Spent less n20 5m treat buharis ear infection presidency

I think there may be a few issues with the sentence you've provided.

Firstly, "spent less n20 5m" doesn't make sense. It seems like there's a missing word or a typo. Could you please rephrase or provide more context?

Secondly, "treat buharis ear infection" is a sentence that doesn't seem to be grammatically correct. It appears to be a sentence fragment. Could you please provide more context or clarify what you mean by "Buhari's ear infection"?

Lastly, "presidency" is a noun that refers to the office or position of a president, but it doesn't seem to be related to the previous sentences. Could you please provide more context or clarify what you mean by "presidency"?

If you could provide more information or clarify what you're trying to say, I'd be happy to help you with your sentence!
