Can anyone tell me that if I use 2 languages ââin the article, will there be any problem in taking AdSense? I mean that if I write the title in English and the rest of the article in Hindi Or some words in the title in Hindi and some words in English which are important because they are keywords.
Publisher policy says primary content of article should be in supported language.
Note: Placing Google ad code on pages with content primarily in an unsupported language is not permitted by the Google Publisher Policies.

As long as the language mixture is natural, I think you should be fine.
For example, not every word can be translated to every language, like “file”, “internet”, etc. so using more than one language is sometimes unavoidable.
That’s ~ my opinion and interpretation, but there is also consensus that keyword manipulation / stuffing, click baiting, etc., would make your content non-monetizable.
