a human speech signal in the frequency band of $\displaystyle 200$ Hz to $\displaystyle 2700$ Hz, while the other is a high frequency music signal in the frequency band of $\displaystyle 10200$ Hz to $\displaystyle 15200$ 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 :
Official answer
(3)
$\displaystyle 6$
