Given below is the plot of the molar conductivity vs concentration for KCl in aqueous solution. If, for the higher concentration of KCl solution, the resistance of the conductivity cell is 100 , then the resistance of the same cell with the dilute solution is ' x ' The value of x is __________ (Nearest integer)
