    Initially the voltage gain of the amplifier is 100 i.e. A=100.
    Then a negative feedback is applied to the amplifier where the gain of the feedback loop is given as β = 0.04
    Now the overall gain of the negative feedback amplifier is given as, = A/1+Aβ
    = 100/[1+(100)(0.04)]
    = 100/(1+4)
    = 100/5
    = 20
