Query regarding Undergrad % for a Mumbai University student

I have a query regarding the applications to the MIM schools.
I havent heard an answer from anyone so i hope someone can help me out here.

I have completed my Engineering from Mumbai University in India with an aggregate of 66%
It might seem low however getting anything above 60 in Mumbai or Pune university is considered very good(our toppers are around 75-78 percent mark)

Ok,so my question is,how will this impact my application to schools for MIM?
Do the admins know about the strict universities like Mumbai and Pune?
A lot of other universities have students with percentages more than 85.But Mumbai and Pune University are reputed.

My list includes mainy HEC paris,LBS,ESCP europe and ESSEC.
Are the universities in France aware of the strict marking scheme in some universities in India?

I havent had a chance to interact with any student who is from Mumbai University has completed engineering and is pursuing MIM.
I'd really appreciate if someone could help me put here.

Thanks and regards,
Aditya.
