Earlier, Delhi's chief electoral officer Vijay Dev said he expected the final percentage of voting to be between 70 and 75 per cent.
There were reports of malfunctioning of electronic voting machines (EVM) in some parts of the city but they were rectified, election officials said.
Election officials had to replace a total of 112 EVMs because of malfunctioning.
The EVM at polling booth in Aurangazeb Lane, where Rahul Gandhi cast his vote, malfunctioned when polling began.
People in many polling booths in Tuglaqabad, Karol Bagh, Trilokpuri and Badarpur said they had to wait for a long time to cast their votes as electronic voting machines were not working.
