\mathrm{R_{\text {input }}=200 \Omega} \\

\mathrm{R_{\text {output }}=60 \Omega} \\

Slope  \mathrm{=\frac{\Delta I_{C}}{\Delta I_{B}}=\frac{1}{20} \times 10^{3} }\\

Voltage Gain  \mathrm{\left(A_{1}\right)=\frac{\Delta I_{C}}{\Delta I_{B}} \times \frac{R_{0}}{R_{i}}} \\

                              \mathrm{=\frac{1000}{20} \times \frac{6}{20}} \\

Voltage Gain \mathrm{=15}
