. In a test for a fault to earth on a 500 m length of cable having a resistance of 1 ohm per 1000 m, the faulty cable is looped with a sound cable of the same length but having a resistance of 2.25 per 1000 m. The resistance of the other two arms of the testing network at balance are in the ratio 2.75:1. Calculate the distance of the fault from the testing end of the cable.

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
