Answer:
Dear Preet Vihar,
I am writing to you because I have lost my original certificates of classes 10 and 12, and I would like to get a duplicate, but I would need information on how to proceed.
Firstly, I would like to know the cost, and if there are different modes of paying? Is it possible to use credit cards?. Also, could you inform me how many days does it take the board to issue the duplicates?. Lastly, could you tell me if there are any other formalities to get the certificates?
I want to thank you in advance for your time. I am looking forward to your reply.
Yours sincerely,
Tarun Karuna.
Step-by-step explanation:
When we write a formal letter in the first paragraph, we have to state why we are writing. Then, in the second paragraph, we have to develop our inquires. To ask questions formally, we use phrases such as, could you inform, could you tell me, I would like to know, amongst others. In the last paragraph, we thank the person and use a closing sentence. Lastly, as we have the person's name, we use yours sincerely at the end. If we do not have the name, we write at the beginning, dear sir or madam, and at the end, yours faithfully followed by our signature in both cases.
