Voltage amplification (gain) is given by
\mathrm{A=\frac{\mu}{1+\frac{r_p}{R_L}}}
where \mathrm{\mu } is amplification factor, \mathrm{r_{p}} is plate resistance and \mathrm{R_{L}} is load resistance.
\mathrm{\text { Given, } \mu=36, r_P=10000 \Omega, R_L=30000 \Omega}
Putting in the relation, we obtain
\mathrm{A=\frac{36}{1+\frac{10000}{30000}}=\frac{36}{1+\frac{1}{3}}=\frac{36 \times 3}{4}=27}
