$\dfrac{p_1V_1}{T_1}=\dfrac{p_2V_2}{T_2}$
$\Leftrightarrow \dfrac{p_1V_1}{T_1}=\dfrac{\frac{1}{5}p_1+p_1.V_1-\frac{1}{10}V_1}{T_1+16}$
$\Leftrightarrow \dfrac{p_1V_1}{T_1}=\dfrac{\frac{6}{5}p_1.\frac{9}{10}V_1}{T_1+1}$
$\Leftrightarrow \dfrac{1}{T_1}=\dfrac{\frac{27}{25}}{T_1+16}$
$\Rightarrow T_1=200K$
