In a test for a fault to earth on a 600 m length of cable having a resistance of 18 per 1000 m. the faulty cable is looped with a sound cable of the same length but having a resistance of 2.35 per 1000 m. The resistance of the other two arms of the testing network at balance are in the ratio 2.45: 1. Calculate the distance of the fault from the testing end of the cable.
