Que / Quien

Que / Quien
 

Hi all,

I have encontered these two phrases:

• las personas quien tienen dificultades económicas
• la persona que iba sentada delante

Is there a reason why the first one uses "quien" and the second one uses "que", or both may be used?

Thanks for your answers,
Yendred

The author, or the translator, of the sentence made a mistake when they wrote 'quien'. It has to agree in number with subject - "las personas quienes tienen ...".
But it sounds much more natural to use 'que' - "las personas que tienen ...".

I fully agree with Rusty.
