Why is it aapse instead of tujhese?
I agree that tujhse should also be accepted. One can't know from the English which "you" is implied.
I selected तुझ से. It was accepted.
I guess that formality is somehow implied. Nice username!
What is the diff btw 'unsae' and 'unke'
से is used for comparison - उनसे would roughly be "than them", उनके would be 'to them'.
Why is it है and not हैं ?
Because food खाना is singular or non-countable, and with "-के पास ... हैं/है" construction, हैं/है depends on the number of the object possessed. If it was बिल्लियाँ, it would be हैं.
That's how I get it, please someone correct me if I'm wrong.
@shri212262 Unsae is them
Unke is theirs
Unsae jaake pucho (Ask them)
Yeh unka hai (it's theirs)
उनके पास आपसे कम खाना हैं should be correct because it is multiple people, i.e. they
No, 'food' is the subject here.
