Why not "find out"?

Hi Irina,

To work out the answers implies that you are trying to solve the answers yourself.

However, if a person was to find out the answer, this would mean that they would probably have to ask someone else to provide them with the answer or obtain the answer from a different source of information.

Regards,
Mark
