When the Wheatstone bridge shown in the figure is used to find the value of resistor $R_{X}$, the galvanometer $G$ indicates zero current when $R_{1}=50\Omega, R_{2}=65\Omega$ and $R_{3}=100\Omega$. If $R_{3}$ is known with $±5$% tolerance on its nominal value of $100 \Omega$ , what is the range of $R_{X}$ in Ohms?
