The resistance of a certain piece of wire is found to be 0.8. Calculating voltage drop of this cable, vd = 0.715 mv/a/m, vd = 0.715 * distance*load current = (0.715/1000)*200*139 =19.877 v the allowable voltage drop = 415 * 5% = 20.75v, this means that the cable is accepted because the voltage drop is in limits (5% = 20.75 v)
