The ionic conductivity at infinite dilution at $A^{x+}$  and $B^{y-}$ ions are 60 $Sc{m}^{2}mo{l}^{-1}$ and 40 $Sc{m}^{2}mo{l}^{-1}$ respectively. Equivalent and molar conductivity of $A_y{B}_x$ solution of infinite dilution is 40  $Sc{m}^{2}e{q}^{-1}$and 240 $Sc{m}^{2}mo{l}^{-1}$ respectively. The value of  $(\frac{x}{y}\times 4)$
