"They have less food than you."

Translation: उनके पास आपसे कम खाना है।

Why is it aapse instead of tujhese?

[BorayinMai]

I agree that tujhse should also be accepted. One can't know from the English which "you" is implied.

[Mohan.g0]

I selected तुझ से. It was accepted.

[juggledean]

I guess that formality is somehow implied. Nice username!

What is the diff btw 'unsae' and 'unke'

[avaraana]

से is used for comparison - उनसे would roughly be "than them", उनके would be 'to them'.

[avaraana]

Why is it है and not हैं ?

[GabrielBou109736]

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)

[PriyaSinghJatti]

उनके पास आपसे कम खाना हैं should be correct because it is multiple people, i.e. they

[Ellen147987]

No, 'food' is the subject here.
