You do NOT need to write any addresses.
Begin your letter as follows:

Dear…………,

Write at least 150 words.

Model Answer:

Dear Mr Peter,

I am a final semester Economics student of your college and I am writing this letter to enquire whether there is an alternative for the seminar which I failed to attend on ‘Modern marketing techniques’ at the department seminar hall last Wednesday.

I came to know from my friends that there were very useful classes on the fast-changing demands of the modern man and the strategies which have to be taken accordingly. Unfortunately, I could hardly attend it as I was hospitalized at that time. As an eight semester student, seminars on these types of topics are very much important for me and taking part in it can help me in a great way in completing my project work successfully. It would be appreciated if you could inform me whether you have such seminars charted in the current academic year.

I look forward to your reply.

Yours sincerely
