"What is her age?"

Translation: Hvad er hendes alder?

[YDaskaloff]

It also accepts "Hvor gammel er hun?" As an answer which is nice :)

[MMR_LM]

Is this the common way of asking someone's age in Danish?

[Rito729011]

why is it hendes, it should be hende

[BernhardMa1]

It is a possessive pronoun. "Her age" (the age of her)

[Sandra261542]

could i say "havd gamle er hendes?"

[Chris308133]

I put hende alder and got it wrong. is it hendes rather than hende because of it being a possessive adjective? Because we don't say hers age in English, just her age.
