in which city do you expect rusting to be a greater problem-in delhi or in mumbai ?why?
in delhi the rusting would be a greater problem because as we know that rusting requires three major things that are.
1.iron or any other metal
3.moisture or humidity
so as we know that mumbai is surrounded by many water bodies any rusting could happen easily there while as in delhi rusting would be more harder because there is less amount of water or humidity that is nesscesary for rusting.so hence its proved that rusting is harder in delhi and in mumbai it would be more easier
