Calculate voltage regulation and efficiency of the transformer.

Please be as detailed as possible. I solved this problem but the examiner didn't give me marks for it. No matter how much I try I can't figure out my mistake. Now I am thinking if I have understood this topic in the wrong way. So please help me to solve the problem and final results of V.R. and efficiency will be very much appreciated since I can compare my answers with the correct one. Thank you.
