1. What is a Business Letter?
A business letter is a formal written communication between two companies, between a company and a client, or between an individual and an organization. Unlike a personal letter, it uses a polite, professional tone, follows a strict structure, and avoids slang, contractions, and emotional language. In the CBSE board exam, you are often asked to write a business letter of about 100–120 words, typically placed inside a box. The letter may be an order, an inquiry, a complaint, or an application related to a commercial or official context.
2. The 8 Essential Components
- Sender's Address: Your address at the top left. No name here; it appears after the signature.
- Date: Written below the sender's address. Format: 25 April 2026.
- Receiver's Address: The designation and address of the person or company you are writing to.
- Subject: A clear, concise line stating the purpose of the letter. E.g., "Subject: Order for school furniture."
- Salutation: "Dear Sir," or "Dear Madam,". If the name is known, "Dear Mr. Sharma,".
- Body: Usually three paragraphs — introduction, main details, conclusion. Keep it brief and focused.
- Complimentary Close: "Yours faithfully," (when salutation is "Dear Sir/Madam") or "Yours sincerely," (when name is used).
- Signature: Your full name and, if relevant, designation, written below the close.
3. Full Block vs Modified Block Format
- Full Block Format: All elements are aligned to the left margin. No indentation. This is the most common and recommended format for board exams. It is clean, modern, and easy to read.
- Modified Block Format: The sender's address, date, and complimentary close are aligned to the centre or right. The body is left‑aligned. This format is a bit more traditional. For your exam, the full block format is usually the safest choice unless specified otherwise.
In this post, all solved examples are presented in the full block format, as preferred by the CBSE board.

Through the columns of your esteemed newspaper, I wish to highlight the deteriorating condition of public parks in the Andheri West area. Broken benches, overgrown grass, and heaps of uncollected garbage have made these parks unusable for residents.
Parks are vital for the community, especially for children and the elderly. I urge the municipal authorities to repair the facilities, restore greenery, and ensure daily cleaning. Regular inspection by a dedicated team can prevent further neglect.
I hope my letter finds space in your newspaper and leads to swift action.
