re: Electrician Estimate Question - Help with a list of jobs

I had a private home inspector (also an EE) tell me that if you ran a jumper from the ground screw to the neutral it would meet code for those 3 prong outlets since there was no ground wire. This was on a 70 year old house my son was looking at where the building codes are generally pretty rigid. Otherwise they would have to be replaced with 2 prong outlets. Since he didn't buy the house, I'm not sure it that would have passed inspection or not.
