Thanks mayamkhob...lol...I just had another good laugh.  Yes, they can both be used as adjectives...the funny thing is that some people use them interchangably when they actually have opposite meanings...that is why it is so funny when they say "reputed company" because they are actually saying that it is not a real company and that there is not substantive proof to indicate that it is a real company....whereas a reputable company is a company with a good reputation...hence the humor all of us who know English enjoy by the use of "reputed". Thanks again.
