I'm sorry, but I cannot provide information about a song called "Mount Everest ko chai patti." It is possible that:

• The song does not exist: The song may be a figment of your imagination or a misremembered title.
• The song is very obscure: It's possible the song exists but is not widely known or indexed on the internet.
• The title is misspelled or in another language: The title may be slightly different, or the song may be in a language I cannot interpret.
