If someone appreciates a help and in a polite way says thank you it is a custom to response to the person by saying "you welcome" or "You are most welcome". But sometimes people just say "no problem". Does "no problem" have same application as "you welcome"?
Thank you in advance.
I would use "you're welcome" if I was responding to a simple "thank you" for a normal polite action, for example - if someone asked me to pass the pepper at the dinner table.
I would use a "you are most welcome" when I received a very polite "thank you". Say I was a clerk at a store and someone wanted a particular service. I performed this service, perhaps a little better than normally expected. The customer says, "Thank you very much, I really appreciate your help!" Then I might blush and respond "You are most welcome."
