For a constant collector-emitter voltage of $\displaystyle 8$ V, the collector current of a transistor reached to the value of $\displaystyle 6$ mA from $\displaystyle 4$ mA, whereas base current changed from $\displaystyle 20 \mu \mathrm{~A}$ to $\displaystyle 25 \mu \mathrm{~A}$ value. If transistor is in active state, small signal current gain (current amplification factor) will be :
