Resistance of a conductivity cell (cell constant $129 \;m ^{-1}$ ) filled with $74.5\; ppm$ solution of $KCl$ is $100\; \Omega$ (labelled as solution 1). When the same cell is filled with $KCl$ solution of $149 \;ppm$, the resistance is $50\; \Omega$ (labelled as solution 2). The ratio of molar conductivity of solution $1$ and solution $2$ is i.e. $\frac{\wedge_{1}}{\wedge_{2}}=x \times 10^{-3}$. The value of $x$ is
